Modified aluminum foil
The use of functional coatings for surface treatment of battery collectors is a groundbreaking technological innovation. Modified aluminum foil is a functional layer coated with multiple or one of the conductive materials on the surface of aluminum foil, forming an excellent two-dimensional or multi-dimensional conductive network structure. Through theoretical simulation calculations and multiple experiments, continuous exploration is carried out to find the optimal ratio structure and process conditions. Compared with modified aluminum foil on the market, this process can make the surface coating thickness thinner, the coating resistance lower, and the adhesion ability stronger, effectively improving the electrochemical performance and product stability of lithium batteries, and reducing production and usage costs.
Main purpose:
◎ Power/energy storage lithium-ion batteries (LFP, LMFP, LMO, NCM, NCA, LNM, LTO)
3C type lithium-ion batteries (LCO, LMO)
◎ Supercapacitors
Lithium ion capacitors
◎ Water based lithium-ion batteries
◎ Alkaline battery
Features:
Improve the surface tension of aluminum foil and increase the adhesion performance between aluminum foil and active substances
Reduce the amount of adhesive added to the electrode, improve the energy density of the battery, and reduce the manufacturing cost of the electrode piece
◎ Protect the current collector to prevent corrosion and oxidation on the surface of aluminum foil
◎ Reduce interface resistance and reduce battery internal resistance
Reduce polarization, improve battery rate charging and discharging performance, and maximize the capacity of active substances
◎ Reduce battery heat generation and improve battery safety performance
Improve product stability and consistency; Improve the production qualification rate and battery pack matching rate of individual batteries, improve the consistency and cycling service life of individual batteries and battery packs, and reduce production costs
