Cell would be heated up during formation, which improve the fluidity of electrolyte, strengthen the viscosity of electrolyte, with homogeneously spread of electrolyte, SEI would be formed easily, cycle life could be extended; Cooling compression could cool down the cell temperature quickly, under this format cell would be in good performance, low bulge rate and long cycle life, etc.

Solution adopts compression in horizontal way, clamping tools adopts server rod, pressure distributes in uniformity, pressure control deviation ≤10kgf.

Clamping tool for compression tray be heated by electricity, and the temperature could be flexibly adjusted, maximum temperature tolerance can reach 90°C.

Clamping tools are compatible for tabs on each side and tabs on same side, and realize quick changeover.
