Radiating so that in use, temperature is consistent between battery core for battery；The outer only one of which battery case of soft pack cell, in shell
Space is left, battery core can be prevented to expand with heat and contract with cold.
As a further improvement on the present invention, the battery cover group is by the glass mat, rustless steel for arranging from top to bottom
Plate and insulation board composition, are provided with escape orifice on the corrosion resistant plate；The escape orifice is manhole, and quantity is 4 ~ 10,
Long side along corrosion resistant plate is equally spaced, and when battery receives extruding or external force is punctured, relief hole can be released in battery
Gas.
As a further improvement on the present invention, glass mat upper end is provided with positive terminal and negative terminal, negative terminal
Using quadrilateral structure, during use, contact better with double buckle, so as to ensure that equipment is continuously powered.
As a further improvement on the present invention, terminal is all offered on the glass mat, corrosion resistant plate and insulation board
Location hole, for riveting and fixing positive and negative terminal.
As a further improvement on the present invention, the battery cover group and battery case are fixed on by laser welding or buckle
Together；Battery case includes that housing and lower cover, the housing and lower cover are formed in one.
As a further improvement on the present invention, the voltage of the soft pack cell is 3V.
The beneficial effects of the utility model：
1. Heat Conduction Material is coated between the battery core in battery, and heat is mutually transmitted, and makes each battery core temperature identical, from
And ensure that battery each battery core electric discharge is consistent, performance is consistent.
2. using the lithium battery of soft pack cell, in the case where there is potential safety hazard, soft-package battery is at most only understood air-blowing and is split,
And blast can occur unlike other battery cores.
3. cell cover plate is provided with bleed outlet, and battery is subject to release when external force puncture, extruding or high temperature sintering
Gas in battery, it is safer.
4. possess that security performance is high, lightweight, internal resistance is little, capacity is big, temperature resistant range is wide using the lithium battery of soft pack cell,
The advantages of exquisite appearance, it is more suitable for using, deposit and transporting.
5. combined using soft pack cell, whole cell safety reliability, the connection of each several part part is more compact, and structure is more reliable,
