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 nano tube conductive paper is the ultrathin lithium ion paper battery of negative pole.
Background technology
Paper battery is ultra-thin battery, can embed in paper, is desirable compact power.Paper battery once uses and chargeable two class batteries.The part of this novel battery comprises electrode, electrolyte and barrier film.This paper battery can fold, and can produce by mode of printing, 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 nano tube conductive paper while as negative pole and the afflux utmost point.The structure of battery is further simplified than common paper battery.
The present invention is achieved by the following technical solutions.
Ultrathin 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 carbon nano tube conductive paper, after vacuumize, stacks by barrier film (3) and anodal active material face, then packs envelope in fact with aluminum plastic film, after vacuumizing, injects electrolyte, sealing.Two lugs remain on package outside, as positive and negative electrode tie point.
The thickness of ultrathin lithium ion battery of the present invention is no more than 0.5mm, and application is very extensive.Can be used for the fields such as smart card, music greeting card, electronic tag, electronic newspaper, RF Reader (RFID).
