Ukusebenza kakuhle kweCoulombic yokuqala: Imfuneko ye-≥92.6% ibonisa ubungakanani bomthamo oguqukayo wezinto ngexesha lomjikelo wokuqala. Iiparamitha zeSkristal Structure: Isithuba seplane (002) (d002) silawulwa ngovavanyo lwe-X-ray diffraction (XRD) ukuze kuphuculwe idigri yegrafiti, kuncitshiswe iziphene zelattice, kwaye kuphuculwe ukuhamba kwe-electron. 2. Ukusasazwa koBukhulu beeParticle kunye noMphezulu oQhelekileyo
Ukusasazwa koBukhulu beeNgcambu: Ubungakanani obuqhelekileyo beengcambu (D50) kunye nobubanzi bokusasazwa kufuneka kulawulwe ukuze kuphuculwe inkqubo yokulungiselela i-slurry yebhetri kunye noxinano lwamandla e-volumetric. Iingcambu ezincinci ezizalisa izithuba zeengcambu ezinkulu zinokuphucula uxinano lokuxinana. Indawo ethile yoMphezulu: Kufuneka kubekho ibhalansi phakathi komsebenzi wokusabela kunye nokulahleka komthamo wokuqala. Indawo ethile engaphezulu yoMphezulu inyusa ukusetyenziswa kwe-binder kunye nokumelana kwangaphakathi, ngelixa indawo ethile enganeleyo yoMphezulu ithintela ukusebenza kakuhle kwe-lithium-ion deintercalation. 3. Ulawulo lokuCoca kunye nokungacoceki
Umxholo weKhabhoni oZinzileyo: Kufuneka imfuneko ye-≥99.5% ukunciphisa impembelelo yezinto ezingasebenziyo ekusebenzeni kwe-electrochemical. Umswakama kunye nexabiso le-pH: Kufuneka ulawulo oluqinileyo ukuze kuthintelwe ukufunxwa komswakama wezinto okanye ukusabela kwi-electrolyte, okunokuchaphazela ukuzinza kwenkqubo yokulungiselela ulusu.
II. Intsimi ye-Electrode Rod (umz., i-Graphite Electrode)
- Ukuqhuba kunye namandla oomatshini
Ukumelana: Kufuneka ibe phantsi njengenqanaba le-μΩ·m ukunciphisa ukulahleka kwamandla ngexesha lokusetyenziswa kwe-electrode. Amandla okuGuquka: Kufuneka amandla aphezulu okugungqa ukuze kuxhathiswe uxinzelelo loomatshini ngexesha lokusetyenziswa kunye nokuthintela ukwaphuka. I-Elastic Modulus: Ulungelelwano phakathi kokuqina kunye nokuqina luyimfuneko ukuze kuthintelwe ukuqhekeka ngenxa yokutshayiswa kobushushu okanye ukungcangcazela koomatshini. 2. Uzinzo lobushushu kunye nokumelana nokuxinana kwe-Oxidation
I-Coefficient yoKwandiswa koBushushu: Kufuneka ibe sezantsi ukuze kuncitshiswe utshintsho olubonakalayo kubushushu obuphezulu kwaye kuthintelwe ukudibana okungalunganga phakathi kwe-electrode kunye netshaja yesithando somlilo. Umxholo woMlotha: Kufuneka ube yi-≤0.5% ukuze kuncitshiswe impembelelo yokungcola ekuchaseni i-electrode oxidation. Izinto zesinyithi ezikulo thuthu zinokukhawulezisa i-electrode oxidation kwaye zinciphise ubomi benkonzo. 3. Ukuguquguquka kwenkqubo yokuvelisa
Uxinano Olukhulu: Uxinano oluphezulu luyimfuneko ukuphucula uxinano lwe-electrode kunye nokuphucula ukuhanjiswa kwe-electrode kunye nokumelana ne-oxidation. Inkqubo yokufunxa kunye neGraphitization: Ukufakelwa okuninzi kunye negraphitization yobushushu obuphezulu (≥2800°C) kuyafuneka ukuphucula ulungelelwano lwekristale kunye nokunciphisa uxhathiso.
III. Ukubekwa phambili kwesalathisi okuqhutywa yiMibono yesicelo Izinto ze-Lithium-ion Battery Anode: Kufuneka zihlangabezane neemfuno zoxinano olukhulu lwamandla kunye nobomi bomjikelo omde, yiyo loo nto kufuneka zihlangabezane neemfuno ezingqongqo zokusebenza kwe-electrochemical, ukusasazwa kobungakanani bezinto ezincinci, kunye nobunyulu. Ii-Electrode Rods: Kufuneka zisebenze ngokuzinzileyo phantsi kobushushu obuphezulu kunye noxinano oluphezulu lwamandla, ngaloo ndlela kugxininiswa kakhulu ekuqhubeni amandla, amandla oomatshini, kunye nokuzinza kobushushu.
