Abstract

The invention discloses a heating positive electrode integrated material for a thermal battery and a preparation method of the heating positive electrode integrated material in the technical field ofthermal batteries. The heating positive electrode integrated material comprises the following components: oxide, metal powder, electrolyte and lithium oxide. The preparation method comprises the following steps: carrying out inert drying on all the components, weighing the components according to the amount, uniformly mixing the oxide, the electrolyte and the lithium oxide, performing transferringinto an inert drying oven or a vacuum drying oven at the temperature of 350-500 DEG C, lithiating for 2-48 hours, performing cooling and crushing, adding the metal powder, and uniformly performing mixing. Compared with a conventional heating material, the heating positive electrode integrated material has the advantages of high heat value, high combustion rate, gentle heat release, small thermalshock to a thermal battery electrode material, reduction of the decomposition of the electrode material, reduction of the weight of a single battery, and improvement of the high specific characteristic of the thermal battery; in the preparation process of the single battery, the heating sheet and the positive electrode sheet are separately pressed, and after the heating and positive electrode integrated material is adopted, the pressing process of the heating sheet can be reduced, the preparation efficiency of the thermal battery is improved, and the labor cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of thermal batteries, and in particular relates to a heating cathode integrated material for thermal batteries and a preparation method thereof. Background technique [0002] Thermal battery is a heat-activated reserve battery that relies on its own heating system to heat and melt the non-conductive solid-state salt electrolyte into an ionic conductor and enter the working state. Thermal batteries have the characteristics of activation at any angle, fast activation speed, long storage time, and strong ability to withstand environmental mechanical conditions. They have been widely used in weapons and equipment. In addition, thermal batteries have also received attention in civilian applications. Research reports on emergency power supply, fire alarm power supply, and underground high-temperature prospecting power supply. [0003] With the continuous development and updating of thermal battery technology, the...
