电池有时含有贵重或有毒物质（如镍、钴、铅、汞、镉）。但是，日本的小型电池的回收率和再利用率较低。我们以锂离子电池中的钴为研究对象，在日本进行了化学分析、问卷调查和流动分析。化学分析结果显示，无论是生产年份还是生产厂家，锂离子电池中的钴含量都在20%左右。消费者问卷调查的结果表明，70%或更多的小型电池在最终处理小型电子产品时没有被移除。调查还显示，对收集和回收小型充电电池的法律和制度的认可度约为30- 40%。物质流分析表明，2002-2010年期间，锂离子电池（钴）的生产和需求都有所增加。在此期间，废旧锂离子电池的收集率约为10%;未收集的电池被储存或通过焚烧和填埋作为城市固体废物处理。(C)2013爱思唯尔有限公司版权所有。
Batteries sometimes contain precious or toxic substances (e.g. nickel, cobalt, lead, mercury, cadmium). However, the collection and recycling rate of small batteries were low in Japan.We focus on cobalt in lithium ion (Li-ion) batteries and conduct chemical analysis, questioner survey and flow analysis in Japan.Results of chemical analysis showed that the concentration of cobalt in Li-ion batteries was around 20% regardless of the year manufactured or the manufacturer. As a result of the consumer questionnaire survey, it became clear that 70% or more of the small batteries are not being removed when small electronic products are finally disposed. The survey also revealed that recognition of the law and system for collection and recycling of small rechargeable batteries is approximately 30-40%. Substance flow analysis showed that both production and demand for Li-ion batteries (cobalt) have increased during 2002-2010. The collection rate for used Li-ion batteries was about 10% during this period; uncollected batteries were either stored or disposed through incineration and landfill as municipal solid waste.
