Description

Technical Field

[0001] The present invention relates to the technical field of lithium batteries, and particularly to an explosion-proof solid-state lithium battery. Background Art

[0002] A solid-state lithium battery is a new type of lithium-ion battery technology that uses a solid electrolyte instead of a traditional liquid or gel electrolyte. The charge and discharge process is achieved by the movement of lithium ions between the positive and negative electrodes, and it is usually used in fields such as electric vehicles, renewable energy storage systems, and portable electronic devices.

[0003] When assembling lithium batteries, workers need to arrange individual lithium batteries one by one between the partitions of the lithium battery frame according to the design drawings, use a fixing device to limit and fix the individual lithium batteries, use wires to connect the individual lithium batteries in series or parallel, and then place a cover plate on the top of the lithium battery frame and use bolts to limit and fix the lithium battery frame and the cover plate.

[0004] Since the sizes of individual lithium batteries in different application scenarios are different and the distance between the partitions cannot be adjusted, the distance between the individual lithium batteries and the partitions is relatively close. When an individual lithium battery catches fire, the extreme temperature and pressure generated will penetrate the partition and affect the adjacent individual lithium batteries, resulting in a chain explosion.

Place a single lithium battery between the limit plates 38, rotate the limit knob 39 to drive the limit block 37 to move through the bidirectional threaded rod 36. The limit block 37 drives the limit plate 38 to move to limit and fix the single lithium battery. After the single lithium battery is limited and fixed, close the door panel 26 and use the buckle 29 to limit and fix it. Start the cooling circulating water device 32 to inject cooling water into the cooling water plate 34 through the connecting water pipe 33 to dissipate heat from the single lithium battery. When the single lithium battery catches fire, the temperature sensing device 30 senses the temperature of the single lithium battery and starts the corresponding air pump 21 through the control device 31 to inject carbon dioxide from the carbon dioxide tank 20 into the connecting plate 23 through the manifold 22. The carbon dioxide is injected into the lithium battery frame 1 from the first one-way plate 28 through the first groove 24. The carbon dioxide sinks and the oxygen rises. The oxygen is discharged from the second one-way plate 28 through the second groove 27. The carbon dioxide covers the single lithium battery to cut off oxygen and extinguish the fire.
