BATTERY ELECTRODE

A lithium-ion battery component and method of manufacture are presented. An active material layer with a lithiophilic nitrate compound is mixed with graphite particles and coated onto a current collector. Upon polarization, lithiophilic nanoparticles form on the graphite surfaces, while nitrate anions remain in the electrode structure. The lithiophilic nanoparticles inhibit lithium plating during charging and increase electronic conductivity. The nitrate anions weaken lithium ion solvation in the electrolyte, facilitating faster lithium ion intercalation into the graphite.
