4.Recommendations

This type of alloy powder is a low-temperature product with excellent high-power and low-temperature charge and discharge performance.

This type of alloy powder is suitable for the production of batteries that require high current and low temperature discharge.

★Because the alloy has excellent high-power characteristics, the alloy has a high hydrogen absorption and release platform, and attention should be paid to avoid gas or liquid leakage in the battery design.

Note: Due to different processes, the above test results and parameters are only a reference for the design of the final battery product.
