Abstract
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.
Claims7
An apparatus for continuously manufacturing battery cells, comprising:
- a rotary means for carrying a battery stack for continuous processing the battery stack;
- a cathode feeder having a cathode spool, a handler for handling a cathode layer from the cathode spool, a cutter for cutting the cathode layer at a pre-determined length, and a clamping means for clamping the cathode layer;
- a first separator feeder having a first separator spool, a handler for handling a separator layer from the first separator spool, and a clamping means for clamping the separator layer from the first separator spool;
- an anode feeder having a anode spool, a handler for handling an anode layer from the anode spool, a cutter for cutting the anode layer at a pre-determined length, and a clamping means for clamping the anode layer;
- a second separator feeder having a second separator spool, a handler for handling a separator layer from the second separator spool, and a clamping means for clamping the separator layer from the second separator spool;
- and
- a cutting device for cutting the battery stack at a pre-determined length to form a final battery stack.
