Aluminum foil battery
1. Aluminum foil batteries significantly improve the consistency of battery pack use and significantly reduce the cost of battery packs. Such as:
Significantly reduce the increase of dynamic internal resistance of the cell.
Improve the consistency of the differential pressure of the battery pack.
Extend battery pack life.
Significantly reduce the cost of battery pack.
、
2. Aluminum foil battery cell improves the adhesive adhesion of active material and fluid collector, soft material, easy processing, and reduces the pole piece manufacturing cost. Such as:
Improving the adhesion of cathode materials and collectors using aqueous systems;
Improving adhesion of cathode materials and collectors at the nano- or sub-micron level;
Improving the adhesion of lithium titanate or other high-capacity cathode materials and collectors;
Improving the qualification rate of pole piece fabrication and reducing pole piece manufacturing cost.
After using carbon coated aluminum foil, the adhesion force of electrode wafer is increased from 10gf to 60gf (by 3M tape or Baguette method), and the adhesion force is significantly improved.
3. Aluminum foil battery reduces polarization, increases multiplier and gram capacity, and improves battery performance.
Such as partially reducing the proportion of adhesive in the active material and increasing the gram capacity;
Improving the electrical contact between the active material and the collector fluid;
Reducing polarization and improving power performance.
