Description

Connect the tubular plastic storage battery

The utility model relates to a kind of storage battery, specifically a kind of tubular plastic storage battery that connects.

Having many uses of lead acid accumulator, but the corrosion resistance of pole plate never thoroughly solves.Chinese patent 95233119.5 discloses a kind of sealed lead-acid accumulator free from maintenance, this battery is a hermetically-sealed construction, the self-protection performance is good, has removed the trouble of normal maintenance from, is a kind of comparatively advanced storage battery, but its grid still adopts lead alloy material to make, and capacity is less, and the scope of application has certain limitation, and the charge and discharge characteristic of internal structure and battery has specific limit, often, cause end of life because of the grid corrosion causes active material to come off.

The purpose of this utility model provides a kind of in light weight, pollution-free, non-maintaining, stable performance entirely, long company's tubular plastic storage battery of life-span.

For achieving the above object, the technical solution of the utility model is: this connects the skeleton symbol plastic battery and comprises shell, cover plate, positive and negative terminals, plate railings of anode and cathode, the both positive and negative polarity active material, electrolyte, the both positive and negative polarity dividing plate, sump assemblies, bus-bar, terminal, the battery structure center is a sump assemblies, outwards be arranged in order from sump assemblies and severally connect the single lattice of cartridge type to several, the structure of single lattice is by anodal dividing plate, anode plate grid, positive active material, anodal dividing plate, electrolyte, the negative pole dividing plate, negative electrode grid, negative electrode active material, the negative pole dividing plate is arranged in order composition, positive and negative grid material is a compound conductive plastic, there is liquid sucking device in the both positive and negative polarity exit, liquid sucking device directly feeds sump assemblies, and safety valve is arranged at each single lattice top.

Aforesaid Plastic accumulator, key are thoroughly to change the material of plate railings of anode and cathode, adopt compound conductive plastic, not only weight saving, and overcome active material that the grid corrosion causes and come off and cause battery end of life.Grid has good corrosion resistance, can support active material to stick to securely on the grid grid, replaced traditional lead alloy material, can guarantee active material participation chemical reaction, make active material even in the pole plate distributed throughout, pole plate CURRENT DISTRIBUTION unanimity everywhere, thus it is stable to reach battery performance, long service life.

Aforesaid Plastic accumulator, its safety valve is the control internal pressure, in the normal use, the gas that inside battery produces is absorbed by the liquid sucking device in both positive and negative polarity exit respectively, automatic transport is to inner sump assemblies then, cause capacity to descend with the oxidation that prevents battery pole plates, lack of water, the pernicious gas in the battery can not outwards be discharged, battery is pollution-free.

Aforesaid Plastic accumulator uses the drum type brake positive/negative plate, the distribution of pole plate from inside to outside, diameter is ascending, bipolar ear connects, and shortens current flow path, reduces the internal resistance of cell, reduces the loss of voltage, increases battery capacity.

Aforesaid Plastic accumulator; use contains the extremely low electrolyte (matter) of acid; this electrolyte becomes pasty state; after adding battery; instantaneously promptly form gluey protective layer around the pole plate, can prevent that active material from coming off, the ambient temperature applicability is strong; can be under-40 ℃ of-70 ℃ of conditions operate as normal, the lifelong uncomfortable proportion of wiping away.

Aforesaid Plastic accumulator, profile is a cuboid, Dan Gewei connects cartridge type, changes the pole plate shape, but the multilayer arrangement, many link to each other; Be respectively charged into the different positive/negative plate of diameter, dividing plate in each, adopt tight fit, dividing plate is a pocket type, positive/negative plate is respectively charged in the bag, the active material of positive/negative plate is not come off and become flexible, thereby make active material long-term work on original position, and the battery short circuit phenomenon can not occur.

Aforesaid Plastic accumulator, anodal dividing plate are the terylene dividing plate.The negative pole dividing plate is a glass fibre absorption dividing plate, and under the condition of discharging and recharging, the anodal gas that produces is absorbed by negative pole and is combined to water again, makes inside battery not have gas and discharges.

Aforesaid Plastic accumulator, positive/negative plate diameter, area do not wait, and the positive/negative plate number equates, broken through negative plate for many years and manyed the routine of a slice than positive plate, and CURRENT DISTRIBUTION is even.

Aforesaid Plastic accumulator adopts hermetically sealed tight fit, and is complete non-maintaining pollution-free.

Aforesaid Plastic accumulator, plate railings of anode and cathode, terminal all adopt the composite plastic injection mo(u)lding, manufacturability is strong, and applicable different capabilities, difform pole plate grid adopt bonding welding manner, each one is connected firmly, conductivity is strong, is suitable for big electric current charge and discharge, makes the specific energy of battery improve 30%, weight saving 32%, the life-span has prolonged more than 1.5 times.

Aforesaid Plastic accumulator can replace traditional various model lead acid accumulators, and capacity and volume can be produced according to the instructions for use design, and shape can be for connecting cartridge type or the exposed cartridge type that connects in the cuboid.

In sum, the utility model has the advantages that: in light weight, energy is high, the life-span is long, the self-protection performance is good, non-maintaining, stable performance entirely, pollution-free, purposes is wide.
