Abstract

The invention relates to the technical filed of thermal batteries, and discloses a thermal battery thermal protection device and a thermal battery. The device comprises an upper supporting plate, a lower supporting plate, a connecting piece for connecting the upper supporting plate and the lower supporting plate, a partition plate which is arranged between the upper supporting plate and the lowersupporting plate and is connected with the connecting piece, and a first thermal insulation component and a second thermal insulation component which are arranged on the upper and lower surfaces of the partition plate respectively, wherein the partition plate is used for partitioning a galvanic pile of the thermal battery into equal galvanic pile units, and the equal galvanic pile units are in contact with the first thermal insulation component and / or the second thermal insulation component. Therefore, the heat accumulated at the middle part of the galvanic pile is dispersed effectively, the influence of the heat on the safety of the battery is reduced, and the output reliability of the battery is improved.

Description

technical field [0001] The invention relates to the technical field of thermal batteries, in particular to a thermal protection device for thermal batteries and a thermal battery. Background technique [0002] The unit thermal battery (single battery) is composed of a battery stack, a battery cover assembly, a battery shell assembly, etc., and the electrical performance output is realized through the battery cover pole. At present, with the development and progress of the thermal battery technology, the volume of the thermal battery is getting larger and higher, and the height of the thermal battery is getting higher and higher, and the core working part of the thermal battery is also getting higher and higher. Since the thermal battery works by heat, a higher stack will inevitably accumulate more heat. According to the conventional stack structure design, the heat generated by the stack will not be effectively controlled, which will affect the safety and electrical performa...
