The Heat Treatment Of Battery Contact

The heat treatment of battery contact is a crucial step in the battery manufacturing process, which is crucial for improving the performance, stability, and durability of battery contact. Battery contact is usually made of metal or alloy, and its microstructure, mechanical properties, and electrochemical performance can be changed through heat treatment to meet the requirements of the battery system.

The heat treatment of battery contact usually includes the following steps:

Annealing: Annealing is a heat treatment process that heats the battery to a certain temperature and then slowly cools it. This process can eliminate the internal and residual stresses generated by the material during the manufacturing process, improve its plasticity and toughness, and make it easier for subsequent processing and forming.

Quenching: Quenching is the process of heating a battery to a critical temperature and then rapidly cooling it. This process can form microstructures with high hardness and strength, improving the wear resistance and corrosion resistance of battery contacts. However, the quenched material is usually brittle, so subsequent tempering treatment is required.

Tempering: Tempering is the process of reheating the quenched battery to a lower temperature, holding it for a period of time, and then slowly cooling it. This process can eliminate the internal stress and brittleness generated during the quenching process, while maintaining a certain level of hardness and strength. The battery contact after tempering treatment usually has better mechanical and electrochemical properties.

Aging treatment: Aging treatment is a heat treatment process that involves long-term insulation, typically carried out at lower temperatures. This process can further improve the microstructure and performance of battery contact, eliminate residual stress and instability in the material, and enhance the long-term stability and durability of battery contact.
The heat treatment process for battery contact needs to be determined based on specific material types, sizes, and usage requirements. By using a reasonable heat treatment process, the performance of battery contact can be optimized, and the contact effect and current transmission efficiency between the battery and the battery system can be improved, thereby enhancing the overall performance and safety of the battery.

In addition, during the heat treatment process of battery contact, attention should also be paid to controlling parameters such as heating temperature, insulation time, and cooling speed to ensure the desired heat treatment effect is achieved. At the same time, strict inspection and testing of the battery contact after heat treatment is also necessary to ensure that its quality and performance meet the requirements.
