NMC/NCA Batteries
A new energy vehicle battery pack manufacturer experienced swelling and sudden capacity drops in numerous NMC battery packs due to poor cell sealing, ultimately leading to vehicle recalls costing tens of millions. The company subsequently implemented automated leak testing equipment to conduct 100% inspection of each cell and module, completely eliminating inspection oversight risks.
