Abstract
The invention relates to a preparation process of a flame retardant battery, which comprises the step of coating the surface of a battery shell with pulp, with the coating thickness of 5 to 10 microns, wherein the pulp is prepared by the following steps in sequence: (A) weighing following raw materials in mass percent: 50% to 80% of glass fiber, 18% to 43% of solvent and 0.2% to 10% of bonding agent; (B) putting the raw materials weighed in the step (A) into a mixer, and mixing at the rotating speed of 2,000 to 4,000 revolutions, so that the materials are uniformly dispersed, the viscosity is controlled in a range of 1,000 to 4,000, and the solid content is controlled in a range of 40% to 70%; and (C) coating the outer surface of the battery shell with the pulp prepared in the step (B), wherein the coating thickness is 5 to 10 microns. By virtue of a flame retardant material applied to the battery shell, the phenomenon of joint combustion of other batteries caused by combustion of a single battery is effectively prevented, thereby increasing the safety of the battery and avoiding unnecessary loss.
Description
Technical field
The invention belongs to lithium ion battery and manufacture field, be specifically related to a kind of battery flame-proof battery of related combustion case producing that burns under special circumstances that stops.
Background technology
Present lithium from battery in use, when using voltage to exceed battery peace to close voltage 4.2V or inside battery or outside and be short-circuited, can occur to produce heat and be greater than the hot situation of escaping, now can cause the composition in electrolyte decompose and burn, and then fuel cell housing, after battery container burning, can produce related combustion phenomena, because causing the burning of other battery or material, the burning of a battery produces blast.
Summary of the invention
In order to overcome the shortcoming of currently available technology, stop the related combustion reaction producing under special circumstances, the present invention has anti-flaming function material by applying at battery case stops related combustion phenomena, thereby effectively solve its related combustion case, increase greatly the fail safe of battery, avoided unnecessary loss.
For achieving the above object, the present invention by the following technical solutions: a kind of flame-proof battery preparation technology, will adopt the slurry that makes of following sequential steps to be coated in the surface of battery case, coating thickness is 5～10um; The preparation process of described slurry is as follows:
