    • To provide a method for treating nonaqueous solvent type cells, in particular, a method by which lithium cells can be treated and resources can be recovered in safe and in a good efficiency, a method for recovering resources of lithium cells comprises the steps of cutting or boring a lithium cell comprised of at least a negative electrode active material, a separator, a positive electrode active material, an electrolyte solution (electrolytic solution), a collector and a cell casing, in an ignition preventing means; washing the lithium cell thus opened, with an organic solvent to recover the electrolytic solution; reacting lithium with a reacting agent to recover lithium in the form of lithium hydroxide or a lithium salt; carrying out filtration to recover the separator, the collector and a positive electrode material comprising the positive electrode active material; and carrying out distillation to recover the organic solvent. This makes it possible to safely treat lithium cells having been used up, containing organic solvents and metallic lithium, and efficiently recover the resources. This also makes it easy to recycle lithium cells.
    • 为了提供一种处理非水溶剂型电池的方法,特别是可以安全地且高效率地回收锂电池的方法,回收锂电池的资源的方法包括以下步骤:切割或 在防点火装置中使由至少负极活性物质,隔膜,正极活性物质,电解液(电解液),集电体和电池壳体构成的锂电池镗孔; 用有机溶剂洗涤如此打开的锂电池以回收电解液; 使锂与反应剂反应以回收氢氧化锂或锂盐形式的锂; 进行过滤以回收分离器,集电体和包含正极活性物质的正极材料; 并进行蒸馏以回收有机溶剂。 这使得可以安全地处理已经被使用的锂电池,含有有机溶剂和金属锂,并有效地回收资源。 这也使回收锂电池变得容易。
