The electrochemical cycling test of designed anodes revealed that Si thin film on the surface of rougn exhibited stable capacity retention (∼67µAhcm-2) for 120 cycles. Rate capability test showed the unaltered performance of prepared electrode after applying a current rates up to 300µAcm-2enAttribution-NonCommercial-ShareAlike 3.0 United Statesrough current collectorsiliconthin filmn-type dopedamorphousmagnetron sputteringlithium ion batteryN-type doped amorphous Si thin film on a surface of rough current collector as anode for Li-ion batteries [Article]Article© 2018 Elsevier Ltd.
