Embodiment Construction

[0025] The present invention will be described in detail below in conjunction with accompanying drawing:

[0026] figure 1 Shown in is a schematic half-section of an existing battery. The battery shown therein includes three parts: a battery core 4, a battery case 5, and a battery cover 6. The positive pole tab 7 drawn from the battery core 4 is connected to the battery end cover 6 to act as the positive pole of the battery, and the negative pole is drawn out. The terminal 8 is directly connected to the battery case 5, and the battery case 5 serves as the negative pole of the battery. The battery core 4 is formed by stacking the positive electrode sheet 1, the separator 3, the negative electrode sheet 2, and the insulating roll 9 in sequence, and then winding them. The positive electrode tab 7 is connected to one end of the positive electrode sheet 1, and the negative electrode tab 10 is connected to the negative electrode sheet. 3 on the same end.

Abstract

The invention relates to a multipole plate terminal ear storage battery which comprises a battery cell (4) composed of a positive plate (1), a negative plate (2), a membrane (3) and blanket insulation (9) in a winding way; wherein, the positive plate (1) comprises a plurality of aluminum foil made base pole plates; the negative plate (2) includes a plurality of clutch gold made base pole plates; the number of the aluminum foil made base pole plates is equivalent to the number of the corresponding clutch gold made base pole plates. The battery can realize equivalent capacity as well as rapid charge and discharge, prolongs the service life of the battery, reduces the failure rate of the battery and meanwhile effectively reduces the internal resistance of the battery.

Description

(1) Technical field [0001] The invention relates to a battery with multi-pole tabs and terminal tabs, in particular to a storage battery with multi-pole tabs, equal area and tabs. (2) Background technology [0002] At present, the comprehensive electrical properties of cylindrical lithium-ion secondary batteries are excellent, but in terms of the performance of their use, the main reason is that the charge and discharge speed is too slow, the battery is damaged during use, and the service life is short. [0003] With the rapid development of electronics industry, information industry, energy saving and environmental protection, people have higher and higher requirements for power supplies of various electrical appliances. As a high-energy power source, lithium-ion secondary batteries are used in various occasions, especially as power batteries, and their electrical properties are extremely important. [0004] Therefore, people began to study how to improve the performance o...
