Silicon promises longer-range, faster-charging and more-affordable EVs than those whose batteries feature today’s graphite anodes. It not only soaks up more lithium ions, it also shuttles them across the battery’s membrane faster. And as the most abundant metal in Earth’s crust, it should be cheaper and less susceptible to supply-chain issues.
Instead, Group14 is pioneering the use of high-silicon anodes in conventional lithium-ion batteries, which enables impressive energy densities and vast improvements in power density. He believes solid-state cells have a lot of potential, but his company’s technology is ready now.
The electrification of everything “it” chemistry lies with silicon-based anodes, immediately turning today’s li-ion batteries into lithium-silicon batteries.
Sodium, common in ocean water and soda ash mining, is an inherently more environmentally friendly battery material. The LESC research has made it a powerful one as well. Innovative architecture To create a sodium battery with the energy density of a lithium battery, the team needed to invent a new sodium battery architecture.
When adopted, the lithium-silicon battery will replace the current lithium-ion battery, thus enabling the true electrification of everything today—not tomorrow. Replacing our energy dependence on the finite supply of fossil fuels as well as tackling climate change (emissions) are complicated undertakings.
A long-standing goal for anode innovation with lithium batteries has been to leverage silicon as an active material inside of the anode, creating a lithium-silicon battery. Lithium-silicon batteries have the potential to hold huge amounts of lithium ions due to silicon’s 10x higher capacity than graphite.
