Abstract

The invention discloses a thin thermal battery independent of an electrode system and a heating system, The heating system is wrapped by a heat conductive insulating layer, and the heating system supplies heat to the electrode system from all sides; the preparation method of the electrode system is a pressing method or a thermal spraying method; the active material of the positive electrode material is an alloy compound and a pure substance; and the heat conductive insulating layer has a heat conductivity of 3- 400W / (m.K), the resistivity is more than 1015 [omega] . cm, For materials with melting point above 1200deg c, while ensuring the normal operation of the battery, does not prolong battery activation, and an alloy compound with higher specific energy is used as the active material ofthe positive electrode material, the thickness of the positive electrode sheet is reduced under the same tablet density, and the height of the thermal battery is further reduced. The invention also solves the problem of high voltage safety caused by the series connection of a plurality of single cells.

Description

technical field [0001] The invention relates to the field of thermal batteries, in particular to a thin thermal battery with an electrode system and a heating system independent. Background technique [0002] In the 1960s, the United States Unidynamics and Sandia National Laboratories worked together to develop sheet-type thermal battery technology, which obtained thermal battery pole pieces by cold pressing powder. Sheet technology is also applied in the heating source of thermal batteries, and a new sheet heating source based on iron and potassium perchlorate has been developed. This material retains its size after ignition, produces less gas, and is safer than zirconium / barium chromate thermal paper. In addition, it is easy to control the heat output by adjusting the ratio of iron to potassium perchlorate, and because there is too much iron powder in the heating sheet, the heating sheet also acts as an electronic conductor. The full-chip thermal battery developed by San...
