Description

A conventional thermal battery is a thermally activated and activated pre-storage battery. When stored, the electrolyte is a non-conductive solid. When used, the active chain and the hot sheet are ignited by a power source or an impact to melt the electrolyte into a conductive ion conductor. Activated, the battery operating temperature is 400-600 ° C, the thermal battery activation chain is composed of the excitation element and the ignition element, the electrolyte is usually a mixture of potassium chloride-lithium chloride eutectic salt or lithium halide, the anode activity The material is mostly lithium-based metal alloy, and the positive electrode active material is used as an electrochemical system for metal sulfide or oxide mainly composed of vanadium, iron, cobalt and nickel. The hot plate is a heat source inside the heat battery, and is mixed with iron powder and potassium perchlorate. However, it has the characteristics of high output, and the thermal battery is mostly used as a power source for missiles. For the purpose of life limit of 30 years or more, high pressure due to thermal decomposition during operation, high environmental stress resistance, etc. Sealed by a metal container, the metal terminal on the end cap of the thermal battery is made by a glass sealing technique, and is mainly used as a path for external power supply and power output during operation when the thermal battery is activated. This is the configuration in which the power source is thermally activated.

The conventional heat battery is ignited by the wire-bridge heating method as the starting component of the fire-extinguishing element. This method is susceptible to electromagnetic waves and causes malfunction, resulting in failure; in order to overcome the problem of electromagnetic interference The initial excitation element with high excitation current is easy to cause overload of the system.
