Product features:

Reduce battery internal resistance: Aluminum foil has excellent conductivity, which can reduce the resistance of current inside the battery, thereby improving the charging and discharging efficiency of the battery.

Improving battery charging and discharging efficiency: Due to the low internal resistance of aluminum foil, the energy loss of the battery during charging and discharging is reduced, thereby improving the charging and discharging efficiency of the battery.

Extending battery life: By optimizing the material and structure of the current collector, the battery life can be extended. The stability and corrosion resistance of aluminum foil help maintain the performance and lifespan of batteries.

Product Introduction: Battery aluminum foil is a type of aluminum rolled material, mainly used as the positive electrode current collector for lithium-ion batteries. It needs to have high conductivity, corrosion resistance, good toughness and stiffness, as well as easy processing and shaping characteristics. Aluminum foil serves as a structural component for collecting current in lithium batteries, collecting and conducting the current generated by the active materials of the battery to the external circuit, achieving the conversion of chemical energy into electrical energy.
