Description
Technical field
The present invention relates to the rechargeable type lithium battery, particularly have electrolytical lithium battery of self-viscosity high-molecular and manufacture method thereof.
Background technology
In recent years, rechargeable secondary battery is after releasing, because it is manufacturing sure that its performance is subjected to portable type electronic product, for this reason, the application product specification of this battery and quantity all increase fast, the product that adds electronics, information and communications industry etc. all strides forward towards more frivolous, short and small practical design aspect, and the characteristic of the power supply that every required by electronic product is asked---secondary cell and function have become the decisive key factor of product competition advantage.
General TunePower just/coating and the assembling mode of negative plates be with just/negative electrode active material with just becoming/negative material after polymeric adhesive, assistant director of a film or play's agent etc. mixes, coat on the collector plate with coating machine again, its coating pattern as shown in Figures 1 and 2.Fig. 1 is the interruption coating method of homogenous material, Fig. 2 then is the continuous coating method of homogenous material, coating after finishing just/negative plates 10a, 10b through roll, behind the itemize, by the macromolecule barrier film it is separated, carry out again circular roll around with the ellipse electrode roll around after, after through other postorder actions of putting into circle or square metal shell 21 etc., pour into liquid electrolyte again, promptly finished making circular and rectangular cell.
Owing at present electronic product is required to compact, so the design of rechargeable secondary battery is promptly more harsh than in the past with the requirement in the space utilization to battery weight, energy density.Development with secondary cell, early stage secondary cell be configured to circular structure, as shown in Figure 3, above-mentioned anode plate/macromolecule barrier film/negative plates is carried out circle and square pole plate reels after 20, put into circle or square metal shell 21, this kind circular structure comparative maturity on engineering, but, will cause the weight of battery to increase because shell is a metal can.Therefore development in future trend will be the package casing of battery with the aluminum foil material, to reduce the weight of battery.
For these reasons, the packaging technology of battery mainly contains piles up and the coiling dual mode, the cell stacks mode of promptly so-called similar present stage macromolecule battery (U.S.'s Bell Laboratory), as shown in Figure 5.The battery that is formed by the mode that laminates pole plate 30 can reach closest packing in theory, and just its space availability ratio maximum adds and utilizes aluminium foil shell 31 packings, can reduce overall battery weight, can reach the purpose that improves energy content of battery density in theory.But because in the design of current battery, without any cementability, therefore present rechargeable battery (Ni-MH battery, lithium ion battery) all can't be prepared to pile up the pressing mode between electrode pad and the macromolecule barrier film (PE, PP or nonwoven fabrics).
Macromolecule battery then because its polyelectrolyte membrane (similar barrier film) has bigger adherence, therefore can pile up pressing.But pole plate needs and polyelectrolyte (film) pressing is piled up, therefore just need be increased in/polymeric adhesive consumption on the negative plates, and just make/ratio of active material on the negative plates reduces, the weight energy density that causes macromolecule battery is on the contrary less than lithium ion battery, and since just/after polymeric adhesion agent content on the negative plates increases, just/the electron conduction degree of negative plates decreases, and causes the charge/discharge of macromolecule battery to be difficult for carrying out.Therefore, need not increase under the prerequisite of polymeric adhesive, how can just carry out in the closeest in theory pressing mode of piling up/negative plates and macromolecule barrier film are superimposed, are the current required major issues that overcomes.
As everyone knows, attempted adhesive application professional technique on battery pole plates, it can make the problems referred to above be resolved, but because the macromolecule battery processing procedure of stack, more inequality with the process design of present lithium ion battery, and the production of the macromolecule battery processing procedure of stack and the techniques of mass production popularize as yet ripe, so be badly in need of on the market a kind ofly can and making the new processing procedure of compact battery with existing process-compatible.
Summary of the invention
An object of the present invention is to provide a kind of manufacture method with the electrolytical lithium battery of self-viscosity high-molecular, it makes the making of battery not single close with existing coiling processing procedure, and the macromolecule battery processing procedure that can contain stack, and this manufacture method can with existing battery process-compatible.
Another purpose of the present invention provides a kind of macromolecule battery that had not only had viscosity but also high-energy-density can be provided.
In order to achieve the above object, the present invention mainly is after the solution perfusion that will contain polyacrylonitrile (PAN) enters in the pole plate of battery and the barrier film, pours into organic solvent again and the polyacrylonitrile solution that is gluey is originally produced be separated and obtain pole plate and the bonding battery of barrier film.
The invention is characterized in macromolecule polypropylene nitrile heating for dissolving in solution, be in molten condition or mobile big when liquid at the solution of pbz polymer polyacrylonitrile, it is quantitatively poured into the battery pole coil of coiling or the battery pole plates that piles up in; After treating its cooling, add organic solvent again, originally the polyacrylonitrile solution that be colloidal state this moment will produce phenomenon of phase separation, polyacrylonitrile will be separated out with polymeric membrane or bulk, therefore can allow battery pole coil or push away folded battery pole plates and be bonded together, and this bonding program is very high with present lithium ion battery process-compatible, thereby can reach above-mentioned purpose of the present invention.
Solution of the present invention is ethylene carbonate (EC) or propene carbonate (PC), or above-mentioned two kinds mixed solution.
And described organic solvent is a kind of diethyl carbonate (DEC), dimethyl carbonate (DMC), methyl ethyl carbonate (EMC), ethylene carbonate, propene carbonate, butylene, γ-Ding lactones, dimethoxy ethane, oxolane, 2-methyltetrahydrofuran and vinylene carbonate (ViayleneCarbouate) solvent or above-mentioned two or more at least mixed solvent of being selected from.
Because the electrochemical reaction of battery itself need contain a large amount of ions and finish, thus described solution and organic solvent both one of or above-mentioned both contain lithium salts, for example LiPF simultaneously
