Electrode column type dynamic battery

Abstract

The invention discloses an electrode column type dynamic battery which comprises a battery body, wherein the battery body is composed of a battery core body, a positive pole column, a negative pole column and an anti-explosion valve; the battery core body is provided with fixing pieces; the positive pole column and the negative pole column are respectively composed of a base and screws arranged on the base; the positive pole column and the negative pole column are connected with the fixing pieces through the bases; the anti-explosion valve is connected with the fixing pieces; the base connected with the fixing pieces is provided with a bracket gasket; the bracket gasket wraps on the outer surface of the base and is parallel and level to the bottoms of the screws; the bracket gasket is connected with a fixing bracket which is provided with a spacing groove I, a spacing groove II and a through hole; and the screw of the positive pole column stretches out of the spacing groove I, the screw of the negative pole column stretches out of the spacing groove II, and the anti-explosion valve stretches out of the through hole. Through the actions of the fixing pieces, the bracket gasket and the fixing bracket, the electrode can not rotate when the dynamic battery is used, thereby ensuring the safety and stability of the dynamic battery use process, and the installation and disassembly are convenient.

Description

technical field [0001] The invention relates to the field of batteries, in particular to an electrode column type power battery. Background technique [0002] SGL Carbon Co., Ltd. applied for the patent number "200410100589.9" in 2004, and the invention patent named "threaded connection of carbon and / or graphite electrode columns" mainly solves the problem of avoiding carbon and / or graphite electrodes when the battery is used. Risk of loosening or unscrewing from the battery cell. Such as figure 1 and figure 2 As shown, in this patent, the electrode and the battery body adopt a threaded connection structure, that is, the electrode is connected into an electrode column through a carbon connection pin structure. In the carbon connecting pin structure disclosed in this patent, at least one part has a wedge slope at the bottom of its threaded ring; when the threaded connecting elements are screwed together, the threaded ring crest of one part is adjacent to the wedged slope ...

AI Technical Summary

Problems solved by technology

Although the threaded connection structure adopted in this patent has a simple structure, it can prevent the electrodes from loosening during the battery rotation process. However, the threaded structure is prone to slipping after long-term use, which will eventually cause the electrodes to loosen and affect the safety of the power battery. Performance and stability, further affecting the normal use of the battery
