废铅酸蓄电池的回收利用和管理对策

铅酸蓄电池是目前世界上各类电池中生产量最大,使用途径最广的一种电池,回收利用和管理铅酸蓄电池是环境保护领域中一项重要工作.废铅酸蓄电池在拆解过程中产生许多废物,如处理不当,对环境危害很大.如处理得当,则会提取再生铅,使之再利用,变废为宝.文章从废铅酸蓄电池的危害及其处理现状,提出如何回收利用,如何加强环境管理,为政府部门决策提供建议.     

从废旧锌锰电池中回收锌和锰的工艺研究

废旧锌锰干电池经过剖开、焙烧处理，去除汞和碳粉，再用硫酸浸取，滤液采用沉淀法分离锌和锰。锌和锰的回收率分别为94．5％和93．6％。     

Multi-level energy analysis of emerging technologies: a case study in new materials for lithium ion batteries

A range of new nanomaterials to replace the active materials in lithium ion batteries are currently being studied and employed in an attempt to overcome various performance limitations of previous technologies. Nanomaterial production and manufacturing techniques appear to fit into a general trend towards more energy intensive production methods for high-tech goods. This does not necessarily imply an increase in lifecycle energy use; artefacts that consume or transform energy during use could possibly regain this increased initial input via increased efficiency in use. In particular, this paper highlights that larger gains could be possible if the artefact in question allows a given service to be provided via an alternative and more efficient system entirely.The lifecycle energy efficiencies of lithium ion batteries constructed from several new advanced materials are analysed with several different system boundaries. Although nanomaterials require more energy input to produce, the implications of nanomaterials for energy flows in the use phase (i.e. driving), and higher levels such as the architecture of future transport fuel production systems are much larger in magnitude than the initial lifecycle inputs for producing the materials in question.     

锂离子电池替代铅蓄电池的环境风险对比分析与思考

目前中国市场上使用的蓄电池主要为锂离子电池和铅蓄电池,这两种电池在组成材料、技术成熟度、价格水平、生产使用过程及再利用过程等方面等皆不相同。通过对比分析两种蓄电池环境风险,可以发现锂离子电池和铅蓄电池各自存在优缺点,要"取代"或"淘汰"铅蓄电池是不全面和不客观的,目前比较切合实际的是实现两者的取长补短、优势互补和共同发展。
