Abstract:
In order to improve high rate and cycle performances of commercial LiFePO4 (LFP), mesoporous carbon (MC) is synthesized by carbonization of zeolitic imidazolate frameworks-8 (ZIF-8). As an additive, MC can improve both electronic conductivity and lithium ion diffusion coefficient of LFP due to its high conductivity and mesoporous structure. LFP mixing with MC delivers a high rate performance of 154.6 mAh g(-1) at a current rate of 0.5 C and a capacity retention ratio of approximately 99.9% after 60 cycles at 10.0 C. Moreover, the discharge energy density is also improved due to the enhancement of discharge voltage platform. (C) 2017 Elsevier B.V. All rights reserved.
