The size of the blanket body 1 is flexible, ranging from 1㎡ to 48㎡, and can be used according to the usage. The blanket body 1 is fixedly connected with a blanket edge 7 on all sides, and the blanket edge 7 is partially in contact with a reinforcement layer 201, a smoke control layer 202, a thermal insulation layer 203, an explosion-proof layer 204, a fireproof layer 205, and a wear-resistant layer 206. A weighted sand 8 is installed on the inner wall of the blanket edge 7 for weighting and pressing the fire control blanket, which is beneficial to reduce the isolation of the fire from the outside air and is beneficial to better assist in extinguishing the burning lithium battery. A protective component 2 is arranged on one side of the blanket body 1, and the protective component 2 includes a reinforcement layer 201, a smoke control layer 202, a thermal insulation layer 203, an explosion-proof layer 204, a fireproof layer 205, and a wear-resistant layer 206 arranged in sequence from the inside to the outside on one side of the blanket body 1;

[0031] The smoke control layer 202 is composed of an activated carbon layer and a zeolite molecular sieve layer. The air permeability of the fire control blanket is not higher than 200 mL / cm-2 / s-1. Good air tightness enables the fire control blanket to effectively isolate the air and prevent the internal combustible gas from penetrating the fire control blanket and overflowing. Combustible gas is one of the necessary elements for combustion. Binding the combustible gas can suppress the intensity of flame combustion and curb the spread of fire.

[0032] The thermal insulation layer 203 is composed of a ceramic fiber layer and a ceramic layer such as a silicon carbide layer. The thermal conductivity of the fire control blanket does not drop higher than 0.15W / m / k. It can withstand fire for more than 60 minutes at a high temperature of 1000°C, and the thermal insulation performance of the material does not significantly decay. With good thermal insulation, the fire control blanket can block heat and effectively prevent the spread of fire, not only preventing the surrounding goods from burning, but also protecting them from heat damage;

The fire control blanket has good explosion resistance and the ability to resist explosion force without breaking, making it easy to deal with the explosion of gas, hydrogen, and lithium batteries.

[0034] The fireproof layer 205 is composed of a silicon nitride layer and a nano-aerogel layer. The fire blanket itself does not burn and produces very little smoke. It can withstand fire for more than 60 minutes at a high temperature of 1000°C, and the fireproof performance of the material does not significantly decay. The heat resistance limit temperature is not less than 1200°C.

[0035] The wear-resistant layer 206 is composed of a carbon fiber layer, a polyphenylene sulfide layer, a ceramic coating, and an intermetallic compound coating, so as to make the fire control blanket more waterproof, moisture-proof, wear-resistant and aging-resistant;

[0036] A connection component 3 is installed on the blanket body 1 and the protection component 2. The connection component 3 includes a plurality of auxiliary holes 301 opened on the blanket body 1 and the reinforcement layer 201, the smoke control layer 202, the thermal insulation layer 203, the explosion-proof layer 204, the fireproof layer 205, and the wear-resistant layer 206.

At the same time, the connecting component 3 set between the blanket body 1 and the protective component 2 can fix the lithium battery fire control blanket.

[0038] like Figure 2 - Figure 4 As shown, the connection component 3 is connected to the storage component 4, and the storage component 4 includes spring buckles 401 arranged on two auxiliary rings 303, and a storage belt 402 is passed through the spring buckle 401 for storing the lithium battery-specific fire control blanket, and a clamping joint 403 is fixedly arranged at one end of the storage belt 402, and a clamping seat 404 is passed through the other end of the storage belt 402, and the inner wall of the clamping seat 404 is clamped with the clamping joint 403, and an adjustment buckle 405 is fixedly installed on one side of the clamping seat 404, and one side of the adjustment buckle 405 is fixedly connected with the clamping seat 404, and the adjustment buckle 405 part is passed through the storage belt 402;
