Problems solved by technology

Although scientific and technological workers at home and abroad have done a lot of research on molten salt electrolytes with low melting point and high conductivity, the molten salt systems mainly include eutectic systems such as KCl-LiCl, LiCl-LiBr-KBr, etc., but they are still far from perfect.

Abstract

The invention discloses a method for preparing fused salt electrolyte, belonging to the technical field of the electrolyte material and a preparation method thereof. The aims of reducing the melting point, increasing the conductivity and improving the stability are fulfilled by adjusting the weight percentage of components. The whole experimental process is performed in a dry environment with RH less than and equal to 2 percent. The raw materials in weight percentage are 15 to 20 of LiCl, 15 to 20 of KCl, 30 to 35 of LiBr and 25 to 40 of KBr. The raw materials are dried in vacuum, dehydrated, cooled, weighed according to the weight percentage and ground evenly. The mixed evenly raw materials are heated to increase the temperature slowly in a high temperature furnace so as to melt completely and keep the temperature, the mixture is cooled to the room temperature together with the furnace, and the obtained fused salt is crushed and ground mechanically to obtain the fused salt electrolyte. The prepared fused salt electrolyte has the characteristics of low melting point, high conductivity and good thermal stability.

Description

technical field [0001] The invention belongs to the technical field of electrolyte materials and their preparation, and in particular relates to a method for preparing a molten salt electrolyte. Background technique [0002] The thermal battery is a kind of thermally activated reserve battery that uses the heating system of the battery itself to heat and melt the non-conductive solid-state salt electrolyte into an ionic conductor and enter the working state. Heating reserves and long-term storage are two characteristics of thermal batteries. After activation, it can be charged at 1500mA / cm in a short time 2 Density discharge, can also be low current density (<50mA / cm 2 ) for several hours. Due to its high working temperature (350-550°C), high specific energy, high specific power, high discharge rate, wide operating environment temperature, long storage time (up to 10-25 years), and short activation time (0.2-0.5s) space), compact structure, simple process, low cost an...
