High performance of thick amorphous columnar monolithic film silicon anodes in ionic liquid electrolytes at elevated temperature

The cycling performance of thick (about 7 μm) amorphous columnar monolithic film silicon anodes was studied in ionic liquid based electrolyte solutions. Cycling results obtained for these Si anodes in 1-methyl-1-propylpyrrolidinium bis(fluorosulfonyl)imide-based electrolyte solutions are superior to...

Description
Summary:The cycling performance of thick (about 7 μm) amorphous columnar monolithic film silicon anodes was studied in ionic liquid based electrolyte solutions. Cycling results obtained for these Si anodes in 1-methyl-1-propylpyrrolidinium bis(fluorosulfonyl)imide-based electrolyte solutions are superior to those demonstrated in LiPF 6 /fluoroethylene carbonate/dimethyl carbonate electrolyte solution under identical conditions.
