Abstract
The invention provides a battery thermal runaway flue gas treatment device and a battery, and mainly solves the problems that the existing battery thermal runaway flue gas treatment mode is not thorough in treatment, and the treatment device is large in size and complex in structure. The battery thermal runaway flue gas treatment device comprises a reaction unit and an adsorption unit which are connected; the reaction unit comprises N reaction devices connected in series, reaction substances are arranged in the reaction devices, and the reaction substances can chemically react with combustible gas and/or acid gas to convert the combustible gas and the acid gas into non-combustible gas and non-combustible substances; the adsorption unit comprises M adsorption devices connected in series, and cooling materials and/or adsorption materials are filled in the adsorption devices and used for cooling and/or adsorbing the reacted flue gas. The device is more thorough to the processing of battery thermal runaway flue gas, ensures that the gas after handling can not burn for battery security promotes by a wide margin.
Description
Technical Field
The invention belongs to the field of batteries, and particularly relates to a battery thermal runaway flue gas treatment device and a battery.
Background
The application field of the lithium ion battery is very wide, and in recent years, with the further development of the energy storage field of the lithium ion battery, the safe use of the lithium ion battery is also concerned. Because lithium ion battery's principle and structural feature, often generate heat because of the internal resistance in the use repeatedly and produce great heat, the heat can increase gradually moreover, if accumulational heat does not effectively distribute, the temperature then can further rise, when the temperature reaches the limit, the thermal balance of battery then can be destroyed, arouse a series of self-heating side reaction, produce a large amount of combustible gas, the phenomenon of "thermal runaway" appears, can lead to finally that the battery is inside to catch fire, arouse the explosion when serious, cause the hidden danger to user's personal safety.
The Chinese patent application CN108417757A provides a safe lithium battery and a preparation method thereof, the lithium battery in the scheme comprises an electric core and a safe explosion-proof device, the safe explosion-proof device is a material bag, a gas adsorption body is arranged in the material bag, the gas adsorption body is activated carbon, a molecular sieve or a mixture of the activated carbon and the molecular sieve, and the high-temperature substances sprayed out of the battery are directly adsorbed in the scheme. However, when the adsorbent used is used for adsorption, such as activated carbon and molecular sieve, the adsorption effect is worse as the temperature of the adsorbed substance is higher, for example, the adsorption temperature of the activated carbon to gas substances is below 50 ℃, and the temperature of the gas sprayed during thermal runaway of the battery is generally higher than 300 ℃, and at this temperature, the activated carbon loses the adsorption function to the gas substances and has the desorption function to the adsorbed substances, and although the adsorbent can absorb gasified electrolyte at this temperature, the adsorbent cannot adsorb combustible gas substances such as hydrogen, carbon monoxide and methane generated during thermal runaway of the battery, and these substances still have the danger of explosion during thermal runaway of the battery.
Chinese patent application CN112870969A discloses a thermal runaway flue gas catalytic purification system for a power lithium battery pack, which comprises a housing, wherein a battery pack is installed in the housing; a smoke sensor is arranged on the lower surface of the top of the shell; the shell and the top of the shell are both provided with interlayers which are communicated with each other, and air purification materials are arranged in the interlayers. The system adopts the adsorbent and the catalyst to treat smoke generated by battery combustion, and the smoke which is treated by adsorption and catalytic conversion is converted into purified gas to be discharged into air, so that the risk of poisoning of aircrew and passengers due to the inhalation of toxic gas is reduced, and the risk of combustion explosion caused by overhigh temperature and overlarge smoke concentration is reduced.
Disclosure of Invention
