Preparation and electrochemical properties of nano amorphous Tin-based composite oxide

采用机械球磨的方法制得纳米非晶态的锡基复合氧化物,并对其进行电化学性能检测.研究表明：掺B、P、Al、Ca制备的锡基复合氧化物首次放电比容量大于仅掺B、P制备的锡基复合氧化物首次放电比容量,大于掺B、P、Al制备的锡基复合氧化物首次放电比容量;在0.005～1.2 V电压区间下,掺B、P、Al、Ca制备的锡基复合氧化物循环性能大于掺B、P、Al制备的锡基复合氧化物循环性能,大于仅掺B、P制备的锡基复合氧化物循环性能;电压区间能够影响锡基复合氧化物的循环性能,增大电压区间,循环性能下降.

Nano Tin-based amorphous composite oxide was obtained by mechanical milling method. Its electrochemical performance was tested. Studies show that： The initial discharge capacity of doped B, P, AI, Ca Tin-based composite oxide is higher than the initial discharge capacity of only doped B, P Tin-based composite oxide, and also higher than the initial discharge capacity of doped with B, P, AI Ti-based composite oxide. In the 0.005-1.2 V voltage range, the cycle performance of doped B, P, AI, Ca Tin-based composite oxide was higher than the cycle performance of doped B, P, AI Tin-based composite oxide, and higher than the cycle performance of only doped B, P prepared tin-based mixed oxides. The performance of the cycle was affected by the voltage range of tin-based composite oxide; the voltage range was increased, while the cycle performance was decreased.
