The thermal battery is a primary reserve battery activated by melting molten salt as an electrolyte by using a self-contained heat source. The method has the advantages of short activation time, wide use environment temperature, long storage period and no maintenance, and is more and more widely applied to weapon equipment systems.
The diaphragm material used by the thermal battery is formed by mixing an electrolyte (E) and a binder (B) according to a certain proportion and then fusing at high temperature. The electrolyte is commonly LiCl-KCl, LiCl-LiBr-LiF-KBr and other eutectic salts, the electric conductivity of the halogen salt is very high when the halogen salt is molten, but the electric conductivity is very low at normal temperature, and the electrolyte is particularly suitable for the requirements of high-power discharge and long-time storage of a thermal battery; the binder is used for inhibiting electrolyte flow, and is typically MgO or SiO2、Al2O3The oxides have strong adsorption force, keep the electrolyte from melting and leaking when the thermal battery works, and resist the leakageThe temperature is higher, can satisfy the temperature requirement of thermal battery during operation.
At present, the diaphragm material for the thermal battery is prepared by manual operation, and the process is relatively complicated. For example, the literature "terrestris, liuxiajiang, thermal battery, beijing: the national defense industry press, 2005, "pp 241-243, indicates a method for preparing a separator material (also called electrolyte EB):
(1) placing MgO in a crucible, putting the crucible into a muffle furnace, and heating and burning.
(2) According to the total amount of the materials of the Electrolyte (EB) to be prepared, the electrolyte (E) and MgO are respectively weighed and put into a ball milling tank, and a proper amount of corundum balls are added and are ball milled and mixed on a ball mill.
(3) And (3) placing the uniformly mixed mixture into a crucible, putting the crucible into a muffle furnace, and heating and melting the mixture.
(4) Transferring the melted mixture into a ball milling tank, adding a proper amount of corundum balls, placing the mixture on a ball mill for ball milling, and sieving the mixture through a 100-mesh sieve after ball milling. Bottling, sealing, and storing in a desiccator.
The process method is suitable for small-batch manual operation, and the materials are transferred by manual handling. The melting and ball milling process is time-consuming and energy-consuming, the melting time of each batch needs 10 hours, and the ball milling time needs 2-3 hours. By adopting the method, the preparation efficiency of the diaphragm material is (18-25) h/kg, the preparation energy consumption of the diaphragm material is (80-100) kW/kg, the efficiency is low, and the energy consumption is high. In addition, in the ball milling process, the corundum balls can tamp MgO powder on the wall of the ball milling tank, so that the wall adhesion problem is caused, and the mixing uniformity of the binder and the electrolyte is influenced.
In CN105703002A electrolyte material for thermal battery and its preparation method2O3The safety problem of the thermal battery is expected to be solved for the adhesive, but the preparation method of the thermal battery is basically consistent with the method for preparing the diaphragm material proposed by the Lurui and the like, the diaphragm material is prepared by mixing the electrolyte and the adhesive, fusing and sintering and ball milling after fusing, and the problems of low efficiency, high energy consumption and uneven mixing during the preparation of the diaphragm material cannot be solved.
