Garaafka la balaariyay waxa uu ka samaysan yahay garaafyada flake ee dabiiciga ah, kaas oo dhaxla sifooyinka tayada sare leh ee jidheed iyo kiimikaad ee graphite-ka, waxa kale oo uu leeyahay astaamo badan iyo xaalado jidheed oo aanu lahayn graphite flake. Garaafyada la balaariyay, oo leh conductivity heer sare ah, ayaa si weyn loogu isticmaalaa soo saarista walxaha korantada waana walxo unug shidaal oo heersare ah. Tifaftiraha soo socda ee Furuite Graphite ayaa sharxi doona sababta graphite la balaariyay loogu isticmaali karo in lagu sameeyo baytariyada:
Sanadihii la soo dhaafay, cilmi baarista garaafyada la balaariyay sida xogta unugyada shidaalka ayaa noqotay mawduuc kulul adduunka oo dhan. Sida xogta unugyada shidaalka, waxay isticmaashaa sifada ah in tamarta bilaashka ah ee falcelinta interlayer ee garaafyada la balaariyay loo beddelo tamar koronto, badiyaa iyadoo la ballaariyay graphite sida cathode iyo lithium ama zinc sida anode. Intaa waxaa dheer, ku darida graphite balaariyay batteriga Zn-Mn waxay kor u qaadi kartaa conductivity electrode iyo electrolyte, waxay bixiyaan sifooyin qaabaynta aad u fiican, la joojiyo kala diridda iyo qallafsanaanta anode, iyo kordhiyo nolosha adeegga batteriga.
Walxaha kaarboon waxaa inta badan loo isticmaalaa sida walxo korantada ah sababtoo ah dhaqdhaqaaqooda sare. Sida nooc cusub oo kaarboon nanometer ah, garaafyada la balaariyay ayaa leh astaamaha porosity, aag gaar ah oo dusha sare ah iyo dhaqdhaqaaqa dusha sare. Ma aha oo kaliya in ay leedahay conductivity aad u fiican iyo adsorption, laakiin sidoo kale waxay leedahay xasilloonida kiimikada aad u fiican, sidaas darteed waxaa si ballaaran loo isticmaalaa in xogta electrode.
Furuite Graphite waxay inta badan ku hawlan tahay alaabada garaafyada dhamaadka-dhamaadka sare leh, oo leh noocyo kala duwan oo tilmaamo garaafka la ballaariyay. Tilmaamo gaar ah ayaa loo habeyn karaa iyadoo loo eegayo shuruudaha macaamiisha, muunado ayaa lagu diri karaa boostada. Dhinacyada danaynaya waa lagu soo dhawaynayaa inay tashadaan.
