Description
Technical field
With market development, the needs of industry, the guide of national policy, to the high rate performance and energy of power lithium-ion battery
Metric density requires higher and higher.The development plan of power battery: the year two thousand twenty, the energy content of battery is specified according to " made in China 2025 "
Density reaches 300Wh/kg；2025, battery energy density reached 400Wh/kg；The year two thousand thirty, battery energy density reach
500Wh/kg.Soft bag lithium ionic cell (polymer Li-ion battery, be with aluminum plastic film shell liquid lithium ionic cell) due to
Shell is thin, and material is light, dominant in terms of energy density.But the shell of Soft Roll polymer Li-ion battery is aluminum plastic film, aluminium
Plastic film outermost layer and innermost layer and internal adhesive layer are the non-conductor of heat, and soft-package battery is caused to be unfavorable for heat dissipation and add
Heat is unfavorable for the heat management of battery modules and battery system, and temperature field is uneven, and with the increase for filling, putting the time, temperature is high
Higher and higher, the inconsistency for accelerating battery deteriorates, and temperature height is to a certain degree to the service life of battery system and safety shadow
Sound is bigger.
Summary of the invention
It is an object of the invention to use with a kind of solid phase heat, one is established from battery core inner straight battery core shell
Heat transfer path, realization actively or passively carries out heat management, and then realizes that the highest of lithium battery mould group, minimum and temperature field are consistent
Property.
To achieve the above object, the invention adopts the following technical scheme: a kind of lithium ion battery heat-transfer device, including electricity
Core, battery core bracket, the tab connecting with battery core and battery core shell, further include heat-conducting plate, and one end of the heat-conducting plate and tab connect
It connects, the other end and battery core cage connection of heat-conducting plate form heat transfer between the battery core, tab, heat-conducting plate and battery core shell
Channel, the battery core shell form heat accumulation room as heat transfer terminal.
Preferably, the heat-conducting plate includes heat-conducting plate one and heat-conducting plate two, and the heat-conducting plate one connects adjacent tab,
One end of the heat-conducting plate two is connect with heat-conducting plate one, the other end and battery core cage connection.
Preferably, the battery core outer side of shell is equipped with electric heater unit.
Preferably, the heat-conducting plate is silica gel heat-conducting plate.
Preferably, the heat-conducting plate is insulated metal heat-conducting plate.
Preferably, the electric heater unit is resistance heating, induction heating, electron beam heating, infrared heating or medium
One of heating.
Preferably, high-temperature resistant rubber has been wrapped on the fire end in the electric heater unit.
Compared with prior art, the present invention is in lithium battery mould group charge and discharge process, soft pack cell inner pole piece and diaphragm
The heat of upper generation passes to positive and negative anodes tab by battery core positive and negative anodes collector, the heat on positive and negative electrode tab by with its
The heat-conducting plate of connection, and battery core shell is transferred to by heat-conducting plate, the electricity made in entire mould group is led by the anti-pass of battery core shell
The temperature field of core is rapidly reached equilibrium, and heat-conducting plate is directly connected to battery core shell, and shell controls battery core at a heat accumulation room
Temperature is in a certain range；Battery core is too high or too low for temperature in mould group in order to prevent, can also be using heat management device to battery core
Shell carries out heat management, when battery core when the temperature is excessively high, that is, when battery core skin temperature is excessively high, pass through what is be connected with battery core shell
Heat management device goes out heat transfer；Similarly when the temperature is too low, heat management device transfers heat to battery core shell, outside
Shell transfers heat to the positive and negative anodes tab of battery core by heat-conducting plate, and positive and negative anodes tab is again positive and negative anodes inside heat transfer battery core
Active material, electrolyte etc. realize temperature control.
