Ma graphite owonjezera ndi mtundu wa zinthu zotayirira komanso zowoneka ngati nyongolotsi zomwe zimapezeka kuchokera ku flake graphite yachilengedwe kudzera pakuphatikizana, kuchapa, kuyanika ndi kukulitsa kutentha kwambiri. Ndi chotayirira komanso porous granular latsopano carbon zakuthupi. Chifukwa cha kuyika kwa intercalation agent, thupi la graphite liri ndi makhalidwe a kukana kutentha ndi mphamvu zamagetsi, ndipo amagwiritsidwa ntchito kwambiri posindikiza, kuteteza chilengedwe, zoletsa moto ndi zipangizo zoyaka moto ndi zina. Mkonzi wotsatira wa Furuite Graphite amayambitsa mapangidwe ndi mawonekedwe a pamwamba pa graphite yowonjezereka:
M'zaka zaposachedwa, anthu amayang'anitsitsa kwambiri kuwonongeka kwa chilengedwe, ndipo mankhwala a graphite okonzedwa ndi njira ya electrochemical ali ndi ubwino wa kuwonongeka kwa chilengedwe, kutsika kwa sulfure ndi mtengo wotsika. Ngati electrolyte siiipitsidwa, ikhoza kugwiritsidwanso ntchito, kotero yakopa chidwi kwambiri. The osakaniza njira ya asidi phosphoric ndi asidi sulfuric ntchito monga electrolyte kuchepetsa ndende ya asidi, ndi Kuwonjezera asidi phosphoric komanso anawonjezera makutidwe ndi okosijeni kukana kukodzedwa graphite. Ma graphite okonzeka okulitsidwa amakhala ndi mphamvu yabwino yoletsa moto akagwiritsidwa ntchito ngati kutchinjiriza kwamafuta ndi zida zosayaka moto.
Micro-morphology ya flake graphite, graphite yowonjezera ndi graphite yowonjezera idapezeka ndikuwunikidwa ndi SEM. Pa kutentha, ndi interlayer mankhwala mu graphite expandable adzakhala kuwola kupanga zinthu mpweya, ndi kukula mpweya adzapanga amphamvu galimoto mphamvu kuwonjezera graphite pamodzi malangizo a C olamulira kupanga kukodzedwa graphite mu mawonekedwe mphutsi. Choncho, chifukwa cha kufalikira, malo enieni a graphite yowonjezereka akuwonjezeka, pali ma pores ambiri ngati chiwalo pakati pa lamellae, mawonekedwe a lamellar amakhalabe, mphamvu ya van der Waals pakati pa zigawozo ikuwonongedwa, zosakaniza zosakanikirana zimakhala bwino. kukulitsidwa, ndipo kusiyana pakati pa zigawo za graphite kumawonjezeka.
