摘要： Cathode material from exhausted lithium ion batteries are dissolved in a solution for extracting the useful elements Co (cobalt), Ni (nickel), Al (Aluminum) and Mn (manganese) to produce active cathode materials for new batteries. The solution includes compounds of desirable materials such as cobalt, nickel, aluminum and manganese dissolved as compounds from the exhausted cathode material of spent cells. Depending on a desired proportion, or ratio, of the desired materials, raw materials are added to the solution to achieve the desired ratio of the commingled compounds for the recycled cathode material for new cells. The desired materials precipitate out of solution without extensive heating or separation of the desired materials into individual compounds or elements. The resulting active cathode material has the predetermined ratio for use in new cells, and avoids high heat typically required to separate the useful elements because the desired materials remain commingled in solution.
摘要翻译：将从耗尽的锂离子电池的阴极材料溶解在用于提取有用元素Co（钴），Ni（镍），Al（铝）和Mn（锰）的溶液中以产生用于新电池的活性阴极材料。该溶液包括从废电池的耗尽的正极材料中作为化合物溶解的所需材料如钴，镍，铝和锰的化合物。根据所需材料的所需比例或比例，将原料加入到溶液中以获得用于新电池的再循环阴极材料的混合化合物的所需比例。所需的材料从溶液中沉淀出来，而不需要大量加热或将所需材料分离成单独的化合物或元素。所得到的活性阴极材料具有用于新电池的预定比例，并且避免了分离有用元素所需的高热量，因为所需材料保持混合在溶液中。

摘要： A recycling and synthesis of charge material for secondary batteries generates single-crystal charge materials for producing batteries with greater charge cycle longevity. Charge material particles undergo a heating for fusing or enhancing grain boundaries between polycrystalline particles. The resulting, more well-defined grain boundaries are easily etched by a relatively weak mineral acid solution. The acid solution removes material at the grain boundaries to separate secondary particles into primary particles along the grain boundaries. The resulting single crystal (monocrystalline) charge material particles are washed and filtered, and typically re-sintered to accommodate any needed lithium (lithium carbonate), and result in a charge material with larger surface area, higher lithium diffusivity and lower cation ordering.
