Abstract

The invention discloses a secondary lithium battery which can effectively solve the problem of the exorbitant internal resistance of the existing secondary lithium battery. The secondary lithium battery comprises a negative terminal, a negative collecting ring, a rolled core, a positive collecting ring, a positive terminal, a cover plate and a casing, wherein the casing is provided with a accommodation cavity; the positive collecting ring, the rolled core and the negative collecting ring are successively connected from top to bottom in the accommodation cavity; the cover plate is arranged in the accommodation cavity on the negative collecting ring; the positive terminal is arranged on the bottom end of the casing; the positive terminal and the casing are manufactured as a whole; the positive terminal is connected with the positive collecting ring; the negative terminal is arranged on the cover plate on the top end of the casing; and the negative terminal is connected with the negativecollecting ring. The invention has the advantages that the whole product has smaller weight, and the positive terminal and the casing are manufactured as a whole, thus omitting the welding technologyand lowering the internal resistance of the battery and the production cost.

Description

technical field [0001] The invention relates to a secondary lithium battery. Background technique [0002] The positive end caps and shells of existing secondary lithium batteries are all made of nickel-plated iron, the positive base is made of aluminum, the negative base is made of copper, and the negative lug and negative current collector are made of nickel, so that the quality of the whole battery will decrease. It is relatively heavy, and because the materials of each component are different, it is very difficult to weld, which increases the internal resistance of the battery. Contents of the invention [0003] The object of the present invention is to provide a secondary lithium battery, which can effectively solve the problem of excessive internal resistance of the existing secondary lithium battery. [0004] In order to solve the above-mentioned technical problems, the present invention is achieved through the following technical solutions: a secondary lithium bat...
