Xa igraphite iphathwa ngokwekhemikhali, ukusabela kweekhemikhali kuqhutywa ngaxeshanye emphethweni wegraphite eyandisiweyo naphakathi kwendawo. Ukuba i-graphite ayihlambulukanga kwaye iqulethe ukungcola, iziphene ze-lattice kunye ne-dislocations ziya kubonakala, okubangelwa ukwandiswa kommandla wecala kunye nokwandiswa kweendawo ezisebenzayo, eziza kukhawuleza ukuphendulwa komda. Nangona oku kunenzuzo ekubunjweni kwee-edge compounds, kuya kuchaphazela ukubunjwa kwe-graphite intercalation compounds eyandisiweyo. Kwaye i-lattice elayitiweyo itshatyalalisiwe, eyenza i-lattice iphazamiseke kwaye ingahambi kakuhle, ukwenzela ukuba isantya kunye nobunzulu bokusasazwa kweekhemikhali ukuya kwi-interlayer kunye nesizukulwana se-deep intercalation compounds sithintelwe kwaye silinganiselwe, esichaphazela ngakumbi ukuphuculwa kwedigri yokwandisa. Ngoko ke, kuyimfuneko ukuba umxholo wokungcola kwegraphite kufuneka ube phakathi koluhlu oluchaziweyo, ngokukodwa ukungcola kwegranular akufanele kube khona, ngaphandle koko izikali zegraphite ziya kunqunyulwa ngexesha lenkqubo yokucinezela, eya kunciphisa umgangatho wezinto ezibunjiweyo. Lo mhleli ulandelayo we-Furuite graphite wazisa ukuba ukucoceka kwezinto zegraphite ekrwada kuchaphazela iipropathi zegraphite eyandisiweyo:
Ubungakanani bamasuntswana egraphite bukwanempembelelo enkulu ekuvelisweni kwegraphite eyandisiweyo. Ubungakanani bamasuntswana bukhulu, indawo ethile yomphezulu incinci, kwaye indawo ebandakanyekayo kwimpendulo yekhemikhali incinci ngokuhambelanayo. Ngokuchasene noko, ukuba i-particle incinci, indawo yayo ethile iphezulu, kwaye indawo yokuthatha inxaxheba kwi-chemical reactions inkulu. Ukusuka kuhlalutyo lobunzima bezinto zekhemikhali ezihlaselayo, akunakuphepheka ukuba amasuntswana amakhulu aya kwenza isikali segraphite sibe ngqindilili, kwaye izikhewu phakathi kwamaleko ziya kuba nzulu, ngoko ke kunzima ukuba imichiza ingene kwinqanaba ngalinye, kwaye ngakumbi. kunzima ukusasazeka kwizithuba phakathi kwamaleko ukuze kubangele iileya ezinzulu. Oku kunempembelelo enkulu kwiqondo lokwandiswa kwegraphite eyandisiweyo. Ukuba i-graphite particles ihle kakhulu, indawo ethile yendawo iya kuba nkulu kakhulu, kwaye ukuphendulwa komda kuya kuba yinto eveleleyo, engabandakanyi ukubunjwa kwe-intercalation compounds. Ngoko ke, iinqununu zegraphite akufanele zibe zikhulu kakhulu okanye zincinci.
Kwimeko-bume efanayo, kubudlelwane phakathi koxinaniso oluxekethileyo kunye nobungakanani besuntswana legraphite eyandisiweyo eyenziwe ngegraphite enobungakanani bamasuntswana ahlukeneyo, okukhona kuncinci ukuxinana okukhululekileyo, ngcono isiphumo segraphite eyandisiweyo. Nangona kunjalo, kwimveliso yangempela, kuboniswa ukuba uluhlu lwesayizi ye-particle ye-graphite esetyenzisiweyo ikhethwa ngokukhethekileyo ukusuka kwi--30 mesh ukuya kwi-100 mesh, eyona mpembelelo ifanelekileyo.
Impembelelo ye-graphite ubungakanani besuntswana nayo ibonakaliswe kwinto yokuba ubungakanani besuntswana lokwakheka kwezithako akufuneki lube banzi kakhulu, oko kukuthi, umahluko phakathi kwesuntswana elikhulu kunye nelona lincinci lincinci akufanele libe likhulu kakhulu, kwaye isiphumo sokucubungula siya kuba ngcono ukuba ubungakanani bokwakheka kwamasuntswana bufana. Iimveliso zegraphite zeFuruite zonke zenziwe ngegraphite yendalo, kwaye umgangatho ufuneka ngokungqongqo kwinkqubo yokuvelisa. Iimveliso zegraphite ezicutshungulwayo kwaye zaveliswa zithandwa ngabathengi abatsha nabadala iminyaka emininzi, kwaye usoloko wamkelekile ukuba udibane kwaye uthenge!
