Pond upper cover 4, the cell cover are equipped with liquid injection hole 42 and exhaust valve 43；It is additionally provided with positive electrode 41 on cell cover, bears
The fixture 45 of electrode 44 and fixed battery core 3；Battery case described in the present embodiment is metal material, accelerates heat dissipation effect
Fruit；Demarcation plate described in the present embodiment is plate-type heat-pipe, and plate-type heat-pipe two sides is metal material, and there be the thermally conductive of flowing in inner cavity
Liquid can quickly conduct heat.
Lithium ion battery structure described in the utility model is by multiple battery compartments, multiple battery roll cores, multiple batteries
Lid and injection chamber intracorporal electrolyte composition, core and corresponding electrolyte obstruct independently of each other in battery compartment, plate-type heat-pipe with
Core and corresponding electrolyte uniformly contact, and the heat that battery generates when working can be conducted rapidly by multiple plate-type heat-pipes, make electricity
Pond temperature uniformity, and battery case body can be conducted heat to, it is evacuated away by external heat-exchange system, with effectively
Control battery temperature.
The above embodiments are merely examples for clarifying the description, and does not limit the embodiments.For institute
For the those of ordinary skill in category field, other various forms of variations or change can also be made on the basis of the above description
It is dynamic.There is no necessity and possibility to exhaust all the enbodiments, and obvious variation extended from this or change
Within the dynamic protection scope created still in the utility model.
