- 锂电池:锂电池是指用锂作负极活性物质的化学电池,常用高氯酸锂或溴化锂为电解质,锂的标准电极电位最负 (-3.03V),在金属中比重最轻,反应活泼性最高,因而锂电池的电动势和比能量很高,是一种重要的高能电池,其单位重量产生的有效电能量为铅蓄电池的10~12倍,且放电电流十分平稳。锂电池的正极活性物质有氧化物、硫化物、卤化物、卤素、含氧酸盐等无机电极材料,如二氧化锰、二氧化硫、硫化铜、铬酸银、聚氟化碳、亚硫酰氯、碘等; 也可以电子导电聚合物作正极材料,如聚乙炔、聚吡咯、聚噻吩、聚咔唑等,又称为聚合物电池。锂电池的电解质为非水溶液、固体和熔融盐。非水溶液电解质由有机溶剂或非水无机溶剂加入无机盐组成,采用的有机溶剂主要有碳酸丙烯酯、二甲基丙酰胺、乙腈、γ-丁内酯等;非水无机溶剂有亚硫酰氯,液体二氧化硫等。无机盐有高氯酸锂、氯化铝锂、氟硼酸锂、溴化锂等。因锂和水接触立即发生激烈反应,所以不仅电解质不能采用水溶液,而且全部材料和零部件均需严格脱水,并可靠密封。锂电池为一次电池,产品有多种形状和规格,如圆筒型、钮扣型、插头型等,在通讯、照相机、电子表、计算器、心脏起搏器及其他电子器件中得到广泛应用。这种电池的特点为高电压、高电流密度,可在高温下使用,不漏液,自放电小,使用寿命长等,最近已开发用于闪光灯内的高贮能电池,负
