Embodiment 1

[0032] (1) Single battery preparation

[0033] The single battery 5 includes a graphite substrate, negative electrode material, diaphragm material, and positive electrode material.

[0034] 1) negative electrode material: the negative electrode material is LiB alloy;

[0035] 2) Preparation of diaphragm material: Take ternary all-lithium electrolyte LiF-LiCl-LiBr and MgO, according to mass ratio, ternary all-lithium electrolyte LiF-LiCl-LiBr:MgO=1:1, mix well. The ternary all-lithium electrolyte LiF-LiCl-LiBr is composed of 9.6% anhydrous LiF, 22% anhydrous LiCl and 68.4% LiBr by weight percentage.

[0036] 3) Preparation of cathode material:

[0037] a) Vacuum drying: take NiS respectively 2 , FeS 2 , Li 2 O and the binary electrolyte LiCl-KCl are placed in a vacuum drying oven for drying, the drying temperature is 120±10°C, the relative vacuum degree is ≤-0.09Mpa, and the drying time is 8 hours. The binary electrolyte LiCl-KCl is composed of 45 wt% anhydrous LiCl and 5...

Abstract

The invention belongs to the technical field of thermal batteries, and relates to a battery cell testing device and method for a thermal battery. The device comprises a gas path system, a temperaturecontrol system, a battery cell assembly system and a battery cell testing system; and the battery cell assembly system comprises a base 1, an insulating sheet 2, a negative electrode current collectorplate 3 connected with a negative electrode current and voltage collecting line, a fixed mould 4, a battery cell 5, a positive electrode current collector plate 6 connected with a positive electrodecurrent and voltage collecting line, an insulating sheet 7, a pressure head 8, a top plate 9, a fastening screw 10 and a pressure head fastening screw 11. The battery cell testing is performed by using the battery cell testing device for the thermal battery, so that the time can be saved, and the research and development cost can be reduced; the contradiction between the yield of a novel materialin a research and development process and the amount of powder needed in a traditional thermal battery testing process is relieved; and the serialized research of thermal batteries of different systems can be carried out conveniently.

Description

technical field [0001] The invention relates to the technical field of thermal batteries, in particular to a thermal battery single cell testing device and a single battery testing method. technical background [0002] Thermal battery is an important military reserve power source, and its development level directly affects the national defense and military level.
