Abstract
The invention discloses a water-based conducting resin for a lithium ion battery. The water-based conducting resin is characterized by consisting of the following components by mass percent: 1-5 percent of 8-Hydroxyquiuoline, 25-45 percent of graphite, 15-30 percent of acrylic acid copolymer, 0.5-3 percent of flax oil, 5-20 percent of isopropyl alcohol, 1-5 percent of KH560 and water, and the total mass percentage is 100. The water-based conducting resin has the advantages of environmental protection, high charge-discharge frequency, and easiness in embedding and removing ions.
Description
Technical field
The invention belongs to technical field of adhesive, relate to a kind of waterborne conductive glue for lithium ion battery, specifically relate to one and put a number of times for improving anode material for lithium-ion batteries LiMnO2 charging, improve, improve the adhesive of the corrosion resistance of electrode.
Background technology
Adhesive is one of critical material of lithium battery, it has important impact to distribution and the battery performance of anodal and active material, the optimal distribution of conducting resinl should be to be coated on anodal particle surface, continuous with active material contacts, thin as much as possible, make electronics can arrive whole active particle surface, lithium ion is more easily embedded under less overpotential and deviate from active particle.The Kynoar (PVDF) that the adhesive using is at present hydrophobicity, it is harsher to workshop condition conditional request, has strengthened the cost of investment in workshop; Its solvent using is 1-METHYLPYRROLIDONE (NMP).NMP not only price is more expensive, has improved battery cost, and has certain toxicity, heating volatilization can cause environmental pollution, can not make active material distribute and reach perfect condition, affect embedding and deviate from from positive electrode of lithium ion, affected the number of times discharging and recharging simultaneously.Need to develop one environmentally friendly, and low price, active material is distributed desirable, discharge and recharge the waterborne conductive glue that number of times is high.
Summary of the invention
The object of the invention is, in order to solve conducting resinl environmental protection, to improve the number of times that discharges and recharges of lithium ion battery, improve the decay resistance of electrode, the technical problem that extends the useful life of battery, provides a kind of waterborne conductive glue for lithium ion battery.
In order to achieve the above object, the technical scheme that the present invention takes is:
A kind of waterborne conductive glue for lithium ion battery, content is 1-5% by 8-hydroxy-quinoline by mass percentage, graphite is 25-45%, acrylic copolymer is 15-30%, linseed oil is 0.5-3%, and isopropyl alcohol is 5-20%, and KH560 is 1-5%, surplus is water composition, and gross mass degree is 100%; Wherein said acrylic copolymer molecular structure is:
Wherein, n is 20-100 integer, the integer that n2 is 20-40, and the integer that m is 30-100, the integer that m1 is 1-3, its weight average molecular weight is 10000-50000.Its product derives from hydroxy-ethyl acrylate, butylene olefin(e) acid or penetenoic acid and to vinyl benzoic acid copolymer.
The preparation method of a kind of waterborne conductive glue for lithium ion battery of the present invention is: first the liquid component of technical scheme is mixed, then add solid constituent to stir, then grind on grinder, finally packaging.
Advantage and the beneficial effect of the waterborne conductive glue for lithium ion battery of the present invention are:
1, environmental protection, coating is thinner is 5 μ m, conductance square resistance is 30 ohm;
2, discharge and recharge number of times high, ion easily embeds and deviates from.
