Description
Technical field
This patent is related to the battery core of electric storage device, specifically, being a kind of battery core of electric storage device for capableing of high efficiency and heat radiation
Structure.
Background technique
Battery core is the basic unit of electric storage device.
In the battery core use process for the electric storage device being made of pellet electrode and diaphragm, in the prevalence of asking for self-heating
Topic, and the work of battery core generally requires just to be able to maintain higher efficiency and performance and service life in certain temperature range, for this purpose,
Battery core must have preferable heat-exchange capacity, it may be assumed that when self-heating needs to radiate, its own internal heat can be smoothly
Be transmitted to outside, when own temperature is lower to be needed to heat up, external heat can swimmingly be transmitted to therein.
Currently, radiator structure discloses more for electric storage device such as battery pack.But for forming electric storage device
Basic unit, that is, battery core for, thermal diffusivity but rarely has people's consideration.
By taking lithium battery as an example, in battery high power discharge, the battery core of inside battery is due to chemical reaction and internal resistance etc.
The heat of generation, be to external diffusion, in order to avoid lead to thermal runaway since temperature is excessively high.Conventional structure is shown in Figure 1, piece
The anode 1 of shape, diaphragm 2, the battery core arranged at equal interval of 3 diaphragm of cathode 2, the thickness side that electrode heat passes through the material of composition battery core
To (in figure shown in arrow), transmitting outward from level to level, due to including insulating materials in the material composition of battery core, along material
The thermal resistance of thickness direction is very big, and the temperature difference of the battery core from center to outer surface is big, and heat transfer is unsmooth, to influence the energy of battery core
Power plays, and also results in the uneven of internal temperature of battery, will have a direct impact on working performance and the service life of material, cause in battery
The performance rapid decay of the part in portion, influences that battery life is short, and in addition safety is poor.
Summary of the invention
The purpose of this patent is to provide a kind of core strueture of the electric storage device of high efficiency and heat radiation, it can improve the heat of battery core

Electric storage device.
This patent the utility model has the advantages that the innovation structure is the anode and/or cathode for the battery core that will be constituted, with as big as possible
Area extends and connects on external heat dissipation pole plate, and since electrode material has the good capacity of heat transmission, which makes heat
Heat dissipation pole plate is quickly transmitted to along electrode material, external system can carry out heat management to electric storage device by heat dissipation pole plate, can
Influence of the nonmetallic materials to heat transmitting in battery core is greatly reduced, improves the heat-exchange capacity of battery core, significantly improves storage
Electric installation internal temperature equilibrium degree makes the operating condition basis equalization of material, can extend the service life of electric storage device, improve battery core
Safety can be improved simultaneously in thermal balance ability.
The electrode heat sink can both be used only as heat dissipation and (need that the electricity being connected with electrode is in addition arranged under the state
For pole piece for being electrically connected, this is routine techniques state, is not required to illustrate herein), it can also be used simultaneously as the electrode of electric storage device.
The electric storage device refer to be made of thin electrode and diaphragm etc. can store electricity device, such as various lithium ion batteries,
Super capacitor etc..It can also include insulating layer, electrolyte, various additives etc., this category in the composition of the electric storage device
In the prior art.The diaphragm quantity of the electric storage device and setting do not influence the protection scope of this patent.
The diaphragm, either independent film, be also possible to adhere on some electrode has certain insulation
The film of ability (ability of isolation electronics or ion).
The radiator structure is also possible to any one either being connected to different heat dissipation pole plates when positive and negative electrodes in same
Electrode is connected to heat dissipation pole plate.
