So, when several of you left comments pointing me in the direction of a new company that’s replacing a key part of the battery with silicon and some nanowires, my curiosity was piqued. To add to that, one of my science advisory team members brought them up, too, which only added fuel to the curiosity fire. Now, we’ve covered a lot of batteries on this channel, so what makes the company Amprius, and other similar companies going after silicon, stand out for the future of battery tech?

Silicon batteries might be where the industry is headed but that doesn't solve the lithium ion battery issues with EV. Look up what the legacy automakers are saying, many like Toyota, Honda, Ford and GM are pulling away. The CEO of Honda Toshihiro Mibe said they are ending development of an affordable EV. What it comes down to is the business model. They'd need to profit from the entire vehicle manufacturing process and that wont happen with the EV business model.

You can make silicon nanowire cheaper: atomic layer deposition instead of "growing it directionally". You deposit lattices which are folded In a scrungy knotstructure. This would also allow swelling to occur without damage since the structures simply seek to "un-knot their not-knot" such that no stretching occurs. Bends would naturally reform through discharge cycles because of electron movement so the dendrite forms useful reformation of any weakness in bends

PWCs, patient lifts, tracked ceiling lifts, CPAP machines, the list goes on. Having a battery thats super energy dense and charges fast (but also just as important, doesnt degrade abnormally fast) would be a godsend to people with disabilities in PWCs and MWCs w/ power assist! Depending terrain and other conditions, a Permobil and Quantum can avg 4-9miles on a single charge before it has to be down for 3-4hrs to get back to 100% If batteries like this allow a person to achieve double, if not triple, the range and only take about 2hrs to fully charge (or faster) that would be life changing for people with PWCs!

Price is an issue though with attrition wars like the one in Ukraine. So even a military likely would favor cheaper shorter range drones for the bulk of the fleet and only use the increased range or lighter smaller drones with this battery tech for the use cases that truly makes them cost effective. I think one thing I have realized with the Ukraine war is that our military might be very capable but its way too expensive to keep fighting a real war for the years needed to defeat a peer adversary. If we don't mass produce cheaper munitions that are effective enough for their roles and reserve our fancy high tech stuff for the edge cases when you get super good bang for buck we will lose the next war.

Also, they are not in production and it's not clear when they will be in mass production. Enovix is currently ramping their new factory for their silicon anode batteries which will be in production in 2024, and they have hinted that they have deals in place with major phone OEMs (rumored to be Apple and Samsung). So Enovix will probably beat Amprius to market by at least 1 or 2 years and at a lower cost. Enovix also has a unique battery structure that prevents fires, which means that they might be used in cars once the production volume gets high enough, probably around 2026.

Your range anxiety is self-imposed. Maybe driving an EV in ND four years ago, without charging infrastructure, in the winter was not a good idea. Would it be the same today?

I plan ahead so as to not experience range anxiety.
@hammerfist8763 5 місяців тому
Anxiety has nothing to do with it. These are cold hard facts. We had enough charging infrastructure 4 years ago to support 120 mile range. At -25' Farenheit, 335 mile range becomes about 140, especially if driving into a headwind, so that's cutting it pretty close. I drove a 2020 Model X with 295 mile range from MN to Fargo at -20 F into a 20mph wind in 2020. Range reduced by about 60%. Stopped and charged to 100% in Alexandria. That's 108 miles along 94 to Fargo. Even with heat cut and at 60 mph, rolled into the Fargo supercharger with 3% charge left (about 4 miles at that temp). EV's need more range and faster charging to have the same utility as ice vehicles. They're not a good choice if you have to keep an ICE as backup. LI-OH batteries suck in the cold, charge slow, and don't last if supercharged often. Just ask anyone who used a Model 3 for Uber.

The factory had to install it's own massive generator, that generator used fossil fuels. I think a hybrid system is better. There is a trucking company from Canada that has built it's own hybrid truck. Edison is the name. I think batteries have their place. But being able to charge them without stopping is a major plus.

The major problem in the past was the longevity of Amprius batteries. Amprius now claims 90% capacity retention after 1200 cycles in its eVTOL flight protocol testing for its 370 Wh/kg packs, but we don't know what was the depth of discharge in those tests. Previously Amprius said between 200 and 1200 discharge cycles, so maybe Amprius has dramatically improved the degradation of the battery since then or maybe it was testing in an optimal range between 30% and 70% depth of discharge to get the least battery degradation. Without more public data, we really don't know. The silicon nanowires are grown in three stages with CVD, and Centrotherm's plasma-enhanced chemical vapor deposition (PECVD) equipment is used, which has to be expensive compared to graphite anodes. I doubt that this tech will ever get cheap enough to compete with standard batteries used in EVs, so it is probably just for high-end supercars.

Dear m barefoot, You raise a very good question. I will speak as a retired EE and an amateur chemist, mainly for July 4th. Both carbon as charcoal or Carbon powder as in gun powder are quite combustible given Oxygen in sufficient concentration. As you know, completely burning Carbon gives co2. Burning Si gives SiO2, the main ingredient in sand. So point is both are flammable. In any Redox based li ion cell, the amount of Li stored in the anode with cell charged determines the chemical reactivity. Conventional graphite,a form of Carbon, stores only 1 Li atom for 6 Carbon atoms. Si holds far more, therefore more energy in a smaller space. To make use of more Li, the cathode must become a larger store of Oxygen, for when the Li moves to the cathode where it "steals" Oxygen from the metal oxides mix there. Li is a Lot Hungrier for Oxygen than nickel or manganese or Cobalt is. When a + lithium ion arrives at the cathode, it gets oxidized and leaves a positive charge there. Having just left the anode, a negative charge gets make there and current can flow,.and motors will spin. Back to safety. More stored Li needs more stored Oxides or other oxidizing stuff to Balance the Reaction. So simply put in 4th of July terms, the more Gunpowder the bigger the BOOM. NEWER LI BATTERIES SEEK TO PACK MORE FUEL (LITHIUM, SILICON, possibly plastic separator, possibly organic carbonate electrolyte INTO THE SAME PACKAGE AND ADD MORE OXYGEN TO BALANCE THE REACTION. So again HIGHER ENERGY BATTERIES ARE A BIGGER FIRECRACKER/FIREBOMB. sorry if this hurts your EV visions.

I mention this every time someone claims we will see really fast ev charging. Let's assume a 20% to 80% day charge on a 100kwh battery. So that's 60kwh of energy that needs to be added to the battery. To do that in 6 minutes, 60kwh / (6/60) = 600kw charge rate on average assuming no losses. The NACS connector is rated for 250kW, so you'd need 3 of them per car, so there is an issue with simply delivering the power from the station to the car. Not too mention that if you want to charge 4, 6, 8, 10 cars at the same time you could find that the station needs a small power plant (6MW) onsite just to handle the peak loads. Basically the infrastructure required around the charging station is going to limit our ability to charge multiple vehicles at a time at these high rates even if we solve the battery side.

I wonder how dirty silicon refining will be "than we previously thought" ? A quick search reveals: "...Raw quartzite is mostly silicon dioxide (SiO2), and the refining process begins with a reduction reaction to get rid of the oxygen. Crushed quartzite is mixed with carbon in the form of coke (coal that has been heated in the absence of oxygen). Woodchips are added to the charge as well; they serve both as a carbon source and a physical bulking agent that allows gasses and heat to circulate better in the furnace. The arc furnaces for silicon smelting are massive installations with huge carbon electrodes. The electrodes are consumed during smelting, so new electrodes are screwed onto the tops of the current electrodes to make sure the process isn’t interrupted. The arc furnace requires massive amounts of electricity to maintain the 2,000°C temperature needed, so silicon refineries are often located where electricity is cheap and plentiful. The reduction reactions inside the melt zone are actually pretty complicated, but can be summed up with two main reactions: SiO2 + 2 C > Si + 2 CO2 SiC + SiO2 > 3 Si + 2 CO In both reactions, the oxygen in the silicon dioxide combines with carbon to form the main waste product, carbon monoxide. A side reaction that occurs in a part of the melt zone inside the furnace produces silicon carbide (SiC), which is an unwanted byproduct (at least when the goal is to purify silicon; silicon carbide itself is a useful industrial abrasive). By making sure that silicon dioxide is far in excess in the furnace, the second reaction where the SiC acts as a carbon source for the reduction of silicon dioxide is favored, and silicon with up to 99% purity can be tapped off the bottom of the furnace." as clean as a whistle (a burning carbon whistle blown with a CO2 supply)

Obviously graphene will .. leap ahead of several sub-tech product cycles being designed into markets. Getting a solid short state of the times update clip out there could help ensure some of these product cyclings are more quickly turned into products *to* cycle through .. helping to add a bit o' 'fat' to the tech types available vs them sorta just being plowed over by a next-gen tech that essentially makes them.. ..unnecessary.

To charge that energy in 6 minutes would require 240 Kw (Kw is the rate, not the total energy). 240 Kw, assuming 220 VDC to the vehicle would be about 1000 amps. That is a HUGE amount of current, especially when exposed to weather and casual use by non expert motorists (potentially extremely dangerous). And that is each and every station while the chargers are in use. It's NOT like charging a cell phone.

Definitely longevity is something to be concerned about, but if the benefits of their battery are high enough and very importantly, also don’t increase the costs too much, even 2000 charge cycles might be sufficient for a lifespan. It could potentially push manufacturers to engineer vehicles, aircraft etc. in a way that permits faster and lower (labour) cost battery replacement. And while as low as 2000 cycles would be not great, at 50% additional energy density it would mean an average commuter would quite likely get 2 days of use out of it, so 4000 days which is roughly 11 years. For typical use of my family’s EV, that would actually easily be 3 days worth of travel. The economics of such a system could conceivably work but the devil is in the details for sure.

I am a robotics engineer and have worked at an autonomous drone factory and this battery looks good for that industry. They would be happy to pay double the price to get 30% more flight time just from upgrading the battery. As for cars, they need sooo many battery cells just to make a car and the price is already high for an electric car. Perhaps for PHEV vehicles as their battery is smaller than pure EV, otherwise the cost goes up too much except for Rivian or other exotic super EV cars, perhaps those hypercars could use it.

It is these types of incremental developments that I see having the most promise. This alongside high nickel monocrystalline chemistries on the cathode side will push NMC type batteries further. I am sure LFP is progressing but I don't follow that as closely (it should benefit from a silicon anode too though, no?). For EVs I am happy with the current range available at 64KWh (at least it works for where I live). However the batteries need to get more energy dense in order to half the weight of the battery. On good roads an EV is great but you can really feel the weight on rougher roads. Lower weight battery equals softer suspension and ultimately longer range in practice as all the other components of the car such as brakes can be lighter. A virtuous circle if ever there was one.

Ground transport will be reserved for recreational driving and mass cargo transport, and mass transportation (bus, school, Trams, rail,) make it illegal to use road vehicles to go to work.

For EVs, I think we've already reached the point where, for most applications, making batteries cheaper is more important than making them denser. Even EV semi trucks have already been built using today's battery technology, and the primary limitation on their usage arises from the cost of the batteries, not their weight. Where improved energy density will really matter is aviation, as airplanes are much more weight-sensitive and much less cost-sensitive than cars and trucks. If we ever want even the shorter commercial airplane flights to be electrified, we need big improvements in battery energy density, with the research shown in this video a good start in that direction.

Well, one element is missing in this very interesting video. The high reactivity of silicon in its metallic state. Nanoparticles and nanowires are extremely sensitive to oxidation, and the resulting silica is not a good binder to Lithium. That's also one of the strength of the graphite/graphene mixture with Li nanoparticles, the carbon lattices serving as protection (partial) to the nanoparticles. The only problem lies in obtaining them as crystalline pristine metallic Si, but that may have been solved in an economically viable way, with a recent patent.

By the way, the Amprius 450Wh/kg battery is alreafy commercially available and Amprius has announced a higher density 500Wh/kg model. NASA has published papers showing 500Wh/kg is the density that makes regional electric airline routes viable.

Good video, Matt. I'm a proponent of battery powered everything. I use them in my model airplanes almost exclusively. There are issues with the reality of societal battery conversion that nobody seems to address. It's not range anxiety, battery density, cost, or charge time. I'm hoping you'll read this and use your level-headed approach to explain the math to me and your viewers about the following: One issue is the amount of current (amps) required to charge a 100kwh battery to 80% in 6 minutes. This issue has multiple levels of difficulty, including the basics like charger capacity, charger cable/connector, and the heat created at the charge rate required. Then there is the infrastructure and power generation problem. It's not all that big of a deal until you start talkin about 10s of millions of cars, busses, semis or airplanes all needing high amperage at the same time. I'm not trying to be a downer but it would be nice for someone like yourself to take a real look at the numbers and report honestly on the feasibility. I think society is not well served by saying, "We'll have 1500km range batteries with 6 or 10 minute charge times," without stating that it is not currently (pun intended) possible and won't be possible for decades. It would be great to see the actual math on how much current is needed to charge 1 million, 10 million and 100 million 100kwh battery all at the same time, at night or when people aren't driving. The number of power plants required, the time it takes to build the facilities with current regulations, and the cost to do so, would also be good information to share. We should always look to the future but the reality of today can't be ignored. And let's not even start to talk about the power usage of future crypto mining. Thanks in advance.

Battery technology - especially mobile battery technology - hasn't really changed in decades. Moving from NiCad and Ni-MH to Lithium-ion and LiPo was a major thing. But since then we've only seen slow-and-steady gradual refinements and iterations, basically about 5%-10% more energy capacity, density, performance, efficiency every few years. This all adds up over the years. Batteries today are much better than batteries last decade. But all that being said ... Samsung and Apple and Tesla will overhype and oversell even the tiniest little improvement. So consumers are (mis)led to believe that somehow their latest-and-greatest expensive new smartphone has a killer battery which just blows everything else away. We need more videos like this. Facts vs expectations vs promises.
@BryanTorok 5 місяців тому
While how fast a battery can accept a charge is an important factor, one als o needs to consider how fast you can deliver the power, i.e. how much current time voltage the charger can deliver. That is the limiting factor for most home chargers and even for commercial chargers. As for battery chemistries, China is currently building plants to produce sodium ion batteries. They are currently about 10% less energy dense, but that is expected to improve. There big advantage is that sodium (salt) is cheap and plentiful and that sodium ion batteries are much safer and less likely to catch on fire.

Swapping carbon for silicon would form an intermetallic compound with a FCC crystal structure. The solution would be to make the intermetallic compound Li4Si. Powder it to extreme fine dust, then mix with aluminum and bind to the aluminum collector plate with sintering. Would be a little less density than silicon nano rods, but would be much higher prompt current capacity. Now let's work on the cathode material, replace the cobalt...❤

gosh , just make silicon Nano wire itself , then think how to stack it (you know , the same way we do for normal copper wire , just a little bit hotter for elasticity (just stretch it)) we could as well just place some layers (like honeycomb) and smelt them a bit after. Or just lodge into some material vertically (like hairs into toothbrush )) Anyhow nano wire would be a good start as I see it. (just stretching/pulling material is much easier then grow it , by the way I have a few more nice ideas for example for long term storage via mesh of resistors [x , y] (without diodes) - it turns out that connecting wires in certain way you could calculate value/ nominal of resistors in such a mesh(massive of resistors), Just metallic structure without semiconductors (those would be only in peripherals to connect wires to conduct measurement , this thing therefore could be very durable, and potentially very easy to produce.
