| 摘 要： | 通过热处理法和溶解法,对废旧动力锂离子电池电极活性物质磷酸铁锂(LiFePO4)进行处理.与700 t热处理再生的材料相比较,经350℃热处理的活性物质在结晶度、首次充放电和循环稳定性等方面表现较好。经350℃热处理的LiFePO4,以0.2 C在2.0~4.2 V循环,首次放电比容量达120 mAh/g,第40次循环的比容量为130 mAh/g,库仑效率保持在99%。

| Abstract: | The waste electrode materials were investigated by the heat treatment method and solvent method for recycling.Compared with the regenerated materials calcined at 700℃,the active materials treated at 350℃exhibited better electrochemical performance in crystallinity,initial charge-discharge and cycle stability.The initial specific discharge capacity of recycled LiFeP04 was 120 mAh/g calcined at 350℃and reached 130 mAh/g after 40 cycles at 0.2 C in 2.0-4.2 V and the Coulombic efficiency was still 99%. |
