Embodiment 1

[0042] Example 1 A thermal battery cell testing device

[0043] The device includes a single battery assembly system and a single battery electrical performance testing system, figure 1 Assemble the system for the single cell.

[0044] combine Figure 2-5 , it can be seen that the single battery assembly system includes a first stainless steel bracket 1, a motor 2, an upper pressure plate 3, an upper insulating sheet 4, and an upper current collecting sheet 5. The upper current collecting sheet 5, the upper insulating sheet The sheet 4 and the upper pressure plate 3 are a whole, and the upper pressure plate 3 is connected to the motor 2 through the top opening of the heating furnace 15 and is fixed on the first stainless steel bracket 1;

[0045] It also includes a second stainless steel bracket 6, a material pushing device 7, a single battery 8, an anti-overflow ring 9, a stainless steel sheet 10, a lower collector sheet 11, a lower insulating sheet 12, a lower pressure pla...

Embodiment 2

[0051] Example 2 A thermal battery cell testing device

[0052] In the thermal battery single cell testing device, the anti-overflow ring 9 is a perforated asbestos sheet or a mica sheet, and the bottom is fixed on the stainless steel sheet 10 . During the test, the single battery 8 is assembled into the inner hole of the anti-overflow ring 9 , and then the stainless steel sheet 10 is fixed on the top of the anti-overflow ring 9 .

[0053] In the thermal battery single cell testing device, the inner diameter of the anti-overflow ring 9 is larger than the diameter of the single cell 8, the outer diameter of the anti-overflow ring 9 matches the diameter of the stainless steel sheet 10, and the thickness of the anti-overflow ring 9 It matches the thickness of the unit cell 6 .

[0054] Specifically, the inner diameter of the overflow prevention ring 9 is 35 mm, the outer diameter is 45 mm, and the thickness is 0.8 mm, and the diameter of the stainless steel sheet 10 is 45 mm.

Embodiment 3

[0057] Example 3 Single battery

[0058] The single battery 8 in the present invention is formed by pressing the negative electrode material, the diaphragm material and the positive electrode material under the pressure of 3t-10t, and the negative electrode material is lithium boron alloy, lithium silicon alloy or lithium aluminum alloy; the diaphragm The material is a mixture of ternary all-lithium electrolyte LiF-LiCl-LiBr and MgO, and the cathode material is FeS 2 or CoS 2 , ternary all-lithium electrolyte LiF-LiCl-LiBr and Li 2 A mixture of O. The single cell 8 has a diameter of 32 mm and a thickness of 0.8 mm.

[0059] The preparation of the single cell 8 includes:

[0060] (1) Negative electrode material: the negative electrode material is preferably a lithium boron alloy;

[0061] (2) Diaphragm material: The diaphragm material is a mixture of ternary all-lithium electrolyte LiF-LiCl-LiBr and MgO, which is composed of 5% LiF, 10% LiCl, 35% LiBr and 50% MgO.

Abstract

The invention belongs to the technical field of thermal battery testing, and in particular relates to a thermal battery single cell testing device and a testing method. The device includes a single battery assembly system and a single battery electrical performance testing system. The single battery assembly system includes a first stainless steel bracket, a motor, an upper pressure plate, an upper insulating sheet, an upper current collector sheet, and a second stainless steel bracket , push-back device, single cell, anti-overflow ring, stainless steel sheet, lower collector sheet, lower insulating sheet, lower pressure plate, pressure sensor and heating furnace; no need to repeatedly assemble the single cell assembly system for each test , which greatly simplifies the assembly and testing difficulty of the single battery, and ensures the consistency of the single battery test conditions; the constant temperature system and the constant pressure system are set separately, which will not cause damage to the heating device under high pressure, ensuring two The stability of the respective work of the system.

Description

technical field [0001] The invention belongs to the technical field of thermal battery testing, and in particular relates to a thermal battery single cell testing device and a testing method. Background technique [0002] A thermal battery is a thermally activated primary reserve power source that uses the battery's own heating system to heat and melt a non-conductive solid-state salt electrolyte into an ionic conductor and enter a working state. It is mainly used as the main power source for nuclear weapons such as aviation missiles and torpedoes. The thermal battery is composed of numerous single cells in series and parallel. Each single cell adopts a three-in-one production method, that is, it is composed of a positive electrode, an electrolyte and a negative electrode; 2 and CoS 2 , The negative electrode generally uses lithium-silicon alloy, and lithium-boron alloy can be used under high power and high flow density. The electrolyte adopts two LiCl-KCl electrolyte or te...
