Siloxene as promising silicon intercalation anode for Li-, Na- and K-ion batteries

Green Car Congress

Researchers in France have shown the versatility of siloxene, a 2D silicon structure (Si 6 O 3 H 6 ), as an anode material for Li-, Na- and K-ion batteries. It is one of the most promising anodes for lithium-ion (LIB) and sodium-ion (NIB) batteries due to its high theoretical capacity 3590 mAh/g for Li 15 Si 4 and 954 mAh/g for NaSi.
