Problems solved by technology

[0002] The existing battery filler is composed of colloidal materials, and its disadvantages are that it has no heat dissipation function, cannot be flame-retardant, and cannot be explosion-proof. In the case of overcharging the battery, the battery is easy to explode and catch fire, resulting in fire accidents.
At the same time, it is easy to make the lithium battery not moisture-proof and waterproof

Abstract

The invention discloses a new energy lithium battery special packaging material which is prepared from, by weight, 50-60 parts of unsaturated polyester resin, 1-2 parts of bentonite, 5-10 parts of fire retardant, 20-30 parts of heavy calcium powder, 20-30 parts of talcum powder, 3-5 parts of additives and the like. A power lithium battery prepared from the special packaging material has the waterproof, dampproof, fireproof, anti-explosion, fire retardance functions. Meanwhile, the packaging material further has a heat conductive function, heat emitted by the lithium battery in the working process can be dissipated, the service life of the battery is remarkably prolonged, and charging safety of the battery is remarkably improved.

Description

technical field [0001] The invention relates to a battery packaging material, in particular to a special packaging material for a new energy lithium battery. Background technique [0002] The existing battery filler is composed of colloidal materials, and its disadvantages are that it has no heat dissipation function, cannot be flame-retardant, and cannot be explosion-proof. When the battery is overcharged, the battery is easy to explode and catch fire, resulting in fire accidents. At the same time, it is also easy to make the lithium battery not moisture-proof and waterproof. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the purpose of the present invention is to provide a special packaging material for new energy lithium batteries, which can prevent the risk of explosion when the battery is overcharged, and the battery pack using this special packaging material also has waterproof, moisture-proof, and fire-proof properties. ...
