Problems solved by technology

[0002] At present, the production process of the battery is relatively complicated. If the contact between the current collector and the positive electrode is uneven, it will easily lead to unstable discharge platform, low discharge capacity at high current, and failure of the battery discharge process.

Embodiment Construction

[0018] A battery cover set, comprising a positive pole cover and a positive pole post, and a liquid injection hole is arranged on the positive pole cover. A ring of bumps is arranged on the upper surface of the positive electrode cover along the outer circumference. The outer surface of the positive pole below the positive pole cover is provided with uneven lines. The uneven lines may be grid-like or corrugated.

[0019] The positive pole passes through the positive pole cap and is fixed on the positive pole cap through the glass body. The upper surface of the vitreous body is a horizontal plane.

Abstract

The invention relates to the technical field of battery productions, and especially relates to a battery cover set. The battery cover set comprises an anode cover and an anode column. The outer surface of the anode column below the anode cover is provided with rough and uneven lines. According to the invention, with the rough and uneven lines arranged on the anode column, the contact area between the anode column and a carbon pack is increased, and the fluidity of lithium ions is effectively improved. Therefore, the reactions between the anode and the cathode are more sufficient, the discharge voltage is stable, and fluctuation is not occured.

Description

technical field [0001] The invention relates to the technical field of battery production, in particular to a battery cover assembly. Background technique [0002] At present, the production process of the battery is relatively complicated. If the contact between the current collector and the positive electrode is uneven, it will easily lead to an unstable discharge platform, low discharge capacity at high currents, and failure of the battery discharge process. This is because during the discharge process, the positive and negative electrodes react to form a product that plugs the contact surface between the current collector and the positive electrode carbon. [0003] At present, the positive pole has a smooth surface, which is not conducive to the flow of ions, the reaction of the positive and negative poles is slow, and the discharge capacity is small. Contents of the invention [0004] The present invention provides a new lithium battery cover set aiming at the ab...
