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.
