The positive and the negative plates are alternated with positive and negative and are provided with mutual embedment. A separator 5(separator network) with fictitious graticule structure and powdery carrier matter of electrolyte are arranged between the positive plate and the negative plate. The utility model has the advantages of small internal resistance, large energy storing and strong charge and discharge abilities.

Description

Colloid storage battery

Technical field

The utility model relates to a kind of storage battery that uses colloidal electrolyte, is specifically related to a kind of colloid storage battery internal structure.

Prior art

Storage battery commonly used at present is the plumbic acid liquid accumulator.Fig. 1 is common liq accumulator structure figure.Fig. 2 is a common liq storage battery outside drawing.Referring to Fig. 1 and Fig. 2, this storage battery is made up of battery case 107, battery cover 101, negative plate 103, positive plate 106, dividing plate 104 and liquid electrolyte, this storage battery is formed anodal group 105, is formed negative pole group 102 by the multi-disc negative plate by the multi-disc positive plate, and anodal group is electrically connected with positive pile 108, the negative pole group is electrically connected with negative pile 109.The drawback that this storage battery exists is that drivers are well-known, as: the electrolyte that positive and negative pile is very easily spilt corrodes and regularly additional electrolyte; All multifactor the coming off too early of pole plate, damage and pollution on the environments thereof of causing such as the washing away of liquid electrolytic confrontation pole plate, large current charge (discharge), circumstance of temperature difference in the use.In order to overcome above-mentioned defective, Chinese patent ZL92104882.3 discloses a kind of colloid storage battery and manufacture method thereof, and this patent replaces traditional liquid electrolyte with the pasty colloid electrolyte.Solved the problem that traditional electrolyte spills and the active material of liquid electrolytic confrontation pole plate and washed away problem, still, the charge acceptance of this battery, large current discharging capability, reserve capabillity are not ideal enough.Then be a kind of novel colloidal storage battery patent application of 01259212.9 in calendar year 2001 inventor's number of filing an application on September 3, this storage battery has solved the problem of charge acceptance, large current discharging capability and the capacity reserve ability of aforementioned storage battery existence.But, in the defective that exists limitation of the technology aspect the production and sales: after this colloid storage battery assembling finishes there is certain shelf life, exceeds its time limit then can to cause damage and waste, and the limitation of the scope of application.Therefore need to propose a kind of novel colloid storage battery.

Summary of the invention

The purpose of this utility model is to solve the problems of the prior art, proposes a kind of simple in structurely, fills long colloid storage battery of powdery carrier mass, shelf life.

For achieving the above object, the utility model provides a kind of colloid storage battery, by battery case, negative plate, positive plate, multi-disc positive plate form anodal group, the multi-disc negative plate is formed the negative pole group, described positive and negative pole plate is alternate positive and negative, mutual chimeric installation, spacer between described positive plate and the negative plate is a network structure, and its aperture is not more than the diameter of active material particulate on the described pole plate.

Above-mentioned colloid storage battery, the little plastic cement particle that described negative plate surface injection moulding is evenly distributed, its diameter is between 1.0mm～2.0mm.

Described dividing plate net is made up of the support frame and the dividing plate net of rectangle.The support frame interface is a rhombus.

The utility model compared with prior art has following advantage:

(1), use and to have a large amount of microcellular structure spacers as dividing plate, be suitable for carrying very strong moisture absorption performance flour, can be used as the carrier of electrolyte; The variation of internal storage battery structure makes storage battery dry powder substance to fill, and adds electrolyte during use again, prolongs the storage time.

(2), the difference of the visual positive and negative pole plate active material of spacer thread count and manufacturing technique requirent are different and change.

(3), this kind structure glue accumulator body, internal resistance is little, energy storage capacity is big, charging and discharging capabilities is strong, but dry type is deposited throughout the year.

Description of drawings

The invention will be further described below in conjunction with drawings and Examples.

Fig. 1 is common liq accumulator structure figure.

Fig. 2 is a common liq storage battery outside drawing.

Fig. 3 is the utility model structural representation (decomposing schematic representation).

Fig. 4 is two schematic diagrames of embodiment of the present utility model.

Embodiment

Referring to accompanying drawing 3, colloid storage battery of the present invention has battery case 6, battery cover 1, negative plate 4, positive plate 9, the multi-disc positive plate is formed anodal group 8, and be electrically connected with positive pile 7, the multi-disc negative plate is formed negative pole group 3, and is electrically connected with negative pile 2, and described positive and negative pole plate is alternate positive and negative, mutual chimeric installation is provided with the powder carrier material of the cancellated spacer of longitude and latitude (dividing plate net) 5 and electrolyte between described positive plate and the negative plate.The little plastic cement particle 13 that negative plate 4 surperficial injection mouldings are evenly distributed.The battery case that present embodiment adopted, negative plate, positive plate, battery cover are identical with common storage battery.The powder carrier material can of described electrolyte is between pole plate 4,9 and spacer 5.

In the environment of drying, the powder carrier material is mixed, be poured in the battery of the present utility model, make the storage battery sealing.When storage battery used, the electrolyte of preparing with special-purpose sulfuric acid of storage battery and pure water added in this storage battery, and the powder carrier material of this storage battery electrolyte inside can thixotroping be the colloidal material, forms gelated electrolyte.

Referring to Fig. 4, the cancellated spacer of longitude and latitude (dividing plate net) 5 that present embodiment uses, the netted density 12 of its longitude and latitude is not more than the mean particle dia of plate active material, and its dividing plate net can be by the support frame 11 of rectangle, closes with dividing plate net 12 thermoplastics to form.The design thickness of rectangular frame is about 1.5mm, and its cross section is a rhombus, reduces the contact area with pole plate thus, and this support frame adopts acidproof plastic injection-moulded.

The powder carrier material of electrolyte of the present invention can thixotroping be a colloidal electrolyte behind the perfusion electrolyte, can prevent the loss that comes off of active material on the pole plate.Once perfusion need not be added electrolyte all the life, looks the colloid situation and only need add pure water and get final product.
