[0026] Example 1
[0027] The unit thermobattery stack structure is 2 sets of parallel outputs, with 2 positive lead wires and 1 negative lead wire. The stack height is 100mm, and the stack diameter is 66mm as an example. The short mica strip size is 20mm×20mm×0.1mm. , Long mica strip size is 20mm×100mm×0.1mm, soft mica plate 230mm×100mm×0.2mm, glass cloth tape size is 1500mm×15mm×0.1mm (excess size can be cut off after winding). The insulation protection assembly method of the positive and negative lead wires is as described above, and then the battery is subjected to a structural test according to the random vibration spectrum of a thermal battery (total root mean square Grms=32g, vibration time per axial 100min), and then centrifuged at 27g During discharge, the voltage curve is stable and the battery is safe and reliable. After the battery is dissected, the lead-out wire of the stack is protected intact and the insulating protective layer is firmly fixed.
