The invention relates to a high-efficiency and high-rate lithium battery structure, and is used for solving the problems that since a general lithium battery pole ear is used for conducting electric energy by welded pole columns, a welding process is difficult, the electrical conduction efficiency of a lithium battery is affected by welding spots and the discharging rate of the lithium battery is limited. The battery structure comprises a seal cover; electricity-taking pole ears are arranged below the seal cover, and the front end part of each electricity-taking pole ear passes through the seal cover and is located on the surface of the seal cover; each electricity-taking pole ear is wrapped with an insulating layer, and the front end part of each electricity-taking pole ear is exposed on the upper surface of the insulating layer located on the seal cover to form an external terminal. The battery structure has the advantages that the electricity-taking pole ears adopt integral design, the problem that a conventional lithium battery has process bottlenecks for welding the pole ears and the pole columns, the discharge rate of the lithium battery is increased, and the resistance and heat radiation conditions caused by the welding points during large current discharge are reduced. The electricity-taking pole ears are directly wrapped by the insulating layers of the pole ears, and the insulating layers of the pole ears have good sealing and insulation performance with the battery seal cover. The lithium battery structure has simple whole structure, reduces lithium battery manufacturing process, shortens the production time and reduces material costs.
