Embodiment 1

[0012] Embodiment 1: Perform performance comparison with Cd-Ni40Ah storage battery. Make three kinds of storage batteries, one type of negative electrode group uses sintered cadmium electrode sheets, the second type of negative electrode group uses foam type cadmium electrode sheets, and the third type of negative electrode group uses mixed electrode sheets, sintered type and foam type each account for half. During production, the two electrode sheets are spaced apart from each other, that is, cross-stacked. The three batteries all use the same positive electrode and battery structure, and perform performance comparisons after formation. The comparison results are shown in Table 1:

[0013] Table I:

[0014] performance

[0015] It can be seen from Table 1 that the comprehensive performance of the battery is good when the mixed electrode sheet is used, and its various indicators are between the performances of the two batteries using the same electrode sheet.

Embodiment 2

[0016] Embodiment 2: Perform performance comparison with Cd-Ni40Ah storage battery. Make three kinds of storage batteries, one type of negative electrode group uses sintered cadmium electrode sheets all, the second type of negative electrode group uses all bonded cadmium electrode sheets, and the third type of negative electrode group uses mixed electrode sheets, sintered type and bonded type each account for half , When the battery is made, the two electrode sheets are spaced apart from each other, that is, cross-stacked. The three batteries all use the same positive electrode group and battery structure, and perform performance comparison after formation. The comparison results are shown in Table 2.

Embodiment 3

[0019] Embodiment 3: Performance comparison with MH-Ni27Ah storage battery. Make three kinds of batteries, one negative electrode group uses foam hydrogen storage electrode sheets, the second negative electrode group uses bonded electrode sheets, and the third negative electrode group uses mixed electrode sheets, foam type and bonded type each account for half , When the battery is made, the two electrode sheets are spaced apart from each other, that is, cross-stacked. All three batteries use the same positive electrode and battery structure, and perform performance comparisons after formation. The comparison results are shown in Table 3.

Abstract

This invention discloses a battery, in which, a positive set and a negative set are set in a shell and at least one set contains two or more than two kinds of pole plates in different structures to increase the comprehensive ability of the battery,

Description

technical field [0001] The invention relates to a storage battery. Background technique [0002] In various types of batteries, electrodes with different structures have different characteristics and advantages, and the performance of the produced batteries is quite different, such as nickel electrodes in MH-Ni, Cd-Ni, Zn-Ni and other batteries. , There are several structural forms, such as sintered type (sintered matrix), foam type (nickel foam, copper foam, etc. as the matrix), bonded type (steel strip, nickel strip, etc. substrate), etc. Cd electrodes in nickel-cadmium batteries are also divided into sintered, foamed, bonded and other types. Each type of electrode has its own advantages and disadvantages in terms of performance and cost. Sintered electrodes have good power performance and high and low temperature performance, but low specific capacity and high cost; foam electrodes have high specific capacity and low cost, but poor power performance, and bonded electro...
