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.

New high energy, highly stable cathode for sodium-ion batteries

Green Car Congress

F 0.7 , for sodium-ion (Na-ion) batteries (NIBs). This new material provides an energy density of 600 Wh kg –1 , the highest value among Na-ion cathodes. Recently, attention has been refocused on room-temperature Na-ion batteries (NIBs) as a low-cost alternative technology as compared to LIBs. Click to enlarge.
