Battery Technology: A New Era Emerging
The continuum of battery technology development has been varying from stagnant periods to significant breakthroughs, in an almost unpredictable fashion. The inception of the idea about a battery charged-electric vehicle is indeed as old as the motor car itself. The trend has been consistently directing away from heavy and acid batteries to compact, light and far more efficient nickel/metal (NiMH) accumulators. One of those significant breakthroughs mentioned above came with the introduction of lithium-ion technology. Of course, many additional technological advances seem to be imminent, within the next years, through the introduction of post-lithium-ion technology.
Lithium-ion batteries are named after the movement of lithium ions within them, and they power most rechargeable devices today. The element lithium (Li) has some interesting properties that allow batteries to be both portable and powerful; the 2019 Nobel Prize in Chemistry was awarded to scientists who worked on the idea during the 1970s. But despite their widespread use, lithium-ion batteries remain extremely complicated and still intrigue scientists to unlock their secrets and open up the road for optimal efficiency.

▶1. Nickel Powering Battery
Nickel (Ni) has long been widely used in batteries, most commonly in nickel cadmium (NiCd) and in the longer-lasting nickel metal hydride (NiMH) rechargeable batteries, which came to the fore in the 1980s. Their adoption in power tools and early digital cameras revealed the potential for portable devices, changing expectations of how we work and live. The mid-1990s saw the first significant use of NiMH batteries in vehicles in the Toyota Prius. Around the same time, the first commercial applications for Li-ion batteries emerged, initially in camcorders and eventually finding their way into smartphones, laptops and the numerous other portable devices we now take for granted.
The major advantage of using nickel in batteries is that it helps deliver higher energy density and greater storage capacity at a lower cost.

▶ 2. What is a solid-state lithium-metal battery?
A solid-state lithium-metal battery is a battery that replaces the polymer separator used in conventional lithium-ion batteries with a solid-state separator. The replacement of the separator enables the carbon or silicon anode used in conventional lithium-ion batteries to be replaced with a lithium-metal anode. The lithium metal anode is more energy dense than conventional anodes, allowing the battery to store a greater amount of energy in the same volume. Some solid-state designs use excess lithium to form the anode, but the QuantumScape design is ‘anode-free’ in that the battery is manufactured anode free in a discharged state, and the anode forms in situ on the first charge.

▶ 3-1. Vanadium Redox-Flow Battery | Schmid
Construction looks set to begin on a factory building flow batteries, as a joint venture (JV) formed by German tech company Schmid Group and Saudi Arabian investment company Nusaned closed the transaction to seal its partnership.
The JV's formation was announced this time last year and Schmid emailed Energy-Storage.news yesterday with news that the transaction has received regulatory approvals and satisfied its closing conditions. Schmid and its partner Nusaned - which is owned by SABIC, a chemical manufacturing subsidiary of Saudi Aramco - will focus on developing vanadium redox flow battery technology as well as manufacturing.

▶3-2. Vanadium Ion Battery | Standard Energy
Standard Energy, a vanadium ion battery developer, announced today it has raised a $8.9 million Series C from SoftBank Ventures Asia. The South Korea-based company says its batteries’ advantages over lithium ion include less risk of ignition and the ease of sourcing vanadium. The latter is an important selling point, as electric vehicle makers face a potential shortage of lithium ion batteries.
Instead of serving as a replacement for lithium ion batteries, however, Standard Energy chief executive officer Bu Gi Kim said they complement each other. Vanadium ion batteries have high energy, performance and safety, but they are not as compact as lithium ion batteries.
