鉛酸蓄電池先進(jìn)板柵設(shè)計(jì)案例

 

超出板柵傳統(tǒng)的設(shè)計(jì),采用新工藝、新技術(shù)、新材料、新設(shè)計(jì)理念開發(fā)如下先進(jìn)的板柵設(shè)計(jì)。

( 1 )平面式管狀電極
日本湯淺(Yuasa )承擔(dān)的先進(jìn)鉛酸蓄電池聯(lián)合會(huì)(ALABC )項(xiàng)目,平面式管狀電極已應(yīng)用于電動(dòng)汽車(EV )與混合動(dòng)力電動(dòng)汽車(HEV ) 以及其他循環(huán)使用的場(chǎng)合。其板柵是用鑄造或擠壓生產(chǎn)的,采用Pb-Ca -Sn 合金。

( 2 )薄片電極
薄片正極比普通的鑄造板柵或拉網(wǎng)板柵的正極有更均勻的放電性能.通過這種電極表面的充/放電電流是均勻的,另外腐蝕速率也降低了。因?yàn)榘鍠庞袠O高的表面積,因此比普通板柵有低得多的腐蝕電流密度(A/cm2 )。
這類電極是由美國Wirtz 公司開發(fā)的conroll 極板,板柵厚度<1 mm , 質(zhì)盤很輕。這種材料在美國EastPenn 公司承擔(dān)的先進(jìn)鉛酸蓄電池聯(lián)合會(huì)( ALABC )項(xiàng)目中應(yīng)用。
( 3
)箔式卷狀電極
真正薄如紙的電極由美國Bolder 公司開發(fā),稱為“TMF ”技術(shù)( t hin metal film )箔式電極,具有極高比功率與優(yōu)異的可充性。這種電極的板柵僅為0 .05 -0.08mm ,與活性物質(zhì)層的厚度相近,卷成電極。電池正極在一端,負(fù)極在另一端,和堿錳電池類似。高倍率放電性能優(yōu)異,已用于電動(dòng)工具、汽車起動(dòng)、混合動(dòng)力等領(lǐng)域。
( 4
)螺旋卷狀電極
美國Exide 公司首次推出采用螺旋卷狀電極的圓柱形電池,作為起動(dòng)用的新型閥控密封蓄電池.活性物質(zhì)用機(jī)械擠壓到薄極板上,采用新的連續(xù)制造技術(shù)。

Outrun a plank grid traditional design, adopt the plank grid that the new craft, new technique, new material, new design principle develops the following forerunner design.
(1)the flat surface type take care of form electrode
The advanced lead that Japanese soup is shallow(Yuasa) to undertake sour storage battery unite meeting(ALABC) item, the flat surface type takes care of form electrode already applied at the dynamoelectric car(EV) with mixture power dynamoelectric car(HEV) and other circulation use of situation.Its plank grid is use to cast or squeeze production, adopt Pb-Ca-Sn metal alloy.
(2)thin slice electrode
Thin slice cathode than common foundry plank grid or pull the cathode of net plank grid to have more evenly turn on electricity function.pass this kind of electrode surface of Chong/turn on electricity electric current is even, decay another velocity to also lower.The plank grid has the highest surface to accumulate, therefore compare common plank grid is low many corrosion electric current densities.(A|cm 2)
This electrode is the conroll pole that is developed by the United States' Wirtz company plank, plank grid thickness<1 mm, the quality dish is light.This kind of material undertakes in the EastPenn company of the United States of advanced lead the sour storage battery associately apply in the meeting( ALABC) item.
(3)screen type book-like in shape electrode
Is truely thin is developed by the United States' Bolder company, be called "TMF" the technique( t hin metal film) screen type electrode, have such as the electrode of paper very Gao Bi power with excellently can Chong.The plank grid of this kind of electrode is only 0.05-0.08 mmses, similar to the thickness of live material layer, book becomes electrode.Battery cathode at on carrying, anode at another on carrying, with alkali manganese the battery is similar.Gao magnification turns on electricity function excellent, have already used for a dynamoelectric tool, car to start, mixture power etc. realm.
(4)spiral book-like in shape electrode
The Exide company in the United States releases the cylinder form of adopting the spiral book-like in shape electrode battery for the very first time, conduct and actions start the new valve using to control to seal completely storage battery.the live material is squeezed with the machine thin very in the plank, adoption lately of continuous manufacturing technique.
