The Surface Coating of Commercial LiFePO₄ by Utilizing ZIF-8 for High Electrochemical Performance Lithium Ion Battery.

ABSTRACT: The requirement of energy-storage equipment needs to develop the lithium ion battery (LIB) with high electrochemical performance. The surface modification of commercial LiFePO₄ (LFP) by utilizing zeolitic imidazolate frameworks-8 (ZIF-8) offers new possibilities for commercial LFP with high electrochemical performances. In this work, the carbonized ZIF-8 (C_ZIF-8) was coated on the surface of LFP particles by the in situ growth and carbonization of ZIF-8. Transmission electron microscopy indicates that there is an approximate 10 nm coating layer with metal zinc and graphite-like carbon on the surface of LFP/C_ZIF-8 sample. The N₂ adsorption and desorption isotherm suggests that the coating layer has uniform and simple connecting mesopores. As catho
