ã€China Aluminum Industry Network】1. Significantly enhance the consistency of the battery pack and dramatically reduce the number of battery cells used. For example: Heilongjiang Junhe Building Materials Technology Co., Ltd , https://www.junhejiancai.com
Dramatically lower the increase in internal resistance of individual battery cells;
Improve the pressure difference consistency across the entire battery pack;
Extend the overall lifespan of the battery system;
Substantially reduce the complexity and number of battery components.
2. Enhance the adhesion between active materials and current collectors, while lowering the cost of electrode manufacturing. Examples include:
Improve the bonding strength between cathode materials and current collectors using water-based systems;
Strengthen adhesion for nanometer or sub-micrometer cathode materials with current collectors;
Improve adhesion between high-capacity anode materials such as lithium titanate and their current collectors;
Increase the yield rate of electrode sheets and reduce production costs.
3. Reduce polarization, increase charge-discharge rates, and improve overall battery performance. For instance:
Partially reduce the binder content in active materials to boost specific capacity;
Enhance the electrical contact between active materials and current collectors;
Minimize polarization effects and improve power output capabilities.
4. Protect the current collector and prolong battery life. This can be achieved by:
Preventing corrosion and oxidation of the current collector;
Improving surface tension of the current collector for better coating performance;
Replacing costly etched foils with thinner, more cost-effective alternatives.
