Description
Technical field
This utility model relates to lithium-ion-power cell group field, in particular to a kind of lithium-ion electric core combo mould
Block.
Background technology
Lithium-ion electric core is a kind of secondary cell (rechargeable battery), and it relies primarily on lithium ion and moves between a positive electrode and a negative electrode
Move work.In charge and discharge process, Li+ between two electrodes come and go embed and deintercalation: during charging, Li+ from positive pole deintercalation,
Embedding negative pole through electrolyte, negative pole is in rich lithium state；During electric discharge the most contrary.Battery core typically uses the material containing elemental lithium
As electrode, it it is the representative of modern high performance battery.Lithium system battery core is divided into lithium cell and lithium-ion electric core.Mobile phone and notebook electricity
What brain used is all lithium-ion electric core, and usual people's custom is called lithium battery, and real lithium battery is big due to danger, seldom
It is applied to day electronic product.Lithium-ion electric core has the advantages such as lightweight, capacity big, memory-less effect, thus has obtained general
Power supply is made, although its price is the most high comparatively speaking all over applying present many digital equipments all to have employed lithium-ion electric core
Expensive.The energy density of lithium-ion electric core is the highest, and its capacity is 1.5～2 times of the ni-mh battery core of same weight, and has the lowest
Self-discharge rate.Additionally, lithium-ion electric core is also that it is extensive almost without " memory effect " and without the advantage such as noxious substance
The major reason of application.
Lithium-ion-power cell group refers to the lithium-ion electric driven by electric discharge to equipment, apparatus, model, vehicle etc.
Pond group.Lithium-ion-power cell component high power capacity and high power two types.High-capacity lithium ion power battery group can be used for electricity
Power driven tools, bicycle, scooter, mine lamp, medical apparatus and instruments etc.；High power lithium ion power battery group is mainly used in hybrid power vapour
Car and other need the occasion of high current charge-discharge.According to the difference of internal material, lithium-ion-power cell group is accordingly divided into
Liquid lithium ion power battery pack and polymer lithium ion power cell group two kinds, be referred to as lithium-ion-power cell group.

Lithium-ion-power cell group is made up of multiple lithium-ion electric cores, depending on particular number can be according to being specifically related to specification,
For improving overall power and the capacity of lithium-ion-power cell group, need to use a lot of single lithium-ion electric core to constitute lithium ion and move
Power set of cells；In actual use, substantial amounts of lithium-ion electric core is in charge and discharge process, especially during fast charging and discharging all
Can highly exothermic, cause lithium-ion-power cell group internal temperature raise, overheated, hydraulic performance decline, damage, even explode,
The danger such as spontaneous combustion；The lithium-ion-power cell group design of prior art, can not make lithium-ion-power cell group internal the most scattered
Heat, keeps the equilibrium of lithium-ion-power cell group overall thermal；
Additionally, in the lithium-ion-power cell design of high power and high power capacity, substantial amounts of single lithium-ion electric core need to be used,
From the point of view of existing wire laying mode is to single lithium-ion electric core, the single lithium-ion electric core in being grouped for same lithium-ion electric core comes
Saying, the length of the lead-in wire used also is obvious difference, owing to lead-in wire is a kind of metal material, per se with certain resistance,
The length difference of lead-in wire will cause the actual output current of single lithium-ion electric core in the packet of same lithium-ion electric core different, thus
Affect lithium-ion electric core packet, lithium-ion electric core combo and the overall performance of lithium-ion-power cell group.
In view of this, special proposition this utility model.
