Abstract

The invention discloses a solid-state lithium battery loss detection method, relates to the technical field of lithium battery loss detection, and solves the technical problem that the use potential safety hazard of a lithium battery is increased due to the fact that the appearance of the lithium battery cannot be monitored in the prior art. The method comprises the following steps of: analyzing appearance information of the lithium battery by an appearance monitoring unit, acquiring the number of areas with abrasion on the surface of the lithium battery, the number of areas with deformation on the surface of the lithium battery and the number of areas with stains on the surface of the lithium battery, acquiring an appearance monitoring coefficient Xi of the lithium battery through a formula, and if the appearance monitoring coefficient Xi of the lithium battery is smaller than an appearance monitoring coefficient threshold value of the lithium battery, judging that the appearance monitoring of the lithium battery is normal; and if the appearance monitoring coefficient Xi of the lithium battery is larger than or equal to the appearance monitoring coefficient threshold value of the lithium battery, judging that the appearance monitoring of the lithium battery is abnormal, and monitoring the appearance of the lithium battery, thereby preventing the situation that the appearance of the lithium battery changes, and consequently the use quality of a user is reduced and potential safety hazards are increased.

Description

technical field [0001] The invention relates to the technical field of lithium battery loss detection, in particular to a detection method for solid state lithium battery loss. Background technique [0002] Solid-state lithium batteries use solid electrolytes such as solid polymers, inorganic lithium-ion conductors or single-ion conductors, and lithium metal as the anode, and these batteries exhibit higher energy densities than lithium-ion batteries using liquid electrolytes. In addition, the solid-state electrolyte is non-flammable and prevents the dendrite growth of lithium metal, thereby providing greatly improved safety; power lithium batteries have the advantages of environmental protection, long cycle life, high storage capacity, and small volume and weight. As one of the important emerging energy sources, it has been widely used in industrial production. During the cyclic operation of the battery pack, conditions such as high cell temperature, excessive current, over...
