Description
Technical field
The application is related to cell art, especially a kind of battery modules and high capacity cell, particularly a kind of cylinder
Shape lithium ion battery module and the column lithium ion high capacity cell being made up of multiple this battery modules.
Background technology
Lithium-ion rechargeable battery is that the most long battery of service life, its technology is ripe currently than energy highest, raw
Yield is huge, has entered into the every field of people's lives.Existing column lithium ion battery module generally comprises all insulation material
Matter and open up thereon the battery clamp of numerous battery plug-in openings, the numerous batteries being respectively embedded into each battery plug-in opening series connection
A parallel-connection network of connection is contacted in piece while embedded each battery plug-in opening and with each battery series connection piece, is plugged in respectively
The numerous battery cells for being connected in each battery plug-in opening and with corresponding battery series connection piece and (directly contacting connection or welding).It is actual
Using when, these battery cells by foregoing parallel-connection network it is parallel with one another, by it is foregoing series connection piece with insertion battery clamp opposite side
Battery cell realize series connection, so multiple battery modules are fitted together and form the lithium ion battery of Large Copacity.
But some deadly defects of lithium ion battery module do not solve thoroughly fundamentally, such as security, have still had
Hot fried danger.The engineers and technicians for being engaged in the sector are taking many kinds of measures to eliminate this danger.Such as China is specially
A kind of battery connection mechanism is proposed in profit application CN101369649A, the negative pole of cylindrical battery is clamped with a kind of flexible connection piece
Shell realizes electrical connection, and so as to eliminate the welding processing to negative pole, eliminating sweating heat may be to caused by battery core component
Injury.Security is not only increased, and improves the processing characteristics and rigidity of battery pack, more suitable for mechanized operation.
The Cologne group of Henan in 2012 it is also proposed similar patent, illustrate the validity of the method.But the spring leaf of the method
Contact is few, and resistance still dislikes big.Moreover, inconvenient to external expansion, radiating is also undesirable.
At present most enterprises do battery assembling method be still with the both positive and negative polarity of thin metal connecting sheet and battery welding,
Reach series connection and parallel connection.Connection sheet is very thin, narrow and long, and conductive capability is poor, and connection resistance is high, and energy consumption is big.And energy consumption switchs to send out
Heat, battery temperature is promoted to rise.Temperature raises the service life that can shorten battery.Let alone the potential danger that negative pole welded bands are come
Danger.
Many good methods are also createed in order to improve the heat-sinking capability of battery.Such as Zhang Hengyun etc. is in Chinese patent Shen
It please propose to add heat conducting sleeve and heat conducting pipe to battery in CN201610144883.2, and be arranged heat with temperature adjustment gas or liquid
Go out.Make the battery of the diverse location maximum temperature temperature difference in large current charge narrow down to only 1.5 DEG C of it is ancient shine grand grades it is Chinese specially
It is proposed to irrigate heat-conducting glue in battery pack also have good effect in profit application CN2009102097104.
Wang Huaiyun is proposed in Chinese patent application CN201220400944.4, is inserted with the stretched multiple batteries of metal sheet
The framework in parallel in hole, jack peripheral band elastic claw self-contained battery negative pole, realizes more cell parallels.Not only easy to connect and thermal conductivity
Well.
Combination connection is done with connection sheet welding both positive and negative polarity, connection resistance is high.Especially negative pole is welded, sweating heat passes to electricity
Inside pond, there are the core components such as barrier film pole plate close to weld, all To Be Protected from Heat for they.If they are scalded, it is possible in use
Develop into internal short-circuit.And internal short-circuit has the danger for being converted into thermal runaway, thermal runaway is to cause the major reason for blast of catching fire.And
And the component welded with connection sheet is loose, mobile difficult in operation, big part is more difficult to process, and is not suitable for do mechanization operation.
Negative pole is eliminated with the method for spring leaf (with the series connection piece for playing pawl) to weld, but it is outside with dovetail and dovetail groove
Extend pretty troublesome, and it is not so good to radiate.Add the radiating effect of heat conducting sleeve heat conducting pipe and heat-conducting glue fine, but these adapters remove
Temperature adjustment improves cost and complexity without other use.Porous parallel-connected framework is not only conductive good but also good heat dissipation, but tens
Hole punching press simultaneously, stretching, processing difficulties.And because structure limits, elastic claw is very short, therefore elastic force is difficult control, insertion
Battery is also easily crooked.
