Lithium intercalation into amorphous silicon thin films

Electrochemical lithium intercalation into a-Si:H thin films grown on stainless steel substrates at temperatures of 100 and 250 degrees C was studied. The intercalation capacity of films grown at 250 degrees C is similar to 1750 and similar to 500 mA h/g in the first and hundredth cycles. The lithium diffusivity in films is similar to 10(-12) cm(2)/s.
