Abstract
The utility model discloses a flexible lithium ion battery, including anodal pole piece, diaphragm, negative pole pole piece and flexible cell shell, negative pole pole piece length is greater than anodal pole piece length, and negative pole pole piece width is greater than anodal pole piece width, and anodal pole piece is located the middle part of negative pole pole piece, separates film length and is greater than negative pole pole piece length, and the negative pole pole piece is located unfamiliar middle part, and anodal pole piece, diaphragm, negative pole pole piece and flexible cell shell all are the wave type, does the diaphragm adopt PE PP PE three layer construction's diaphragm, the utility model discloses following beneficial effect has: do you use PE PP PE three layer construction's diaphragm guarantees that the diaphragm has good ductility in bending process, and just, the negative pole adopts asymmetric structure, the diaphragm can effectively cover the pole piece, effectively prevents the inside short circuit of pole piece at the in -process of the battery of buckling to the security of battery is greatly improved, adopt the wave type, for can the wide -angle is repeated on a face buckling, battery long service life can repeatedly buckle simple structure.
Description
Technical field
This utility model is related to lithium ion battery, and in particular to a kind of flexible lithium ion battery.
Background technology
Recently as the rise of portable intelligent electronic product, such as special-shaped mobile phone, intelligent watch, Intelligent bracelet, intelligence
Energy glasses, intelligent leather belt, the various wearable devices of intelligent headband and intelligent helmet etc., it can be connected with the Internet, by number
Powerful human-computer interaction function is realized according to exchanging, and these wearable equipment need to be carried out according to ergonomics or concrete application
Design；And at present conventional use of lithium ion battery mostly is flat rectangle or cylinder, but, rapid with wearable device is sent out
Exhibition, the battery of the flat rectangle or cylinder can not meet needs, in order to agree with more complicated and meet ergonomics
The needs of structure design, and wearable device space can be farthest utilized, at present the battery of flat rectangle does camber,
But arc battery manufacture is once extruded to shape for mould, it is impossible to bend and battery pole after bending is also easy to produce flatulence, internal short-circuit
There is larger potential safety hazard.
Utility model content
Technical problem to be solved in the utility model is to provide simple structure, convenient for production, can be according to setting for being applied
The novel flexible lithium ion battery that standby different bending radians are bent.
The technical solution for realizing this utility model purpose is：A kind of flexible lithium ion battery, including anode pole piece, every
Film, cathode pole piece and flexible battery shell, it is characterised in that：The cathode pole piece length is more than anode pole piece length, negative pole pole
Piece width is more than anode pole piece width, and anode pole piece is located at the middle part of cathode pole piece, and diaphragm length is more than cathode pole piece length, bears
Pole pole piece is located at the middle part of barrier film, and anode pole piece, barrier film, cathode pole piece and flexible battery shell are in undaform.
The barrier film adopts the barrier film of PE-PP-PE three-deckers.
This utility model has the advantages that：Using the barrier film of PE-PP-PE three-deckers, it is ensured that barrier film is in bending
During have good ductility, positive and negative electrode adopts unsymmetric structure, cathode pole piece length to be more than anode pole piece length, negative pole
Pole piece width is more than anode pole piece width, and diaphragm length more than the length of cathode pole piece, and barrier film can effectively cover pole piece, curved
Pole piece internal short-circuit is effectively prevented during folding battery, so as to substantially increase the safety of battery；It is energy using undaform
On one face wide-angle repeats to bend, and battery is long, repeats bending, simple structure.
Description of the drawings
Below in conjunction with the accompanying drawings this utility model is elaborated with embodiment；
Fig. 1 is a kind of structural representation of flexible lithium ion battery of this utility model；
