Ni-MH batteries are widely used due to their rechargeable and environmentally friendly characteristics. With the wide application of Ni-MH batteries, the requirements for the capacity of Ni-MH batteries are getting higher and higher. Conventional Ni-MH rechargeable batteries are often unable to reach users due to their low capacity. Requirements for battery life. The Ni-MH rechargeable battery also cannot meet the needs of the market due to the low production efficiency due to the welding of the positive electrode collector plate during assembly.

Due to the electrical conductivity of the steel shells, the requirements for assembly operations are relatively high. If the operator does not install the battery in the center, it may lead to short circuit of the pole pieces or poor contact of the tabs, resulting in increased electrode resistance or even false connection, seriously affecting product quality. This requires a battery structure that reduces the difficulty of installing the battery cells and at the same time solves the problem of poor contact between the pole piece and the battery cap or steel case.
