How Thermal Battery Work
A thermal battery is a thermally activated primary reserve battery. Generally, the electric stack composed of several single cells connected in series and in parallel together with the heating sheet is put into the combination case, and the electric stack is connected to the terminal on the battery cover through the drain strip, and the whole battery is composed of electric stack, activation mechanism, combination The shell and combined cover are welded by argon arc welding.
A single battery is composed of a positive electrode, an electrolyte, and a negative electrode. Both ends of each single battery are equipped with heating sheets. When the battery is required to work, use an external electrical signal or mechanical force to ignite the igniter inside the battery, ignite the heating system inside the battery, and make the single battery reach its working temperature (400-600°C), and the non-conductive under normal temperature The solid electrolyte is heated and melted to form an ionic conductor, and an electrochemical reaction occurs between the positive and negative electrodes to generate electric energy. After being connected to the external circuit, the battery enters the working state.
