Embodiment Construction

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0024] First of all, the current mainstream research direction of high-temperature lithium batteries is to find new electrolytes, such as molten salt electrolytes that can be liquid at lower temperatures, and to find molten salt electrolytes with higher conductivity. However, changing the shape of the shell of the high-temperature lithium battery has been neglected, and the performance of the high-temperature lithium battery can also be improved by changing the shape of the battery shell of the high-temperature lithium battery.

[0025] Secondly, by changing the shape of the high-temperature lithium battery, the performance of the high-temperature lithium battery can be improved to a certain extent in a relatively quick way, so that it can wor...

Abstract

The invention aims at providing a method for testing the influence of the appearance of a lithium battery on the heat conduction of the lithium battery. The method comprises the following steps: filling aluminium hydroxide powder, as an inner core of a simulating battery, with same mass into four column-body containers; putting dry yellow sand into a stainless-steel round box body, carrying out heating, and overturning continuously in heating to enable the temperature at the upper part and the temperature at the lower part to be relatively uniform; when the temperature of the surface of the yellow sand reaches 120 DEG C, carrying out insulation by using a relatively small flame so as to enable the temperature of the surface of the yellow sand to be constant; burying the containers into the yellow sand, enabling the yellow sand and the aluminium hydroxide powder in the containers to be on same planes, and inserting a DIS temperature sensor into the center of the powder in each container. Compared with the existing product, the method provided by the invention has the advantages that the performance of the high-temperature lithium battery can be improved to a certain extent in a relatively fast mode, the practical effect is achieved and the purposes are achieved.

Description

technical field [0001] The invention relates to the field of power supplies, in particular to a method for testing the influence of the shape of a lithium battery on the heat conduction of the lithium battery. Background technique [0002] People's daily life is inseparable from electric energy. The so-called power source (source of electric energy) refers to the direct conversion of certain energy (such as chemical energy, light energy) into Electrical energy device. [0003] A device that directly converts chemical energy into electrical energy by chemical changes is called a chemical power source (for example, dry cell, storage battery, etc.). Devices that directly convert light energy and heat energy into electrical energy through physical changes are called physical power sources (for example, solar cells, isotope thermoelectric cells, etc.). [0004] Chemical power sources are traditionally referred to as batteries. During the working process of batteries, two necess...
