Embodiment 1

[0029] A battery with a fireproof function includes a sealed casing 1 and a battery body 2 arranged in the sealed casing. A fireproof material filling cavity 4 is arranged between the sealed casing 1 and the battery body 2. A fireproof board 3 is fixedly arranged on the inner surface of the sealed casing 1, and the fireproof material filling cavity 4 is arranged between the fireproof board 3 and the battery body 2.

[0030] The fireproof material filling cavity 4 is filled with dry powder fire extinguishing agent. The dry powder fire extinguishing agent is sodium bicarbonate, sodium chloride or potassium chloride dry powder fire extinguishing agent. The sealed enclosure 1 includes a lower shell 11 and an upper shell cover 12 that are sealed but connected. Both the lower shell 11 and the upper shell cover 12 are provided with a fireproof material filling cavity 4, and the upper shell cover 12 is provided with a communication The wire tubes 13 on the upper and lower sides of the c...

Embodiment 2

[0039] A thermally conductive partition plate 5 fixedly connected to the fireproof board 3 is provided between the fireproof filling cavity 4 and the battery body 2, and the thermally conductive partition plate 5 forms a battery inner positioning shell, and the battery body is placed in the battery The surface of the thermally conductive partition plate 5 facing the battery body 2 is attached to the surface of the battery body 2 inside the casing. A metal plate can be used for the thermally conductive separator, which not only ensures the thermal conductivity but also increases the strength of the battery.

[0040] The material of the sealing shell 1 includes a metal layer, a polypropylene plastic layer, and a ceramicized silicone rubber layer in order from the inside to the outside, wherein the ceramicized silicone rubber layer is calculated in parts by weight and is made of the following raw materials: silicon 100 parts of rubber, 80 parts of porcelain filler, 20 parts of flux,...

Embodiment 3

[0047] The difference from the above embodiment is that the dry powder fire extinguishing agent is sodium bicarbonate dry powder fire extinguishing agent, and the battery body 2 is a lithium battery body.

[0048] The material of the sealing shell 1 includes a metal layer, a polypropylene plastic layer, and a ceramicized silicone rubber layer in order from the inside to the outside, wherein the ceramicized silicone rubber layer is calculated in parts by weight and is made of the following raw materials: silicon 100 parts of rubber, 60 parts of porcelain filler, 15 parts of flux, 0.5 part of platinum catalyst, 6 parts of hydroxy silicone oil, 3 parts of vulcanizing agent. Among them, the porcelain filler is a mixture of aluminum silicate fiber and acicular wollastonite. The mass ratio of aluminum silicate fiber and acicular wollastonite is 20:35.

[0049] The metal layer is made of nickel-plated carbon steel.

[0050] The polypropylene plastic layer is made of carbon fiber reinforced...

Abstract

The invention discloses a structure of a fire-proof explosion-proof type new energy vehicle battery, comprising a sealed shell and a battery body arranged in the sealed shell. A fire-proof material filling cavity is arranged between the sealed shell and the battery body, and the fire-proof material filling cavity is filled with a dry powder extinguishing agent. A fire-proof plate is fixed on the inner surface of the sealed shell, and a filling cavity of the fire-proof material is arranged between the fire-proof plate and the battery body. The sealing shell material sequentially comprises a metal layer from the inside to the outside, polypropylene plastic layer, ceramic silicone rubber layer, wherein the ceramicized silicone rubber layer is formed in an amount of parts by weight of the ceramic silicone rubber layer, It is prepared from the following raw materials: 100 parts of silicone rubber, 40-80 parts of porcelain filler, 5-20 parts of flux, 0. 2-1.5 parts of platinum catalyst, 2-8parts of hydroxyl silicone oil and 2-4 part of vulcanizing agent, wherein that porcelain filler is a mixture of aluminum silicate fiber and acicular wollastonite, wherein the mass ratio of aluminum silicate fiber to acicular wollastonite is 15-25:30-40.

Description

Technical field [0001] The invention belongs to the technical field of new energy batteries, and specifically relates to a fire-proof and explosion-proof new energy automobile battery structure. Background technique [0002] Storage Battery is a device that directly converts chemical energy into electrical energy. It is a rechargeable battery designed to recharge through a reversible chemical reaction. It usually refers to a lead-acid battery, which is a type of battery , Belongs to the secondary battery. Its working principle: When charging, use external electric energy to regenerate internal active materials, store electric energy as chemical energy, and convert chemical energy into electric energy again when it needs to be discharged. The shell of the battery is mainly made of plastic material, usually polypropylene, ABS and other plastics. In order to meet the requirements of fire and flame retardancy, flame retardants are added to the matrix. Most of them are halogen-contai...
