Abstract
The utility model discloses a curved surface type battery which comprises a flexible housing, a cell, a negative electrode and a positive electrode, wherein the cell is packaged in the flexible housing, the negative electrode and the positive electrode are connected with the cell and penetrate out of the flexible housing, and the cell is of a curved surface. The cell of the curved surface type battery is of the curved surface, and the flexible housing is packaged outside the cell, so that the curvature of the cell can be regulated to any value from 20 DEG to 152 DEG according to different electronic products, and thus the radian of the curved surface type battery can be applicable to different electronic products.
Description
Technical field
The utility model relates to a kind of curved face type battery.
Background technology
Lithium ion battery is a kind of rechargeable battery, and it mainly relies on lithium ion mobile generation current between positive pole and negative pole.During charging, lithium ion, from the de-embedding of positive pole, embeds negative pole through electrolyte, and negative pole is in rich lithium state; Opposite during electric discharge.The general employing contained the battery of the material of elemental lithium as electrode.It is the representative of modern high performance battery.
The shape of lithium battery is mainly cylindrical or square at present, it can meet electronic product such as panel computer or the mobile phone of traditional design, but the development along with economic civilization, the design of many electronic products is no longer just to improving performance, mostly is to give product fashion characteristic, for example smart mobile phone is designed to the wrist-watch shape, for the electronic product of this type of unique shape, the shape of current lithium battery and structure often can't be suitable for.
The utility model content
For the deficiencies in the prior art, the purpose of this utility model is intended to provide a kind of curved face type battery that can solve the problems of the technologies described above.
For achieving the above object, the utility model adopts following technical scheme:
A kind of curved face type battery, it comprises soft shell, battery core, negative electrode and positive electrode; This battery core is packaged in this soft shell, and negative electrode is connected battery core and passes this soft shell with positive electrode, and this battery core is the curved surface shape.
This battery core comprises anodal basic unit, negative pole basic unit, the first separator and the second separator; Anodal basic unit is between the first separator and the second separator, and the first separator is between anodal basic unit and negative pole basic unit, and this electric core winding is hot pressed into curved surface plates; Positive electrode connects anodal basic unit, and negative electrode connects negative pole basic unit.
This battery core comprises from top to bottom anodal basic unit, separator and the negative pole basic unit of stack successively; Positive electrode connects anodal basic unit, and negative electrode connects negative pole basic unit.
Positive electrode and negative electrode are positioned at the same end of battery core.
Positive electrode and negative electrode are positioned at two relative ends of battery core.
The beneficial effects of the utility model are as follows:
The battery core of above-mentioned curved face type battery is the curved surface shape, and its outer package soft shell, makes its curvature can be adjusted into according to different electronic products 20 arbitrary values of spending in spending to 152, so that the radian of this curved face type battery is applicable to different electronic products.
The accompanying drawing explanation
Fig. 1 is the schematic diagram of preferred embodiments of the battery core of the utility model curved face type battery.
Fig. 2 is the generalized section of the battery core of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described further:
