Storage batterycomprising a positive electrodeplate, a negativeplate,a separator,an electrolyte,the housing,the battery cover,polepilesand other components.
1.Plates
Isthe core ofthe batteryplates,the batterycharge and dischargeprocess,chemical energyandelectrical energyconversionis througha positive,electrochemical reactionon the negative plateactive material and thesulfuric acid electrolyteto achieve.
Subpositivebattery plates,negative plates,andby the gateframeconsisting ofactive substance.Active material-filledcastinlead-antimony alloygridshelves,the active substancein thepositive plateisbrownlead dioxide(Pb02),the negative plateactive materialisgrayspongylead(Pb).Currently, domesticbattery platethickness1.6 ~ 2.4mm.
In order toincrease the capacity ofthe battery,usuallymulti-piecepositive and negative platesare connected in parallel,with ahorizontalplate welding.Wheninstalled,the positive and negativeplatesfittedto each other,with the interposition ofa separator,consisting ofpositive,negative plate.At the same time,cross-boardcasta verypiles,in order to connectthe varioussingle-cell battery.
Ineach of thesingle-cell battery, the number ofnegative platespositive platemorethanone.For example, DongfengAutomobileEQl0906 usedaQ-105type battery,everysingle cellCKSplateforseven,the negative plateforeight.This is because thepositive electrode platecarryingthe negative electrode plateswhenthe electrochemicalreaction isstronglyratio,and thepositive electrodeactive materialrelatively looseplate,a positive electrodeplatein order to preventa dischargecaused by unevenplateleaving theactive material sheddingdoming,sothe positive electrodeatthe time of manufacturebetween thenegative electrodeplate in theplate.
2.Clapboard
To avoidthe positive and negativeplatesin contactwith each otherwhilethe secondcause a short circuit,positive and negative platesseparated byan insulatingspacerasked.The separatorhas a porous,in order to facilitatepenetration ofthe electrolyte,reducing thebattery internal resistance.In addition, the chemicalstabilityis better, with acidand oxidation resistance.
Conventionalseparatormaterials arewood, porousrubber,microcellular plastics(polyvinyl chloride, phenolicresin),glass fiber,the separatorthickness of about1mm.
3.Electrolyte

The density ofthe electrolyteis usually1.23 ~ 1.30∥cm3,should be based onthe use ofdensityareas, climatic conditions andthe manufacturer'srequirements may be
