Present lithium ion battery; Constantly reach the needed thickness requirement of equipment, wherein mainly concentrate on improvement and design, be compounded with adhesive on the barrier film at present the barrier film of battery inside through material and the structure of improving battery; Can make battery have the higher intensity and the security performance of battery; But also correspondingly caused the conductivity reduction, the cycle life of battery lowers, and has influenced the overall performance of battery.Usually adopt common material and complicated structure like present thin polymer lithium ion battery; Chinese patent numbers 200520064204.8; " lamination of the battery of lithium ion battery " disclosed; Its structure is as shown in Figure 1, but owing to adopt this structure of " Z " font that the barrier film number of plies is reached more than 5 layers, cell thickness can not satisfy the demand of equipment; Chinese patent numbers 200810305705.9 discloses " a kind of composite cathode material lithium ion battery "; Its structure is as shown in Figure 2; Lithium ion battery adopts the structure of bagged film, and membrane layer has also reached 3 layers, and its technical difficulty hand-manipulated is higher; Make cell thickness more than 0.3mm, its thickness has still satisfied not the demand of special industry.
Summary of the invention
1. the technical problem that solves of utility model
To the improvement of the inner barrier film of battery in the existing lithium ion battery and the deficiency of design; The utility model provides a kind of ultra-thin novel polymer lithium ion battery; It is simple in structure, thickness can satisfy the special industry demand, and the overall performance of its battery is superior simultaneously.
2. technical scheme
A kind of ultra-thin novel polymer lithium ion battery; Comprise monofilm positive plate, anode ear, barrier film, monofilm negative plate, negative electrode lug, plastic-aluminum rete and blue adhesive tape; Monofilm positive plate and monofilm negative plate are superimposed up and down to constitute the monomer of battery in both sides at barrier film; Face is relative, the alignment of pole piece left-right and front-back, and fixes through blue adhesive tape, is surrounded by the aluminum plastic film layer outward.
Barrier film is the ultra-thin barrier film of individual layer, and thickness is 0.016mm.
The thickness of monofilm positive plate, monofilm negative plate is 0.050mm.
The thickness of blue adhesive tape is 0.009mm.
3. beneficial effect
Compare with common material and other combining structure; The utility model adopts battery inner septum structure optimization design; Provide a kind of simple in structure, thickness reduces and can satisfy a kind of ultra-thin novel polymer lithium ion battery of special industry demand; At inner this structure, the thinnest 0.285mm that reaches of cell thickness of adopting of polymer Li-ion battery.
