China Aluminum Industry Network 1. Significantly enhance the consistency of the battery pack and drastically reduce the complexity of the battery composition. For example:
Dramatically minimize the increase in internal resistance of individual cells;
Improve the pressure differential uniformity across the battery pack;
Extend the overall lifespan of the battery system;
Substantially simplify the battery structure and reduce material usage.
2. Enhance the adhesion between active materials and current collectors, while lowering the cost of electrode production. For instance:
Improve adhesion between cathode materials and collectors using water-based systems;
Strengthen the bonding between nano or sub-micron cathode materials and current collectors;
Enhance the adhesion of high-capacity anode materials like lithium titanate with the current collector;
Increase the yield rate of electrode sheets and reduce manufacturing costs.
3. Reduce polarization, improve charge/discharge rates, and boost battery performance. Examples include:
Partially reduce the binder content in the active material to increase specific capacity;
Improve electrical contact between active materials and current collectors;
Minimize polarization effects to enhance power output and efficiency.
4. Protect the current collector and prolong battery life. For example:
Prevent corrosion and oxidation of the current collector;
Improve surface tension of the collector for better coating performance;
Enable the use of less expensive foils or thinner standard foils as alternatives.
These advancements not only improve the performance and reliability of batteries but also contribute to more sustainable and cost-effective manufacturing processes in the energy storage industry.
