Abstract
Description
Technical Field
[0001] This utility model relates to the field of sodium-ion battery technology, and in particular to a sodium-ion battery that is leak-proof and breakable. Background Technology
[0002] The purpose of leak-proof and breakable sodium-ion batteries is to prevent internal electrolyte leakage and external moisture intrusion, while also having a certain degree of resistance to physical impact to ensure safe use even if damaged or broken. This type of battery uses special sealing materials and technologies to enhance its leak-proof performance.
[0003] Common sodium-ion batteries may experience a rapid rise in internal temperature when overcharged, short-circuited, or physically damaged, leading to thermal runaway. Once thermal runaway occurs, the internal chemical reaction accelerates, generating a large amount of heat and gas, further exacerbating the temperature rise and creating a vicious cycle. Due to the lack of effective self-extinguishing function, once a battery cell catches fire, the flames and high temperature can easily spread to adjacent cells, causing greater damage.
[0004] Therefore, regarding the aforementioned sodium-ion batteries, due to the lack of effective self-extinguishing function, flames and high temperatures can easily spread to adjacent units, causing greater damage. A leak-proof and breakable sodium-ion battery could be designed. Upon detecting abnormal temperature rise or other fire signals, an emergency response would be immediately triggered. An electric push rod would push a latch to quickly open the enclosure door, releasing a dry powder extinguishing agent in one go. This agent would evenly cover the battery surface, rapidly suppressing the spread of flames and preventing thermal runaway. After the flames are extinguished, a vacuum pump would be activated to extract air from the enclosure, reducing oxygen content and preventing reignition, thus solving the aforementioned problems. Utility Model Content

[0007] Preferably, upon detection of abnormal temperature rise or other fire precursor signals, the emergency response procedure is immediately triggered.

The dry powder extinguishing agent is released all at once from the storage tank, evenly covering the battery surface, quickly suppressing the spread of flames, preventing thermal runaway, and ensuring fire extinguishing efficiency. After the flames are extinguished, the vacuum pump is activated to extract air from the cabinet, reducing the oxygen content and preventing reignition. At the same time, harmful gases generated are discharged through the exhaust pipe, reducing the impact on the surrounding environment.

[0026] During operation, if abnormal temperature rise or other fire precursor signals are detected, the emergency response procedure is immediately triggered. Upon receiving the instruction, the electric push rod 7 pushes the latch 8, quickly opening the cabinet door 5. The dry powder extinguishing agent storage tank 4 releases the dry powder extinguishing agent, which is then released all at once, evenly covering the battery surface to quickly suppress the spread of flames, prevent thermal runaway, and ensure extinguishing efficiency. After the flames are extinguished, the vacuum pump 19 is activated to extract air from the cabinet, reducing the oxygen content and preventing reignition. Simultaneously, harmful gases generated are discharged through the exhaust pipe 20 to reduce the impact on the surrounding environment. The information storage module 13 records temperature changes inside the cabinet.

[0027] Through the above steps, if abnormal temperature rise or other fire precursor signals are detected, the emergency response procedure is immediately triggered. Upon receiving the instruction, the electric push rod 7 pushes the latch 8, quickly opening the cabinet door 5. The dry powder extinguishing agent storage box 4 releases the dry powder extinguishing agent. The dry powder extinguishing agent is released all at once from the dry powder extinguishing agent storage box 4, evenly covering the battery surface, quickly suppressing the spread of flames, preventing thermal runaway, and ensuring fire extinguishing efficiency. After the flames are extinguished, the vacuum pump 19 is activated to extract air from the cabinet, reducing the oxygen content and preventing reignition. At the same time, the harmful gases produced are discharged through the exhaust pipe 20, reducing the impact on the surrounding environment. This addresses the common problem of sodium-ion batteries, which, due to the lack of effective self-extinguishing functions, allow flames and high temperatures to easily spread to adjacent units, causing greater damage.
