目前我国手机总产量已超过20亿部,如果一部手机配一块锂离子电池边锋游戏,这些电池的平均寿命为3年,那么3年后,我们身边的废旧锂离子电池数量就可能达到数以百亿块。这还不包括笔记本电脑、照相机、充电宝等常用设备中所使用的锂离子电池。随着新能源汽车的日益普及,锂离子电池在新能源汽车上的应用又将带动锂离子电池的生产。从手机到电动自行车再到电动汽车,生活中的废旧锂离子电池越来越多,而资源却愈加紧张,环保要求日益严格,面对数以万计的废旧锂离子电池若处理不好,人们的身体健康将直接或间接地受到伤害。


手机锂离子电池用时间久了会出现鼓包现象,受外力后可能出现破损,电池中含有不稳定的电解质溶液,泄露会污染环境。其电解质六氟磷酸锂(LiPF6)在潮湿的空气中会分解生成有害物质,而碳酸酯类有机溶剂会对水、大气和土壤造成严重污染,严重危害生态系统。即使废锂电池没有发生破损现象,但如果与生活垃圾一起填埋,久而久之,渗出的重金属钴、铜等也会对环境构成潜在的污染。数据显示,1个20g的废旧手机锂电池可污染6 000m3的水资源、污染1km2的土地长达50年左右。可见,如果将数以百亿块的手机废电池随意和垃圾一起处置,对人类环境所造成的污染可想而知。
