【摘要】 通过测试LiFePO4在1.0mol/L的锂离子水溶液电解液中不同扫描速率下CV曲线,研究了LiFePO4在水溶液电解液中的电化学储锂性能。结果表明:Li+嵌入和脱出LiFePO4的扩散系数分别为9.97×10-15和1.22×10-14cm2/s,在水溶液中LiFePO4可以实现完全的嵌/脱锂,且具有非常好的嵌/脱锂可逆性和稳定性。证实了LiFePO4作为水溶液可充放电锂离子电池电极材料的可能性。更多还原

【Abstract】 The electrochemical storage lithium properties of LiFePO4 in an aqueous electrolyte were studied by testing the CV curves of LiFePO4 in a 1.0 mol/L Li+ aqueous electrolyte at various scan rates. The results show the diffusion coefficients of Li+ intercalation/deintercalation LiFePO4 body are 9.97×10-15 and 1.22×10-14cm2/s, respectively. The material can completely implement intercalation/deintercalation lithium and possess excellent reversibility and stability in an aqueous electrolyte. These indicate that the possibility of LiFePO4 used as an electrode material for aqueous rechargeable lithium-ion battery.更多还原
