Abstract
The utility model relates to the technical field of the polymer lithium ion secondary battery, in particular to a radiating package for polymer lithium ion secondary battery or polymer lithium ion secondary battery. The utility model is realized through the following technique proposal that the package mainly comprises a battery core and a shell, wherein the battery core is glued inside the shell by insulating and heat conducting adhesive which is filled into the space between the battery core and the shell. The shell is made from unsealed metallic materials and is provided with a plurality of radiation fins on the surface. After the adoption of the structure, firstly, heat produced during the work process of the battery core can be transmitted easily to the surface of the metallic shell and thereby the heat inside the battery or batteries are easier to be radiated; secondly, the battery core is prevented from damage; and lastly, conditions like inflaming and explosion because inside gas can not be discharged out of the sealed shell are not caused, meanwhile the battery or batteries can be prevented from inflaming accidentally by the insulating and heat conducting adhesive which plays the role of inflaming retarding.
Description
Technical field:
The utility model relates to the polymer lithium ion secondary battery technical field, refers in particular to the heat radiation packing of a kind of polymer lithium ion secondary battery or battery pack.
Background technology:
Along with the development of modernized society, mobile device has obtained application more and more widely (as information and the communication industry at high speed development), has formed the wilderness demand to high-energy battery.Exactly for the automobile industry that grows up already, because modernized society is to environmental protection requirement, it is also waiting for safer, the more development of macrocell of capacity.Because the specific energy height of lithium battery and lithium ion battery, thereby obtain the great attention of countries in the world, wherein the liquid electrolyte lithium ion battery has obtained in above-mentioned field to use widely, and the polymer Li-ion battery of colloid (comprising the plasticizing attitude) or solid electrolyte has also begun to obtain to implement.The performance of polymer Li-ion battery is better than liquid state electrolyte battery in many aspects, for example its specific energy density height, manufacture craft is simple, shape is flexible and changeable (can be made into the flat structure of different shape, thickness can less than 1 millimeter), no liquid leakage, long shelf-life, normally do not discharge and recharge and can produce gas or the like.Reveal and normally discharge and recharge Shi Buhui just because of its no liquid and produce gas, so it can adopt the flexible package of light Vacuum Package.But also there is certain deficiency in it, for example work as polymer Li-ion battery and be used for equipment such as similar electric automobile, during as electrokinetic cell, it will reach certain power and energy, usually need the use that is cascaded of many jumbo battery, it also needs bigger operating current simultaneously, thereby inevitably will produce a large amount of heat, the heat radiation of battery or battery pack has also just become an important problem, and the security performance of the direct left and right sides of the quality battery of its radiating efficiency.
The utility model content:
The purpose of this utility model is to provide the heat radiation packing of a kind of polymer lithium ion secondary battery or battery pack.
The utility model is achieved by the following technical solution: the utility model mainly comprises battery and shell, and wherein battery is gluing in shell by insulating heat-conductive, and the space between battery and the shell is filled with insulating heat-conductive glue.
Above-mentioned shell adopts unsealed metal material to make, for example metal such as aluminium, steel.
For increasing radiating efficiency, the surface of above-mentioned shell is provided with some fin.
After adopting this structure, at first, the heat that battery produces when work is easy to conduct to the surface of metal shell, helps distributing of battery or battery pack internal heat; Secondly, because the protection of metal shell is arranged, battery is difficult for impaired; At last, because metal shell adopts non-closed structure, so when battery runs into high temperature and produces gas, the flexible package of its battery that is easy to rise brokenly discharges gas, can not produce because shell is airtight, internal gas can't be discharged and the situation of burning, exploding, and the insulating heat-conductive glue between battery and shell can play fire-retardant effect simultaneously, prevents that battery or battery pack from burning under unexpected situation.

See accompanying drawing 3～6, the utility model comprises: battery 1, shell 2 and insulating heat-conductive glue 3, the some battery 1 that wherein constitute battery or battery pack by insulating heat-conductive glue 3 sticking with shell 2 in, and the space between battery 1 and the shell 2 is filled with insulating heat-conductive glue 3.Accompanying drawing 3～6th, the multiple different embodiment that the utility model can be taked when making, it is not limited in above-mentioned several mode certainly.
Above-mentioned shell 3 adopts unsealed metal material to make, for example metal such as aluminium, steel.
See accompanying drawing 7, in order to increase radiating efficiency, the surface of above-mentioned metal shell 2 is provided with some fin 21, and fin 21 is solidified as a whole with metal shell 2, and fin 21 has increased the area of dissipation of shell 2, improves radiating efficiency.
The utility model has the following advantages after adopting this structure:
At first, the heat that battery produces when work is easy to conduct to the surface of metal shell, helps distributing of battery or battery pack internal heat;
Secondly, because the protection of metal shell is arranged, battery is difficult for impaired;
At last, because metal shell adopts non-closed structure, so when battery runs into high temperature and produces gas, the flexible package of its battery that is easy to rise brokenly discharges gas, can not produce because shell is airtight, internal gas can't be discharged and the situation of burning, exploding, and the insulating heat-conductive glue between battery and shell can play fire-retardant effect simultaneously, prevents the burning of battery or battery pack.
