Abstract
Electrochemical performances of the isocubanite CuFeS tested as electrode material for Li-ion batteries have been investigated. A first discharge capacity of 860 mA h g shows a conversion process leading to LiS, copper and iron nanoparticles. Interestingly, a reversible capacity of 560 mA h g at 1.5 V is demonstrated with good cyclability up to 30 cycles.
摘要
已研究了作为锂离子电池电极材料测试的等轴硫铜铁矿CuFeS的电化学性能。首次放电容量为860 mA h/g，表明发生了导致LiS、铜和铁纳米颗粒的转化过程。有趣的是，在1.5 V时展示了560 mA h/g的可逆容量，并且在高达30次循环时具有良好的循环稳定性。
