A silicon anode battery is a type of lithium ion (Li-Ion) battery where the anode is replaced by silicon nanotubes or silicon coating. The idea of using a silicon anode in a battery is still under a lot of testing. This has multiple advantages over ordinary lithium or graphite anodes. The silicon enables long life and high energy storage, resulting in a significantly longer lasting battery.
Techopedia Explains Silicon Anode Battery
Silicon anode batteries promise a long battery life as well as long-lasting storage due to the high capability of silicon to store potential. The introduction of silicon as a part of anode has the potential to change Li-ion batteries significantly. The anode can increase up to four times its original volume during charging due to lithium accumulation on its surface and upon discharging, the anode returns to its original size. This repeated expansion and contraction places great strain on the silicon, hence the charge/discharge cycle for conventional silicon-based anodes is typically kept short.
