Abstract: 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.

Abstract translation: 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。

Abstract: A rechargeable lithium-ion (Li-ion) battery employs a low temperature approach to battery manufacturing that forms charge material from kinetic energy of high velocity particles impelled into an aggregation such that bombardment of the particles against other particles in the aggregation forms a charge conveying structure. High velocity bombardment from a carrier gas nozzle accumulates an active charge material in a layered arrangement for the finished battery. Preparation of the particles, such as by ball milling or spraydrying, arranges particle agglomerations. The particle agglomerations, when impelled against other agglomerations or a current collector, forms a layer of cathodic, anodic or electrolytic battery material. The metallic binder conveys charge for mitigating or eliminating a need for a planar current collector underlying the sprayed layer. The resulting layers are suitable for battery operation, and are manufactured in an absence of any solvent drying or disposal.
