Abstract
In this study, we report on the preparation of n-type doped ~ 400 nm thick amorphous Si thin film on a surface of 9 µm rough
current collector. The electrochemical cycling test of designed anodes revealed that Si thin film on the surface of rougn exhibited
stable capacity retention ( ~ 67 µAh cm
-2
) for 120 cycles. Rate capability test showed the unaltered performance of prepared
electrode after applying a current rates up to 300 µA cm
-2

1. Introduction
Lithium ion batteries (LIBs) are the best technology among secondary battery technologies due to high
volumetric and specific energy density. Meanwhile miniaturization of portable electronics, small and microscale
devices requires a design of high capacity, lightweight and small size energy sources.
