Detailed description of the invention
With reference to Fig. 1-Fig. 4, the safe soft package lithium battery of one of the present utility model, including battery core 1, fire extinguishing layer 2, sealant 3, heat dissipating layer 4, aluminum plastic film 5 and safety tab 6.
Fire extinguishing layer 2 includes low melting point polymer fire extinguishing outer layer, is filled with efficient flame-retarding agent extinguishing chemical in fire extinguishing layer 2.Fire extinguishing layer 2 is positioned at battery core 1 four limit, and fire extinguishing layer 2 thickness is with battery core 1 thickness.Wherein, fire prevention shell is that fusing point is less than 190 DEG C of insulation high polymer materials, and extinguishing chemical is carbon tetrachloride.When the internal battery core 1 catching fire explosion time of Soft Roll lithium rechargeable battery aluminum plastic film, when internal temperature of battery is higher than 190 DEG C, battery core 1 four frontier defense fire bed 2 outer layer melts the most immediately and ruptures, in fireprotection layer, carbon tetrachloride extinguishing chemical covers on battery core 1 surface, stops or reduces battery core 1 catching fire explosion safety accident.
Sealant 3 cladding is sealed in aluminum plastic film Soft Roll lithium rechargeable battery four limit, and sealant 3 includes that 4 battery fixing holes 31, sealant 3 material are insulating heat-conductive waterproof polymer.Sealant 3 is possible to prevent aluminum plastic film soft-package battery R Jiao Chu and four limits to rupture leakage.Further increase battery security.
Heat dissipating layer 4 is positioned at the upper and lower surface of aluminum plastic film Soft Roll lithium rechargeable battery, and described heat dissipating layer 4 is radiating fin, and described sealant 3 and heat dissipating layer 4 use Shooting Technique integral sealing to fix.Finstock material is rustless steel, can be effectively improved battery radiating efficiency.
Safety tab 6 includes lug back segment, lug stage casing and lug leading portion, this lug back segment welds with battery core 1 pole piece in aluminum plastic film Soft Roll lithium rechargeable battery inside, lug stage casing is stretched out outside aluminum plastic film Soft Roll lithium rechargeable battery, lug stage casing includes overcurrent fuse wire part 61, overcurrent fuse wire part 61 is bismuth that fusing point is 138 DEG C, antimony, the alloy that the trace element such as stannum are made, when temperature is more than 138 DEG C, overcurrent fuse wire part 61 fuses in time, power supply is played open circuit effect, avoid power supply, due to short circuit and the big electric current of over loading, explosion safety accident on fire occurs, protect power supply in time, electrical appliance and operator's personal safety.Transparent insulation heat conduction fish tail and waterproof layer 62 it is coated with outside lug stage casing; protective layer 62 is for being coated on lug stage casing exterior clear ambroin; the material of wherein said transparent insulating plastic is Merlon, polyethylene, polypropylene or silica gel; described lug leading portion is provided with fixing nut 63, and safety tab 6 corner is circular arc.The fixing bolt that lug in safety tab 6 is fixed on nut 63 is taken off, can be with changing soft package lithium battery, safety is easy.
