为了探究磷酸铁锂回收料对锂离子电池性能的影响，以石墨为负极材料，以磷酸铁锂（LFP）(A组LFP为常规料，B组LFP为回收料)为正极材料，通过叠片工艺，制成小软包电池进行验证和评估，并通过制备工艺及电化学测试等对比磷酸铁锂常规料和回收料的加工性能、倍率充放电性能、直流内阻（DCR）、高低温放电以及不同温度的循环性能。结果表明：磷酸铁锂回收料的加工性能与常规料相差不大，但浆料稳定性较差；在全电体系中，磷酸铁锂回收料制备的电池在0.2 C倍率下的比容量比常规料低8.23 mAh/g；在短期电性能中，磷酸铁锂回收料制备的电池DCR较好，高低温性能和不同倍率放电性能与常规料制备的电池相差不大，但不同倍率充电性能较差；在长期电性能中，磷酸铁锂回收料制备的电池在常温25℃循环1 000次的容量保持率比常规料低1.98%，在高温45℃循环1 200次的容量保持率比常规料低4.39%。

To investigate the influence of recycled lithium iron phosphate(LFP) materials on the performance of lithium-ion batteries, graphite was used as the anode material, and LFP was adopted as the cathode material(Group A used conventional LFP, while Group B used recycled LFP). Small pouch batteries were fabricated via the lamination process for verification and evaluation. The processability, rate charge-discharge performance, direct current resistance(DCR), high-low temperature discharge performance, and cycle performance at different temperatures of conventional LFP and recycled LFP were compared through preparation processes and electrochemical tests. The results indicate that: the processability of recycled LFP is comparable to that of conventional LFP, but the slurry stability is relatively poor; in the full-cell system, the specific capacity(at 0.2 C) of the battery prepared with recycled LFP is 8.23 mAh/g lower than that of the battery with conventional LFP; in terms of short-term electrical performance, the battery made from recycled LFP shows better DCR, and its high-low temperature performance is not significantly different from that of the battery with conventional LFP, yet its rate discharge performance is inferior; for long-term electrical performance, the capacity retention rate of the battery prepared with recycled LFP is 1.98% lower than that of the battery with conventional LFP after 1 000 cycles at room temperature(25 ℃), and 4.39% lower after 1 200 cycles at high temperature(45 ℃).
