6 FAQs about [Silicon powder for battery production]
Can silicon anode materials be used as drop-in additives for lithium-ion batteries?
Silicon anode materials have shown great potential as drop-in additives to increase the efficiency and energy storage capacity of lithium-ion batteries. Until recently, their principal drawback has been surface oxide passivation, a process which increases impedance and reduces cyclability in the anode.

Why is silicon important for lithium-ion batteries?
The silicon we produce is key to achieving reliable and sustainable industrial-scale production of advanced materials for lithium-ion batteries – and is therefore destined to make an important contribution to the future of our planet.
Can silicon be used as a lithium battery anode?
In fact, silicon’s first documented use as a lithium battery anode even predates that of graphite— by seven years. But experiments with that element have been plagued by technical challenges—including volume expansion of the anode when loaded with lithium ions and the resulting material fracture that can happen when an anode expands and contracts.
Should EV batteries be made out of silicon?
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.
