摘要Novel LiFePO4/Ti3C2 composite (LFP/TC) cathodes have been prepared via a simple wet mixing method followed by a heat treatment at 400 A degrees C. Ti3C2 nanosheets bridge the LiFePO4 nanoparticles to form an integrated conductive network via the "plane-to-point" conducting mode. This conductive network acts as short pathways for the diffusion of both lithium ion and electron in the composite cathode. Thus, the electronic and ionic conductivities are simultaneously enhanced, leading to the improved electrochemical properties of LFP/TC composites. Thereinto, the LFP/TC composite with 2 wt% Ti3C2 (LFP/TC2) delivers the highest initial discharge capacity of 159 mAh g(-1) at 0.1 C as well as the best rate performance with a high reversible capacity of 86 mAh g(-1) at 5 C. Meanwhile, the LFP/TC2 composite also holds the superior capacity retention of 96% at 1 C after 100 cycles. The results demonstrate that LFP/TC composite has promising practical applications as the cathode material in the high-power lithium-ion batteries.; Novel LiFePO4/Ti3C2 composite (LFP/TC) cathodes have been prepared via a simple wet mixing method followed by a heat treatment at 400 A degrees C.
