Fabrication and electrochemical characteristics of crack-resistant si-based anode materials for all-solid-state thin-film batteries

A series of Si-Zr and Si-Zr-Ag films were prepared by the co-sputtering method to examine their microstructural stability and electrochemical performances. Si-Zr thin films like Si 58 Zr 42 and Si 48 Zr 52 , alloyed with significant proportions of Zr, show excellent cycle performance with no microst...

Description
Summary:A series of Si-Zr and Si-Zr-Ag films were prepared by the co-sputtering method to examine their microstructural stability and electrochemical performances. Si-Zr thin films like Si 58 Zr 42 and Si 48 Zr 52 , alloyed with significant proportions of Zr, show excellent cycle performance with no microstructural change to the film surfaces, although they exhibit a reduced reversible capacity. Si-Zr-Ag film shows a charge-discharge profile with a plateau-like region, in which the cycle performance and the morphological stability depend on film fabrication conditions such as the substrate and the applied bias voltage.
