Abstract
The invention discloses a kind of flexible lithium ion battery and manufacture method thereof, flexible lithium ion battery includes sealed package and is arranged at the set of cells within sealed package and electrolyte, and described set of cells includes positive plate, negative plate and the isolating membrane being arranged between positive plate and negative plate;Set of cells side is provided with and connects the anode ear of positive plate and the negative electrode lug being connected negative plate, and described anode ear and negative electrode lug pass sealed package;Described electrolyte is filled in sealed package.The present invention passes through macromolecular material as fixation kit, it is filled in through hole after macromolecular material melts, the fastening macromolecular material again solidified after thawing is connected as a single entity after contacting with isolating membrane and sealed package, the effect of " skeleton " is served at inside battery, battery is in BENDING PROCESS, " skeleton " secures positive/negative plate and isolating membrane, so it does not occur significantly relatively to slide, it is to avoid pole piece damage and inside battery structural damage.
Description
Technical field
The invention belongs to field of batteries, be specifically related to a kind of flexible lithium ion battery and manufacture method thereof.
Background technology
High, the novel secondary battery of environmental protection as a kind of energy density, lithium ion battery is widely used in portable electric
The fields such as sub-product, electric automobile, energy storage.In particular with smart mobile phone in recent years, panel computer, super notebook computer with
And intelligence wearable device flourish, the market demand of lithium ion battery the most rapidly increases.
Along with fast development and curved surface, the popularization of flexible screen technology of intelligence wearable device, to supporting lithium ion
Battery product is had higher requirement---and flexibility, flexible.Conventional batteries is due to inherent structure feature, it is impossible to accomplish soft
Property is flexible: traditional duricrust battery, cannot bend including box hat, aluminum hull (square or cylindrical), and polymer battery (also known as
Soft-package battery, encapsulates with aluminum plastic film) although shell has certain deformability, but bending can cause internal structure (pole piece repeatedly
With barrier film) damage, performance with safety cannot ensure.
The Chinese patent of Application No. 201310746111.2 discloses a kind of flexible wearable lithium battery, and this flexibility is dressed
Formula lithium battery includes that battery module, described battery module include flexible software and battery core unit, and described battery core unit is by two
Above single battery core and for connecting the conductor composition of described single battery core, described flexible software and battery core unit pass through silica gel or soft
Property plastics integrated injection molding, it is by being encapsulated in one by single battery core of two or more small volume by silica gel or flexiplast
In individual flexible software, between single battery core by the way of serial or parallel connection, Optional assembling becomes battery module, and this battery module can
With bending, one or more battery modules can form again flexible wearable lithium battery easily.But the flexibility of this structure is complete
Entirely being provided by base material, the little battery core of double team itself does not possess flexibility, and it has the disadvantage that: have the disadvantage that:
1. energy density is low.The energy of whole battery only is from occupying more space in battery core part, flexible parent metal and implant,
Cause the energy density of whole battery significantly lower than the lithium battery commercially produced at present.
2. complex process efficiency is low.One inside battery needs to make multiple little battery core, also to have special between battery core
Conduction band connects.Packaging technology is complicated, and production efficiency is low.
3. flexible inadequate.Little battery core itself is without flexible, and little battery core may be caused more greatly by alternating bending or bending amplitude
Damage, affects electrical property and the security performance of battery.
Accordingly, it would be desirable to a kind of battery core of exploitation itself can bend, and the flexible battery that energy density is high, expand it further
Range of application, meets the highest use demand.
Summary of the invention
It is an object of the invention to provide to solve above the deficiencies in the prior art a kind of flexible lithium ion battery and
