The purpose of this utility model is in that the deficiency for existing lithium battery, it is provided that the new type of safe lithium battery of a kind of stability height, simple in construction, cost performance height and life-span length.
To achieve these goals, this utility model have employed techniques below scheme:
A kind of new type of safe lithium battery, including lithium battery electric core, circuit board and shell, it is characterized in that: the electrode ear of described lithium battery electric core uses circuit board to link together respectively, lithium battery electric core and circuit set in the enclosure, being provided with sealing coat between lithium battery electric core and shell, sealing coat is wrapped in lithium battery core outer surface; The electrode ear of described lithium battery electric core is higher than sealing coat.
Described lithium battery electric core is soft battery, and soft battery is for being arranged in parallel, and soft battery is more than ten joints.
Described shell is aluminum or copper product is made.
Described sealing coat is the material layer of elastic high insulating heat-conductive, and the material layer of elastic high insulating heat-conductive includes silica gel material layer.
The beneficial effects of the utility model:
This utility model arranges a layer sealing coat by the space between lithium battery Soft Roll and shell, sealing coat plays to take and is constrained in by a number of lithium battery electric core in a little space, then pass through the colloidal substance of high insulating heat-conductive and be filled between lithium battery electric core and the space of lithium battery electric core and shell, play isolating lithium battery battery core and air contact, thus preventing lithium battery electric core from causing burning because of fault. Meanwhile, the colloidal substance of employing has certain elasticity, can provide the buffering of certain mechanical vibration for lithium battery electric core, vehicle-mounted application be brought benefit, it is ensured that the stability of lithium battery electric core, extend the life-span of lithium battery electric core.This utility model has the advantage of stability height, simple in construction, cost performance height and life-span length, and this utility model is widely used in field of batteries.
