Problems solved by technology

After many dissections, most of the current batteries are terminated in advance. According to the ratio of plate height to width, generally (20-30)% of the active materials are not fully utilized, which seriously wastes the earth's resources.

Embodiment Construction

[0025] In order to complete the "stereo-diagonal" setting of the positive and negative poles of the single battery, the following must be done: 1). Alternate stacks of negative poles, such as Figure 4 2) The positive and negative poles of the single battery are arranged at the three-dimensional diagonal positions of the single battery, such as Figure 4 , 5 As shown, only the secondary diagonal design can ensure that ①. The current flowing through each plate in the single battery is equal; ②. The current flowing through the active material at any point on each plate is equal during charging and discharging; ③ .Satisfying 1 and 2, the electrochemical reaction intensity of the active material at each point of the inner plate of the single battery is basically equal, and all active materials are fully utilized; 3) The general deviation error of the "diagonal" point is not greater than 1 / of the length of the bus bar 4. It will have a good effect; 4) The shell must meet the req...

Abstract

The present invention belongs to the technical field of improvement technology of laminated (including tubular) acidic or alkaline storage batteries widely used in the energy field; aims to solve the problem that for a long time, when dissecting these storage batteries after their life expirations, 20-30% of active substances at the bottom of the anodes have not been fully utilized, or the lives of these storage batteries are terminated in advance as a result of the sulfation. The worldwide problem is caused by the unequal current strength at each point on polar plates in a single battery generated during the charging and the discharging, and is solved by the principle of two-terminal network. The scheme of the present invention is to adjust the distribution of the internal resistance by adjusting the positions of the anode and the cathode in a single battery, and solve the above problem effectively by adopting a stereo diagonal distribution. The technology is applicable to acidic or alkaline secondary batteries with various sizes.

Description

technical field [0001] The present invention is the improvement technology of laminated acid and laminated alkaline accumulator widely used in the field of energy, and it relates to the polar plate (sheet) shape, stacked plate (sheet) mode of acidic and alkaline secondary battery, the monomer The location of the positive and negative poles of the battery and the matching casing (plastic). Hereinafter collectively referred to as laminated batteries. Background technique [0002] At present, two major types of secondary batteries, acidic and alkaline, are used in almost all fields, and they appear in the market in the form of laminated sheets and winding types. The present invention is only valid for laminated batteries. In the long-term use of batteries, human beings have found that many large-capacity batteries are especially like forklifts, UPS, submarines, and communications. When the batteries used are dissected at the end of their life, it is found that the upper part ...
