Abstract
The utility model discloses a wedge-shaped polar board of which the upper part is thick and the lower part is thin. The utility model adopts the wedge-shaped polar board. After assembled, the looseness and tightness of the upper part and the lower part of the wedge-shaped polar board are consistent and even. The liquid absorbing quantity of the upper and the lower parts is even, the depth of discharge is basically equal and the electricity conducting ability is also basically equal. Both the upper part and the lower part are easily charged. The utility model realizes the balance discharge and the balance charge of the upper part and the lower part and enhances high current discharging and quickly charging ability, which causes the performance of a battery to be kept well but can not result in the quick deterioration of the polar board.
Description
[technical field]
The utility model relates to the positive/negative plate of storage battery, the positive/negative plate of particularly dark circulation usefulness and lean solution formula storage battery.
[background technology]
Electric motor car is a kind of important vehicles, brings great convenience for people's life, and storage battery is can not learn few pith in the electric motor car, and present battery manufacturer merchant is also few, and these manufacturers adopt conventional conventional batteries.The charge acceptance of battery is low, the charging interval long, the life-span is short, and these fatal defectives have seriously hindered the development of electric motor car.For overcoming many defectives of above-mentioned battery, applicant has been researched and developed a kind of electrode plate structure lean solution formula battery different with traditional storage battery, this Pollution of Battery has brought new life for the development of electric motor car industry than conventional batteries is little a lot, charge acceptance is strong, the charging interval is short, the long service life of battery.
Mainly solved problem: because the shell of storage battery is trapezoidal, certain pattern draft (wide at the top and narrow at the bottom) is arranged, and at present the positive/negative plate that adopted of conventional accumulators all is that thickness is uniform up and down, so will occur after the assembling that Panasonic is tight, degree of tightness is inhomogeneous; Be valve-regulated sealed lead-acid battery (being lean solution formula battery) because of what adopt again, so just exist the electrolyte saturation on top to be lower than the electrolyte saturation of bottom, discharge the time just causes the bottom discharge capacity to be higher than top discharge capacity (depth of discharge) like this, and during charging because bottom electrolyte has consumed, the lead sulfate content that adds in the top crown is higher, resistance strengthens, cause charging to be difficult to carry out, and top is few owing to electrolyte, discharge capacity is few, conductive capability is stronger, is charged easily in top.So just formed the top difficult discharge of easily charging, and the energy imbalance of the difficult charging of bottom Yi Fangdian, thereby caused top to be overcharged and charging is owed in the bottom, caused that battery performance decays fast, even cause the quick deterioration of pole plate to be scrapped.
So, how to adopt effective method to realize that discharging and recharging of top and the bottom is in a basic balance, thereby the performance that improves battery becomes the important topic of electromobile battery industry research.
[summary of the invention]
The purpose of this utility model solves the problems of the prior art exactly, proposes a kind of chock shape pole plate, makes the top and the bottom of lean solution formula battery that uniform assembling elasticity be arranged, and charging and discharge can balances.
For achieving the above object, the utility model provides a kind of chock shape pole plate, the thick bottom thin in pole plate top.
Further, comprise silicon dioxide and sodium carboxymethylcellulose in the active material of pole plate.Help improving pole plate and inhale the acid amount and improve the ability that keeps electrolyte, make pole plate inhale acid evenly, and the protection pole plate, charge acceptance improved.
The beneficial effects of the utility model: the utility model adopts chock shape pole plate, and the assembling back is degree of tightness unanimity, very even up and down; The depth of discharge of top and the bottom is suitable substantially, conductive capability is also suitable substantially, the upper and lower is all than being easier to charging, the balance discharge and the equilibrium charging of upper and lower have been realized, heavy-current discharge and quick charge capability have been improved, make battery performance can be good at keeping, can not cause the quick deterioration of pole plate.
Feature of the present utility model and advantage will be elaborated in conjunction with the accompanying drawings by embodiment.
[description of drawings]
Fig. 1 represents the structural representation of the utility model chock shape pole plate.
[embodiment]
Embodiment one:
Be illustrated in figure 1 as the structural representation of the utility model chock shape pole plate; Pole plate is made chock shape, rather than make the shape that is of uniform thickness up and down as common pole plate, in the present embodiment pole plate is made the thick bottom thin in top, because the shell of storage battery also is trapezoidal, wide bottom, top is narrow, certain gradient is arranged, so such pole plate just just in time is complementary with the shell of storage battery, it is just all very tight up and down that the back is installed, the elasticity of upper and lower is even, inhales acid also relatively evenly.Like this, the charging of upper and lower and discharge are just in a basic balance.
Pole plate is the collector of conduction, is made by the various active material.Common opening battery grid is generally cast with lead-antimony alloy, the maintenance free cell grid is generally with low antimony alloy or lead-calcium alloy casting, and the designed seal valve control lead acid accumulator plate grid of the utility model is generally cast with lead-calcium multielement alloy, and the utility model also adds silicon dioxide (SiO in active material
2) and sodium carboxymethylcellulose (CMC) composition, make colloid polar plate, adopt the silicon dioxide (SiO of nanoscale fineness again
2) and organic polymer salt used as stabilizers, add the resistance that surfactant and conducting objects reduce colloid, prevent colloid aquation and layering.In the dividing plate of large aperture, add silicon dioxide (SiO
2) and sodium carboxymethylcellulose (CMC), both reduced clapboard aperture, prevent short circuit, the even content of colloid improves the hold facility to electrolyte again.Earlier determine that according to battery types the plumbous model of alloy puts into plumbous stove heat fused during making, plumbous liquid be cast in the metal die (metal die of chock shape) after reaching technological requirement that cooling back depanning is piled up through finishing; Grid after the finishing can change active matter full-filling operation over to through after certain timeliness, and active matter in the full-filling through operation such as filter acid, curing, dry, change into, is made positive/negative plate.
This product detects through national accumulator quality supervision and inspection center, and performance index meet or exceed the GB/T18332.1-2001 standard, and user's result of use is good, has favorable economic benefit and social benefit.
Claims (2)
1. a chock shape pole plate is characterized in that: the thick bottom thin in pole plate top.
