Si nanoflake-assembled blocks towards high initial coulombic efficiency anodes for lithium-ion batteries.

Si nanoflake-assembled blocks towards high initial coulombic efficiency anodes for lithium-ion batteries. Chem Commun (Camb). 2018 Oct 12;: Authors: Zhou X, Ren Y, Yang J, Ding J, Zhang J, Hu T, Tang J Abstract Assisted by artificial amorphous copper silicate, Si with a flake-like structure was obtained through a facile magnesiothermic reduction. The Si anodes exhibit excellent cyclic performance and rate performance. Particularly, a high initial coulombic efficiency of 85%-89% was obtained due to their greatly reduced surface and internal defects. PMID: 30310889 [PubMed - as supplied by publisher]
