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.
Silicon is the best material for energy density. Using more silicon means that we can provide lithium-ion batteries with higher energy density, while at the same time enabling the highest ratio of energy to power. Amprius Technologies’ Silicon Batteries have excellent cycle life that is continuously improving.

A new anode material is required to improve battery performance, and that material is silicon. Silicon can store up to 10 times more lithium compared to graphite which enables batteries to have much greater energy. But silicon swells dramatically when it is charged with lithium and that can cause it to crack and stop working.
Li-Si materials have great potential in battery applications due to their high-capacity properties, utilizing both lithium and silicon. This review provides an overview of the progress made in the synthesis and utilization of Li-Si as anodes, as well as artificial SEI and additives in LIBs, Li-air, Li-S, and solid-state batteries.
Batteries with a small amount of Si have already been commercialized; interestingly, Tesla Motors incorporated Panasonic lithium-ion cells with a SiO x and carbon-based anodes in their Model X and Model 3 vehicles, demonstrating the practical implementation of these advancements (5% of Si in the anode of the Panasonic cells of the Tesla X) .

Silicon (Si) has emerged as an alternative anode material for next-generation batteries due to its high theoretical capacity (3579 mAh g –1 for Li 15 Si 4) and low operating voltage (<0.4 V versus Li/Li +), offering much higher energy density than that of conventional graphite anodes.
Silicon (Si) stands as a promising candidate for high-capacity anode materials in the next-generation lithium-ion batteries (LIBs) due to extremely high specific capacity. However, silicon application is hindered by its inherently poor electron and ion conductivities, as well as structural instability during the repeated charging/discharging.
