TL;DR: 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/CZIF-8 sample, and this work will contribute to the improvement of the cathode materials of commercial LIB.
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 (CZIF-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/CZIF-8 sample The N2 adsorption and desorption isotherm suggests that the coating layer has uniform and simple connecting mesopores As cathode material, LFP/CZIF-8 cathode-active material delivers a discharge specific capacity of 1593 mAh g−1 at 01C and a discharge specific energy of 1417 mWh g−1 after 200 cycles at 50C (the retention rate is approximate 99%) These results are attributed to the synergy improvement of the conductivity, the lithium ion diffusion coefficient, and the degree of freedom for volume change of LFP/CZIF-8 cathode This work will contribute to the improvement of the cathode materials of commercial LIB Highlights: 1 A surface modification layer, which has 10 nm with metal zinc and graphite-like carbon, was synthesized on commercial LiFePO4 (LFP) using ZIF-82 As-prepared LFP/CZIF-8 possesses prominent electrochemical performances with a discharge specific capacity of 1593 mAh g−1 at 01C and a discharge specific energy of 1417 mWh g−1 after 200 cycles at 50C
