Fig. 2 is traditional AGM storage battery exemplary plot;
The concrete battery example figure of one that Fig. 3 provides for the embodiment of the present invention;
A kind of cell manufacturing method flow chart that Fig. 4 provides for the embodiment of the present invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
The invention provides a kind of battery, as shown in Figure 1, this battery housing, positive plate, negative pole version, dividing plate and electrolyte, described positive plate, negative plate, dividing plate and electrolyte are placed in described housing, described dividing plate is between described positive plate and described negative plate, for adsorbing described electrolyte, preventing short circuit between described positive plate and described negative plate, described dividing plate comprises SiO 2colloid.What deserves to be explained is, can be different according to different battery types separator materials and bath composition, dividing plate such as in AGM storage battery is glass fiber material, electrolyte is sulfuric acid electrolyte, and this programme does not limit the material of dividing plate and the composition of electrolyte.
In the middle of concrete implementation procedure, comprising herein can be presented as various ways, optionally comprises mode as one, can be SiO 2colloid covers described baffle surface, can also be SiO 2colloid is infused in described dividing plate.No matter in which type of mode comprise, the dividing plate in the embodiment of the present invention comprises SiO 2colloid, for making described SiO 2colloid is combined with described electrolyte, forms SiO with the electrolyte of fixing described inside battery 2gel.Thus avoid electrolyte layering under gravity, greatly reduce the positive plate of layering electrolyte to inside battery and the corrosion of negative plate, extend battery life.
What deserves to be explained is, in order to make the optimized performance of battery, the SiO in the embodiment of the present invention 2colloid can be evenly divide in baffle surface, or be evenly distributed in dividing plate.
In order to the battery concrete form of the clearer explanation embodiment of the present invention, be described for AGM storage battery below.
Be illustrated in figure 2 traditional AGM storage battery, be made up of housing, positive plate, negative plate and electrolyte and dividing plate, described positive plate, negative plate, dividing plate and electrolyte are placed in described housing, wherein electrolyte is sulfuric acid electrolyte, separator material is glass fibre, this glass fibre separator is placed between positive plate and negative plate, for adsorbing described electrolyte, preventing short circuit between described positive plate and described negative plate.Because Action of Gravity Field often makes electrolyte present lamination in conventional batteries, as shown in Figure 2 in this AGM storage battery because Action of Gravity Field makes the density bottom sulfuric acid electrolyte much larger than the density at top, such battery is once work together, namely in charge and discharge process, the high density electrolyte that after this layering, bottom exists exacerbates the positive plate of inside battery and the corrosion of negative plate, thus battery is shortened greatly.
In the battery that the embodiment of the present invention provides, because the dividing plate between positive/negative plate includes SiO 2colloid, as shown in Figure 3, this SiO 2colloid uniform fold, in baffle surface, also can be evenly be added on inside dividing plate or in other manners by this SiO in other examples 2colloid is evenly included on dividing plate, thus makes this SiO 2the sulfuric acid electrolyte that colloid and note fill between dividing plate and positive/negative plate carries out chemical action, and the sulfuric acid electrolyte finally fixing this AGM inside battery forms SiO 2gel.This SiO 2gel due in colloidal state and avoid electrolyte layering under gravity, also just greatly reduces the corrosion of positive plate to inside battery and negative plate, extends battery life.
It should be noted that, the embodiment of the present invention is described for AGM storage battery, but the present invention is not limited to AGM storage battery, can be any battery comprising dividing plate and electrolyte, and specific features is described above, repeats no more herein.
