Description

technical field [0001] The invention relates to the technical field of lithium batteries, in particular to a solid-state lithium battery with a high-temperature explosion-proof protection structure and a manufacturing method thereof. Background technique [0002] Solid-state battery is a kind of battery technology. Unlike lithium-ion batteries and lithium-ion polymer batteries commonly used today, solid-state batteries are batteries that use solid electrodes and solid electrolytes, but use solid-state lithium batteries in high-temperature environments. Due to the high external temperature, it is not conducive to the heat dissipation of the solid-state lithium battery, and it is easy to damage the solid-state lithium battery, which reduces the service life of the solid-state lithium battery. At the same time, in the process of fixing the lithium battery, it is fixed by bolts. It is easy to cause damage to the bolts, which is not conducive to the disassembly and assembly of th...

[0002] Solid-state battery is a kind of battery technology. Unlike lithium-ion batteries and lithium-ion polymer batteries commonly used today, solid-state batteries are batteries that use solid electrodes and solid electrolytes, but use solid-state lithium batteries in high-temperature environments. Due to the high external temperature, it is not conducive to the heat dissipation of the solid-state lithium battery, and it is easy to damage the solid-state lithium battery, which reduces the service life of the solid-state lithium battery. At the same time, in the process of fixing the lithium battery, it is fixed by bolts. It is easy to cause damage to the bolts, which is not conducive to the disassembly and assembly of the battery. At the same time, the solid-state battery is prone to bulging under long-term use, which is not conducive to pressure relief, resulting in the risk of explosion. Therefore, a high-temperature explosion-proof protection is designed. The solid-state lithium battery of structure and its manufacture method are very necessary
