Bayanin hanyar shiri na kayan haɗin gwiwar silicon-carbon don kayan anode na baturi na lithium
Hanyoyin gwaji don shirya abubuwan haɗin silicon-carbon
An gwada abun da ke tattare da sinadarin silicon-cb ta amfani da sarrafa plasma mafita (SPP). Sakamakon ya nuna cewa hanyar SPP ita ce hanya mai kyau don shirya baƙar fata na carbon tare da ƙarar pore mai girma, matsakaici da ƙananan tsarin pore. 0-22
“A cikin waɗannan karatun, ƙwayoyin kaushi kamar benzene kawai aka yi amfani da su don samar da CB. Koyaya, a cikin wannan binciken, mun bincika abun da ke tattare da abubuwan da aka haɗa ta hanyar shakatawa da nanoparticles na silicon a cikin kaushi na halitta kafin fitar da jini.
Anyi gwajin gwajin a dakin da zazzabi da matsi. Yin amfani da fensir na inji guda biyu azaman na’urorin lantarki don fitowar plasma, tun da yawancin wayoyi suna zubar da jini ko tururi, ana iya ɗauka cewa akwai ƙazanta a cikin abubuwan da aka haɗa.
Kowane lantarki yana rufe da bututun yumbu wanda aka saka a cikin filogi na silicone. Ana tattara nau’ikan na’urorin lantarki guda biyu a cikin bututun yumbu kuma an cika su da matosai na siliki, sannan ana sanya na’urorin a cikin baƙar fata mai diamita na 50 mm da tsayin mm 100 (Hoto na 1). Ana kiyaye nisa tsakanin na’urorin lantarki a 1 mm. The carbon precursor ne m xylene (reagent grade, sigma-aldrich), da kuma silicon nanopowder (uniform barbashi size = 100nm, AlfaAesar) an gauraye da xylene. Ana amfani da wutar lantarki ta bugun bugun jini don samar da fitarwa. Ana daidaita mitar wutar lantarki da faɗin bugun bugun zuwa 25khz da 0.5s bi da bi. Bayan fitarwa, ana tace ruwan da aka fitar ta hanyar cellophane don samun duk wani abu mai ƙarfi da ke cikin maganin. Sa’an nan kuma tace, a digiri 80 na celcius, yana da monotonous, yana barin wani abu mai laushi.
Xylene transpiration. Domin samun tabbatacce conductivity, an bi da shi a 700 ℃ na 1h a cikin wutar lantarki tanderu a karkashin N2 yanayi. Domin gudanar da kimantawa na electrochemical na silicon-CB composite abu, silicon-CB composite abu da aka yi amfani da wani taro juzu’i na 80wt% a matsayin aiki abu carbon baki slurry shirya anode.
