Continuous prismatic cell stacking system and method

摘要

A continuous prismatic cell stacking system and method is disclosed. The system comprises: (a) devices on the system to supply a separator layer, a cathode layer, and an anode layer; and (b) one cutter on the frame for cathode layer and anode layer; and (c) conveyer system to convey the stacked cell. The conveyer system comprises a rotary disc and a transfer belt. The said rotary disc is round shape, or multi-equilateral shape, or track & field shape.

1. A method of forming a battery stack comprising a plurality of stacked prismatic cell layers, comprising:
rotating a rotary disc from a first position to a plurality of stacking stations,
wherein the rotary disc is operable to make a complete rotation in a single direction,wherein the rotary disk operates to support at least one of the plurality of prismatic cell layers,wherein the plurality of prismatic cell layers comprises at least one cut prismatic cell layer and at least one continuous separator layer; collecting a first cut prismatic cell layer or a first continuous separator layer onto the rotary disc to form a first battery stack; collecting the first cut prismatic cell layer, the first continuous separator layer, a second cut prismatic cell layer, or a second continuous separator layer onto the first battery stack to form a second battery stack; collecting the first cut prismatic cell layer, the first continuous separator layer, the second cut prismatic cell layer, or the second continuous separator layer onto the second battery stack to form a third battery stack,
wherein the first cut prismatic cell layer and the second cut prismatic cell layer are selected from an anode layer and a cathode layer, and rotating the rotary disc in the single direction such that the third battery stack is transported to or past the first position.
