The mold cavity of lithium battery separator is prone to wear and tear due to thin film stretching. The hardness of the mold cavity treated with traditional nitriding is low (HRC55-58), and the thickness deviation of the separator increases after wear, resulting in unstable internal resistance of the battery. The service life of the mold is only 10000-20000 cycles.
The Daokedao laser cladding equipment uses wear-resistant and anti adhesive alloy powder to deposit a dense coating on the surface of the mold cavity, with a hardness of HRC63-66 and a wear resistance three times that of nitriding treatment. The friction coefficient of the cladding layer is as low as 0.12, effectively reducing film adhesion and increasing the qualification rate of the diaphragm by 12%.
The service life of the repaired mold has been extended to 40000 to 50000 mold cycles, the consistency of lithium battery separator thickness has been improved by 20%, and the repair cost is only one-third of that of the new mold. After adopting this technology, a certain lithium battery company reduced the cost of mold replacement by 60%, which helped upgrade battery performance.
