Four-electrode lithium battery structure

Abstract

The invention relates to a four-electrode lithium battery structure. The four-electrode lithium battery structure comprises two dual-electrode positive electrode plates, two dual-electrode negative electrode plates and a plurality of diaphragms, wherein the plurality of diaphragms are arranged between the dual-electrode positive electrode plates and the dual-electrode negative electrode plates atintervals, the dual-electrode positive electrode plates of which positive electrodes and negative electrodes are staggered, the diaphragms and the dual-electrode negative electrode plates are laminated to form a battery cell of a lithium battery, the four-electrode lithium battery structure also comprises a PP tube, and the PP tube is arranged at one corner of the lithium battery and is hermetically connected with external package. Each dual-electrode positive electrode plate comprises two positive electrodes arranged at outer sides of two ends of the positive electrode plate, each dual-electrode negative electrode plate comprises two negative electrodes arranged at outer sides of two ends of the negative electrode plate, a 90-degree included angle between the positive electrodes and the negative electrodes is formed, the positive electrodes and the negative electrodes are respectively exposed out of four ends of the lithium battery, a plurality of through holes are respectively formedin the positive electrode plate and the negative electrode plate, and the diameters of the through holes are smaller than 5 micrometers. The four-electrode lithium battery structure is particularly and suitably used in rapid-charge and rapid-discharge new energy automobile, is high in charge-discharge efficiency and stable and reliable in performance.

Description

technical field [0001] The invention relates to the field of battery manufacturing, in particular to a four-electrode lithium battery structure. Background technique [0002] Lithium batteries can be charged and discharged repeatedly, and have increasingly become the first choice for power supply of electronic products. However, lithium batteries currently on the market use a positive and negative electrode structure, which has the following defects: [0003] (1) When the capacity of the lithium battery is large and the load is heavy, the heat generated during the charging or discharging process is large, which makes the temperature of the lithium battery rise and affects the use and performance of the battery. [0004] (2) The positive and negative poles of most lithium batteries are arranged in parallel on the same side. This structure has the hidden danger of short circuit between the positive and negative poles during production or use, resulting in battery failure or ev...

Problems solved by technology

[0006] The purpose of the invention of the present invention is to solve the problem that when the existing lithium battery has a large capacity and a heavy load, the heat generated is large, which makes the temperature of the lithium battery rise, which affects the use and performance of the battery. The positive and negative electrodes of the lithium battery are arranged On the same side, this structure has the hidden danger of short circuit between positive and negative poles, causing battery failure or even explosion hazard. The specific solutions are as follows:
