I-Raw Material Ye-Artificial Graphite Anode

1. Ingqikithi Yomkhiqizo

I-Raw Material ye-Artificial Graphite Anodes iyimpushana esebenzayo elungiswe izinqubo ezinembayo ezifana-ne-carbonization, ukuchotshozwa, ukuhlanzwa, nokugreda, -ene-coke yenaliti ehlanzekile, i-petroleum coke, noma{2}i-coke esekelwe emalahleni njenge-core substrate. Kuyisandulela esibalulekile sokukhiqizwa kwama-electrode angalungile e-graphite amabhethri e-lithium. Ivelu yayo eyinhloko ilele ekunikezeni-ama-substrates ekhwalithi ephezulu ukuze kucutshungulwe i-graphitization elandelayo ngokulawula okunembile kokwakheka kwamakhemikhali nesakhiwo somzimba, ekugcineni enikeza ama-electrode enziwe nge-graphite negative anokuhamba kahle kakhulu, ukuzinza kokuhamba ngebhayisikili, nokusebenza kwesilinganiso, okuhlangabezana nezidingo ezibalulekile zamabhethri e-lithium "zomthamo ophezulu, impilo ende, nokuphepha okuphezulu".

2.Izinhlaka Ezibalulekile Zobuchwepheshe

3.Izici Ezimqoka Zomkhiqizo

(1) Okuqukethwe Kwekhabhoni Ephezulu kanye Nokungcola Okuphansi

Okuqukethwe kwekhabhoni engaguquki Kukhulu noma kulingana no-98.5% ({1}}izicaciso zebanga lamandla aphezulu Okukhulu noma kulingana no-99.5%), okuqukethwe komlotha Kungaphansi noma kulingana no-0.3% (inani lokuqukethwe kokungcola kwensimbi okufana ne-Fe, Ni, Cu Ingaphansi noma ilingana no-50ppm), okuqukethwe kwesulfure Okungaphansi noma okulingana ne-nitrogen0, Okuqukethwe kwe-nitrogen noma okulingana no-1%. 0.2%; Isici sokungcola okuphansi singagwema ukusabela okuseceleni phakathi nokuhamba kwebhethri, sinciphise ukubola kwe-electrolyte, futhi siqinisekise ukuqina kwesixhumi esibonakalayo se-electrode engalungile.

(2) I-Optimized Particle Morphology kanye Nokusabalalisa Usayizi Wezinhlayiyana

Nge-Raw Material ye-Artificial Graphite Anodes, izinhlayiya ziyindilinga noma azilingani ngesimo, zinendawo ebushelelezi futhi azikho imiphetho ebukhali (ukugwema ukunwaya i-substrate ngesikhathi sokumbozwa kwe-electrode); ukusatshalaliswa kosayizi wezinhlayiyana kugxilile (D50=10-50μm, Span=0.8-1.2), futhi kungenziwa ngendlela oyifisayo ngokuya ngezidingo zokujiya zepuleti le-electrode elinegethivu. Ilungele izinqubo zokukhiqiza ezinokuminyana okuhlukile (1.6-1.8g/cm³) ukuze kuthuthukiswe ukuhambisana kwepuleti le-electrode.

(3) Ukusebenza Okuhle Kakhulu Kwe-Graphitization

Kukhona amandla amakhulu okuthuthukisa i-graphitization degree. Ngemuva-okuphezulu kwe-graphitization yezinga lokushisa ku-2800-3000℃, i-graphitization℃ingafinyelela ngaphezu kuka-90%, futhi i-lattice constant (c0) Ingaphansi noma ilingana no-0.3356nm; Ngesikhathi senqubo ye-graphitization, izinga lokuncipha kwevolumu lihlala lizinzile (Ngaphansi noma lilingana no-5%), okunganciphisa ingozi yokuqhekeka emikhiqizweni ye-electrode engalungile futhi kunciphise ukulahlekelwa kokukhiqiza.

(4)Ukuguquguquka Kwenqubo Enhle

Impushana inokugeleza okuhle kakhulu (i-angle yokuphumula Ngaphansi noma ilingana nama-degree angu-38) futhi ixubene kalula ngokulinganayo nama-binders (njenge-PVDF) ukuze kwakheke uhlelo oluzinzile lwe-slurry; Phakathi nenqubo yokuhlanganisa, ine-plasticity eqinile futhi ayijwayele ukuphuka kwezinhlayiya, iqinisekisa izakhiwo zemishini ye-electrode futhi ivumelane nemigqa yokukhiqiza ezenzakalelayo.

 

 

4. Izindawo Zokufaka Isicelo Eziyinhloko

(1) Inkambu Yebhethri Yamandla Lithium

Isetshenziselwa ukukhiqizwa kwama-electrode angalungile e-graphite amabhethri amasha emoto yamandla, ane-conductivity ephezulu nezici eziphansi ze-polarization, ithuthukisa izinga lebhethri lokushaja nokusebenza kokushajwa (isekela ukushaja okusheshayo kwe-1C-3C), kuyilapho iqinisekisa impilo yomjikelezo izikhathi ezingaphezu kuka-2000, ihlangabezana nezidingo zebanga lemoto kanye nempilo yesevisi.

(2) I-Energy Storage Lithium Battery Field

Ifanele ama-electrode ebhethri e-lithium angasebenzi eziteshini zamandla okugcina amandla (njengamandla e-photovoltaic namandla omoya asekela isitoreji samandla), okuqukethwe kokungcola okuphansi kunganciphisa izinga lokuzikhipha kwebhethri{-lokukhipha inyanga nenyanga Ngaphansi noma elilingana no-3%), nokusebenza okuzinzile kwe-graphitization kuqinisekisa izinga eliphansi lokushajwa komthamo webhethri{{}3}4{{}3} imijikelezo (imijikelezo eyi-1000 ukuwohloka Ngaphansi noma ilingana no-15%).

(3) Inkambu yebhethri ye-Consumer Electronics Lithium

Isetshenziswa njenge-electrode eyinegethivu yamabhethri e-lithium kumadivayisi kagesi ekhasimende afana nama-smartphone namakhompyutha aphathekayo, ukusatshalaliswa kosayizi wezinhlayiyana ngokwezifiso kungafinyelela ukuncipha kwe-electrode (ugqinsi lwe-electrode Ngaphansi noma okulingana no-80μm) futhi kuthuthukise ukuminyana kwamandla ebhethri ({1}}ngamandla aphezulu ama-electrode, ingafinyelela ukuminyana kwamandla evolumu kuya ku-4³/W noma h).

(4) Inkambu Yebhethri Ye-Lithium Ekhethekile

Isetshenziswa njenge-electrode eyinegethivu kumabhethri e-lithium-ezindaweni zethempelesha eziphezulu (ezifana nemishini yokulawula izimboni) noma{1}}izindawo ezinethempelesha eziphansi (njengamathuluzi angaphandle), ibhethri igcina ukusebenza kokukhipha okuzinzile (izinga lokugcinwa kwamandla Okukhulu noma elilingana no-80%) ku- -20℃-60℃degree ngokulawula ukungcola kwe-graphit degree.

Amashadi ashisayo: impahla eluhlaza ye-graphite anode yokwenziwa, impahla eluhlaza yaseChina yabakhiqizi bokwenziwa kwe-graphite anode
