摘要
研究了以聚4 - 乙烯吡啶为基体所得碳材料作为锂离子二次电池负极的电化学性能。在低温范围( < 1 000 ℃) ,热处理温度较高时,碳材料的可逆储锂容量下降,充电曲线降低。在基体材料中引入二乙烯基苯后,能有效地引入微孔结构,使碳材料的可逆容量随二乙烯基苯加入量的增加而增加,所得结果达600 m Ah/g 。
Electrochemical properties of carbon anode based on poly(4-vinyl pyridine)for lithium ion secondary battery were studied.In the low temperature range(<1?000℃),the higher heat-treatment temperature would result in the decrease of reversible lithium storage capacity and the lowering of charging curves.Micropores could be introduced effectively when divinyl benzene was incorporated into the based polymer.Reversible capacity increased with the amount of the added divinyl benzene and its highest value could be up to 600mAh/g
