Abstract
An ultrathin lithium ion battery is composed of an anode mass flow electrode (1), an anode active material (2), a diaphragm (3), a cathode (4), a cathode tab (5) and an anode tab (6) and is characterized in that the cathode is carbon nanotube conducting paper. The thickness of the ultrathin lithium ion battery provided by the invention is no more than 0.5mm. The ultrathin lithium ion battery has a very extensive application range and can be used in the fields such as intelligent card, music greeting card, electronic tag, electronic newspaper, RF Reader and the like.
Description
Technical field
The present invention relates to a kind of carbon nanotube conducting paper is the ultrathin lithium ion paper battery of negative pole.
Background technology
Paper battery is a ultra-thin battery, can embed in the paper, is desirable compact power.Paper battery once uses and chargeable two types of batteries.The part of this novel battery comprises electrode, electrolyte and barrier film.This paper battery can fold, and can pass through mode of printing production, a kind of novel energy storage device.
Summary of the invention
The present invention relates to a kind of with the chargeable lithium ion paper battery of carbon nanotube conducting paper while as the negative pole and the afflux utmost point.The structure of battery is further simplified than common paper battery.
The present invention realizes through following technical scheme.
Ultra-thin lithium ion battery of the present invention is made up of the anode collection utmost point (1), positive electrode active materials (2), barrier film (3), negative pole (4), negative lug (5) and anodal level ear (6).The anode collection utmost point (1) adopts aluminium foil, and surface-coated positive electrode active materials (2) final vacuum is dry; Negative pole (4) is a carbon nanotube conducting paper, stacks through barrier film (3) and anodal active material face after the vacuumize, packs envelope in fact with aluminum plastic film then, after vacuumizing, injects electrolyte, sealing.Two lugs remain on package outside, as the positive and negative electrode tie point.
The thickness of ultra-thin lithium ion battery of the present invention is no more than 0.5mm, and application very extensively.Can be used for smart card, music greeting card, electronic tag, electronic newspaper, RF Reader fields such as (RFID).
Description of drawings
Fig. 1 is the ultrathin lithium ion paper battery of the present invention structural representation.1 is the anode collection utmost point, and 2 is positive electrode active materials, and 3 is barrier film, and 4 is negative pole, 5 negative lug, and 6 is positive pole ear.
Embodiment
The present invention will be described further through following examples.
The preparation of carbon nanotube conducting paper is following among the said embodiment: CNT and dispersant SDBS are joined in concentration 50% ethanolic solution, and every liter of solution adds CNT 2-8 gram, SDBS addition 5-10 gram; After ultrasonic 10 minutes; Rice paper is deployed in the solution, continued ultrasonic 20 minutes, carbon nanotube adsorption be penetrated in the paper; Offset with twin rollers after taking out conductive paper vacuumize, be cut into the specification that needs.
The positive pole material lithium manganate slurry coating of living is processed positive pole on the aluminium foil as the anode collection utmost point, carbon nanotube conducting paper is put into barrier film and is assembled into paper battery as negative pole between the positive and negative electrode, vacuumizes after the encapsulation and injects electrolyte LiPF6, sealing then.
Positive pole material ferric lithium phosphate slurry coating alive is processed positive pole on the aluminium foil as the anode collection utmost point; Carbon nanotube conducting paper is as negative pole, puts into the barrier film assembling between the positive and negative electrode, vacuumizes after the encapsulation and injects electrolyte LiPF6; Sealing promptly makes ultra-thin lithium ion paper battery then.
The positive pole material of lithium cobalt acid slurry coating of living is processed positive pole on the aluminium foil as the anode collection utmost point, carbon nanotube conducting paper is put into barrier film and is assembled into paper battery as negative pole between the positive and negative electrode, vacuumizes after the encapsulation and injects electrolyte LiPF6, sealing then.
Claims (1)
