The important development direction of management system；Common liquid cooling mode is to spread to dissipate pipeline inside battery bag, so can compare and account for
With inner space it is most important that liquid cooling inside battery bag using exist leakage major safety risks.
Meanwhile, the battery production efficiency high of traditional winding-structure, pole piece corner area little it is easy to mass production and pole piece
Burrs on edges, the effective control of shedding；The charging, discharging electric batteries multiplying power of the continuous winding of traditional multi-winding-core is higher, and quantity of heat production is little, adapts to
The use under cryogenic conditions under certain limit；But pole piece corner area is larger, and production efficiency is relatively low, is unfavorable for mass
Produce and pole piece burrs on edges, the control of shedding.
The shortcoming of traditional ultrasonic welding structure has：Usually less than 100 layers of the soldering polar ear number of plies, and the height that moment produces
Temperature easily causes the ceramic-coated separator paper at lug to shrink, and forms potential safety hazard；Ultrasonic equipment maintenance is difficult, and its rosin joint produces
Product are difficult to be aware, and affect battery with two side terminals, are unfavorable for follow-up battery combo and assembling；Easily cause lug cracking or produce
Raw metallic dust, the safety of impact battery.
The shortcoming of traditional stud draw bail has：The size material of stud is limited by technique, by battery shell-space
Impact, the diameter of stud is restricted, and in order to improve torsion, generally adopts rustless steel stud, because it is connected with cover plate of outer casing
Post material is different and form galvanic element, easily live hot spot, the reliability of impact battery；Stud connection torsion less it is impossible to gram
Clothes are negative, the impact to contact resistance such as negative plate lug, cover plate of outer casing connecting post material surface roughness, and its contact surface resistance is not
Stable, affect battery with two side terminals, be unfavorable for follow-up battery combo and assembling；
Its technology controlling and process complexity is welded in laser penetration, is affected by factors such as environment, material, techniques, its soldering polar ear layer
Number generally need to control below 10 layers, and welding effect extremely unstable.
Lithium battery is because running voltage is high, energy density is big, memory-less effect, have extended cycle life, pollution-free the advantages of,
It is applied to more and more widely in consumption, power, energy storage and various uses battery, progressively instead of traditional rechargeable battery and become
Major product for field of batteries.With the expansion in market, also more next to the demand of large-capacity high-power lithium ion secondary battery
Bigger, the such as mobile communication base station of back-up source class, the peaking power source of wind and light generating system, car lithium battery bag, frigid zone first aid
All there is very big demand in the market such as stand-by power supply and frigid zone electric motor car power supply of speedily carrying out rescue work.Require battery cell capacity big, power is close
Degree is high, concordance good it is easy to combo, battery bag at -30 DEG C～+60 DEG C,（1—10）Under C discharge-rate, remain to negative often work,
Its conventional 100Ah and above high-capacity lithium-ion secondary cell have the following defect being difficult to and going beyond.It is mainly reflected in：
1）The battery of ultrasonic bonding, the internal resistance of cell dispersion of different platform and time welding is big, is unfavorable for joining of battery bag
Group；
2）The internal resistance of cell that stud even joins is big, and the continuous discharge being generally only suitable for the following electric current of room temperature 1C is it is impossible to meet equipment
Required high power requires；
3）The internal resistance of cell of stud even connection is big, such as 50Ah lithium rechargeable battery 1KHz AC impedance generally in more than 1m Ω,
Discharge-rate is poor；
4）Shell is typically directly turned on negative electrode, battery in groups after, casing insulation layer rupture, cause short between Cell in set of cells
Road or shell are by the security risk of chemical attack.
5）Under the conditions of battery high current charge and discharge, temperature rise is higher, has a strong impact on the cycle life security performance of battery.
