Abstract

The invention provides a battery and a battery manufacturing method, the battery comprises: a shell, wherein the shell is internally provided with an accommodating cavity, the accommodating cavity isfilled with an electrode slice, a diaphragm and an electrolyte, the shell is provided with a first end and a second end which are oppositely arranged, the first end of the shell is provided with a first open hole, the second end of the shell is provided with a second open hole, and the first open hole and the second open hole communicate the containing cavity with the outer space of the shell; andtwo plugging pieces which are arranged at the first end of the shell and the second end of the shell in a one-to-one correspondence mode so as to plug the first open hole and the second open hole through the two plugging pieces. The battery provided by the invention solves the problem of poor battery performance caused by insufficient electrolyte filling in the prior art.

Description

technical field [0001] The invention relates to the field of batteries, in particular to a battery and a method for manufacturing the battery. Background technique [0002] The commonly used structure of batteries in the prior art is to process a hole at one end of the battery casing. During the battery production process, the cavity in the battery is evacuated through the hole, and then the electrolyte is supplied to the battery through the hole. The battery produced by this structural design and liquid injection method often has the problem of insufficient electrolyte coverage inside, resulting in the electrode sheet not being effectively wetted and affecting the performance of the battery. Contents of the invention [0003] The main purpose of the present invention is to provide a battery and a battery manufacturing method to solve the problem of poor battery performance caused by insufficient electrolyte perfusion in the prior art. [0004] In order to achieve the abo...
