Lithium intercalation into amorphous silicon thin films

Abstract

Electrochemical lithium intercalation into a-Si:H thin films grown on stainless steel substrates at temperatures of 100 and 250°C was studied. The intercalation capacity of films grown at 250°C is ∼1750 and ∼500 mA h/g in the first and hundredth cycles. The lithium diffusivity in films is ∼ 10−12 cm2/s.
