Problems solved by technology

[0003] 1. Most of the existing test devices are built and assembled with organic materials. During the battery test process, the organic materials are easily attacked by the electrolyte and corroded, thus destroying the device, which makes the device components need to be replaced frequently or the device is directly scrapped.
More importantly, the gas produced by the corrosion of organic materials also has a negative impact on battery performance, affecting the accuracy of the test;
[0004] 2. Existing testing devices can generally only test one battery, and cannot conduct parallel experiments on multiple batteries (samples), thus delaying the research and development progress;
[0006] 4. Existing test devices cannot realize variable temperature tests, especially high temperature tests (existing test devices are mostly assembled and constructed of organic materials, which are not resistant to high and low temperatures)
[0007] 5. The air pressure in the test device cannot be accurately monitored
[0012] So far, there is no test device that can be used to test metal ion batteries using solid electrolytes at the same time, and can control the pressure applied to the battery steplessly, and can realize high temperature testing of the battery, and at the same time can realize multiple batteries to test

Embodiment 1

[0069] First assemble the lithium-oxygen button cell in the glove box. Specifically: a commercial Li sheet (diameter 16mm, thickness 1mm) is used as the negative electrode, Super P (SP) carbon material is used as the conductive agent, La0.85Ca0.15Cr0.85O3@Ru (LCC@R) is used as the positive electrode catalyst, Whatman GF / D Glass fiber as diaphragm, CF 3 SO 3 Li / TEGDME is the electrolyte to assemble the battery. Among them, Super P, La 0.85 Ca 0.15 Cr 0.85 o 3 @Ru and the binder PVDF are coated on the nickel foam according to the ratio of 6:3:1 to prepare the positive electrode sheet. The assembled lithium-oxygen battery is tested with a battery testing device 1, Figure 4 The lithium-oxygen battery measured for an embodiment of the present invention is at room temperature charge and discharge electrochemical performance diagram, SP+La 0.85 Ca 0.15 Cr 0.85 o 3 The discharge platform of a lithium-oxygen battery with @Ru as the positive electrode is around 2.6V, and th...

Description

technical field [0001] The invention relates to the field of batteries, in particular to a battery testing device and a using method thereof. Background technique [0002] A metal fuel cell is a rechargeable energy storage battery that uses metal (alkali metal or alkaline earth metal) as fuel and gas (oxygen, carbon dioxide, etc.) as oxidant. Metal fuel cells have the advantages of high power generation efficiency and high energy density, and are considered to be one of the most promising battery technologies in the next generation of energy storage batteries. During the discharge process of metal fuel cells, metals react with oxidizing gases to form solid products; during charging, the solid products decompose to release metals and oxidizing gases. The research on metal fuel cells is still in its infancy. To develop metal fuel cells, it is first necessary to establish a reliable battery test platform and design a stable battery test device. In order to avoid the impact of...
