AI Technical Summary
In existing lithium-ion batteries, the positive electrode lithium replenishment material continues to decompose and generate oxygen during the later charging process, leading to battery performance degradation and safety hazards. Existing solutions have not completely solved this problem.
Using metal oxides containing oxygen defects, organic compounds carrying groups that can react with oxygen, and organic compounds carrying groups that inhibit oxygen production as electrolyte additives, the overall properties of the battery are improved and safety hazards are reduced by consuming or inhibiting oxygen generation through physical adsorption and chemical reactions.
It effectively consumes the oxygen generated by the positive electrode lithium supplementation additive, improves the overall performance of the battery, reduces the safety hazards of battery use, and makes the battery more widely used.
