Garaafyada la balaariyay waxaa laga soo farsameeyaa garaafyada flake ee dabiiciga ah, kaas oo dhaxla tayada tayada sare leh ee jirka iyo kiimikaad ee graphite flake, sidoo kale waxa uu leeyahay astaamo badan iyo xaalado jireed oo aanu lahayn graphite flake. Garaafyada la balaariyay ayaa leh koronto heer sare ah waxaana si weyn loogu isticmaalaa soo saarista qalabka elektiroonigga ah, waana walxo unug shidaal oo aad u fiican. Tifaftiraha garaafiga Furuite ee soo socda ayaa falanqeyn doona sababta garaafiga la ballaariyay loogu isticmaali karo sameynta baytariyada:
Sanadihii la soo dhaafay, cilmi baaris ku saabsan graphite balaariyay sida walxaha unugyada shidaalka ayaa noqday mawduuc aad u kulul cilmi baarista caalamiga ah. Maaddada batari ahaan, waxay isticmaashaa sifooyinka tamarta bilaashka ah ee falcelinta interlayer-ka ee garaafka la ballaariyay si loogu beddelo tamarta korantada, badiyaa iyadoo la ballaariyay graphite sida cathode iyo lithium ama zinc sida anode. Intaa waxaa dheer, ku darida graphite balaariyay batari zinc-manganese kor u qaadi kartaa conductivity ee electrode iyo electrolyte ah, oo ay bixiyaan sifooyinka qaabaynta aad u fiican, la joojiyo kala diridda iyo qallafsanaan ee anode ah, iyo kordhiyo nolosha adeegga batteriga.
Walxaha kaarboon waxaa inta badan loo isticmaalaa sida walxaha korantada taasoo ay ugu wacan tahay korantada wanaagsan ee ay leeyihiin. Sida nooc cusub oo kaarboon nano-cabbir ah, graphite balaariyay ayaa leh sifooyinka dabacsan iyo dalool, aag gaar ah oo weyn iyo dhaqdhaqaaqa dusha sare. Ma aha oo kaliya in ay leedahay conductivity aad u fiican iyo adsorption, laakiin sidoo kale waxay leedahay xasilloonida kiimikada heer sare ah, sidaas darteed waxaa si ballaaran loo isticmaalaa in qalabka electrode.
Furuite Graphite waxay inta badan ku hawlan tahay alaabada garaafyada dhamaadka-sare. Waxaa jira noocyo badan oo kala duwan iyo qeexitaanno graphite balaariyay. Tilmaamaha gaarka ah waxaa loo habeyn karaa iyadoo loo eegayo shuruudaha macaamiisha. Tusaalooyinka waa la diri karaa Haddii aad xiisaynayso, fadlan nala soo xidhiidh.
