Embodiment
Battery provided by the invention is not only safe and reliable and have the longer life-span, and very convenient carrying and storage, as portable type electronic products such as mobile phone, notebook computers, and electric automobile, electric bicycle, the fields such as electric tool have considerable application prospect.
The present invention has disclosed a kind of battery, and battery comprises positive pole, negative pole and electrolyte, and electrolyte comprises electrolyte and can dissolve electrolyte and make the aqueous solution of electrolyte ionization or at least one in alcoholic solution; Wherein, electrolyte also comprises the silicon dioxide that makes electrolyte gel.Like this, make electrolyte in gel state, battery can not produce leakage, thereby makes battery not only safe and reliable and have longer life, and very convenient carrying and storage.
After electrolyte gel, form silica particle.The particle diameter of micelle is different, and its specific area differs greatly.And the particle diameter of micelle depends primarily on preparation technology.
As shown in table 1, particle diameter is less, and the specific area of micelle is larger.Accordingly, the specific area of micelle is larger, and the surface of micelle can be just larger, and the reactivity of micelle is corresponding increase also.
Table 1
Particle diameter D (nm) Specific area (m 2/g)
＜3 ＞1000
3～4 750～900
7～8 350～400
11～13 190～270
16～20 130～170
When particle diameter hour, between micelle, be easy to the formation chemical bond that reacts.When micelle near time, between micelle, by silanol condensation, form silicon oxygen bond, the skeleton that gel mainly relies on silicon oxygen bond to build is supporting.In skeleton, can wrap up water or alcohol, thereby form gel.And the process that forms silicon oxygen bond is irreversible, make the skeleton that relies on silicon oxygen bond to form be difficult to be broken.Therefore, hour, its gelation rate is very fast for particle diameter, forms that gel is fine and close, hard, intensity is large.
And along with the increase of particle diameter, the surface activity of micelle reduces, micelle centre-to-centre spacing also strengthens gradually, and the chance that forms silicon oxygen bond that reacts to each other between particle reduces.A small amount of less micelle is coupled to after larger micelle, and in system, the aggregation rate of particle will reduce.Now, between micelle, can not form three-dimensional framework by forming silicon oxygen bond.
Silica particle surface has a lot of hydroxyls, now can pass through Hydrogenbond, with hydrogen bond form, forms three-dimensional framework.And hydrogen bond is intermolecular a kind of weak binding, easily destroyed.Therefore.The skeleton forming by hydrogen bond is easily broken, and needs only shearing force a little, and skeleton is just destroyed, and the water or the alcohol that are wrapped in skeleton just can discharge.Once but remove shearing force, and skeleton structure is set up again, and water or alcohol are wrapped again.In sum, the formation of skeleton and to break be reversible completely, gels-soft is and flexible, and thixotropy is better.
Preferably, the particle diameter of micelle is not more than 20nm.If particle size analysis is excessive, fine although gel is cut rare property, three-dimensional framework forms very slow, be not enough to good gelation, and hydration phenomena is also comparatively serious.

In electrolyte, the weight accounting of silicon dioxide in electrolyte is 0.2%～20%, thereby guarantees that electrolyte has good gelling performance.
Preferably, the weight accounting of silicon dioxide in electrolyte is 0.2～0.5%, further improved the gelling performance of electrolyte.
Preferably, the weight accounting of silicon dioxide in electrolyte is 1.0～20%, further improved the gelling performance of electrolyte.
Preferably, the weight accounting of silicon dioxide in electrolyte is 1.0～3.2%.
Preferably, the weight accounting of silicon dioxide in electrolyte is 4.0～4.5%.

In addition, silicon dioxide also can be prepared by silicate.In the world, the reserves of silicate are more, easily obtain, and cost compare is low.
Silicate can be selected from a kind of in sodium metasilicate, alumina silicate, potassium silicate, calcium silicates, silicic acid phosphorus, Magnesiumaluminumsilicate, lithium magnesium silicate.Certainly, also can be selected from and take montmorillonite, the smectite that alumina silicate is main component.
In addition, cheap because of water glass solution, the water glass solution that contains sodium metasilicate of often take is prepared silicon dioxide as raw material.Simple process flow is: concentrated → ultrafiltration that water glass solution → acid neutralization → anion-cation exchange resin is processed (stirring) → reduction vaporization.After ultrafiltration, the purity of silicon dioxide is higher, has reduced the impact of other metal impurities ion pair battery performance, and has improved the gelling performance of electrolyte.
