Kapangidwe ndi mawonekedwe a pamwamba pa graphite yokulirapo

Graphite yokulirapo ndi mtundu wa chinthu chofanana ndi nyongolotsi chotayirira komanso chopanda pobowola chomwe chimapezeka kuchokera ku graphite yachilengedwe yopyapyala kudzera mu intercalation, kutsuka, kuumitsa ndi kukulitsa kutentha kwambiri. Ndi chinthu chatsopano cha kaboni chotayirira komanso chopanda pobowola. Chifukwa cha kuyika kwa intercalation agent, thupi la graphite lili ndi makhalidwe a kukana kutentha ndi kuyendetsa magetsi, ndipo limagwiritsidwa ntchito kwambiri potseka, kuteteza chilengedwe, zinthu zoletsa moto ndi zoteteza moto ndi zina. Mkonzi wotsatira wa Furuite Graphite akuwonetsa kapangidwe ndi mawonekedwe a pamwamba pa graphite yokulirapo:

M'zaka zaposachedwapa, anthu amaika chidwi kwambiri pa kuipitsidwa kwa chilengedwe, ndipo zinthu za graphite zomwe zimapangidwa pogwiritsa ntchito njira ya electrochemical zili ndi ubwino wochepa wa kuipitsidwa kwa chilengedwe, kuchuluka kwa sulfure kochepa komanso mtengo wotsika. Ngati electrolyte sinaipitsidwe, ikhoza kugwiritsidwanso ntchito, kotero yakopa chidwi chachikulu. Njira yosakanikirana ya phosphoric acid ndi sulfuric acid idagwiritsidwa ntchito ngati electrolyte kuti ichepetse kuchuluka kwa asidi, ndipo kuwonjezera kwa phosphoric acid kunawonjezeranso kukana kwa okosijeni kwa graphite yokulirapo. Graphite yokulirapo yokonzedwayo imakhala ndi mphamvu yabwino yoletsa moto ikagwiritsidwa ntchito ngati chotenthetsera kutentha komanso zinthu zosapsa moto.

Kapangidwe kakang'ono ka graphite yopyapyala, graphite yotambasuka ndi graphite yotambasuka kanapezeka ndi kufufuzidwa ndi SEM. Pa kutentha kwakukulu, ma compounds ophatikizana mu graphite yotambasuka amawola kuti apange zinthu za gasi, ndipo kukulitsa kwa gasi kudzapanga mphamvu yoyendetsa yamphamvu kuti ikule graphite motsatira C axis kuti ipange graphite yotambasuka ngati nyongolotsi. Chifukwa chake, chifukwa cha kukulitsa, malo enieni a graphite yotambasuka amawonjezeka, pali ma pores ambiri ofanana ndi ziwalo pakati pa lamellae, kapangidwe ka lamellar kamatsala, mphamvu ya van der Waals pakati pa ma layer imawonongeka, ma compounds ophatikizana amawonjezeka kwathunthu, ndipo mtunda pakati pa ma layer a graphite umawonjezeka.
