I-Spherical graphite isiphenduke into eyisisekelo ye-anode yamabhethri e-lithium-ion yesimanje asetshenziswa ezimotweni zikagesi, izinhlelo zokugcina amandla, kanye nezinto zikagesi zabathengi. Njengoba isidingo somhlaba wonke sokuminyana kwamandla aphezulu nempilo yomjikelezo omude ikhula ngesivinini, i-spherical graphite inikeza ukusebenza okuphakeme uma kuqhathaniswa ne-flake graphite evamile. Kubathengi be-B2B, ukuqonda izakhiwo zayo nokucatshangelwa kokunikezela kubalulekile ekuqinisekiseni ukukhiqizwa kwebhethri okuzinzile futhi okuncintisanayo.

Yini EyenzayoI-Spherical GraphiteIbalulekile ku-Advanced Energy Systems

I-graphite eyindilinga ikhiqizwa ngokugaywa nokubumba i-graphite ye-flake yemvelo ibe yizinhlayiya eziyindilinga ezifanayo. Le morphology eyenziwe kahle ithuthukisa kakhulu ukuminyana kokupakisha, ukuqhutshwa kukagesi, nokusebenza kwe-electrochemical. Indawo yayo ebushelelezi inciphisa ukumelana nokusabalalisa kwe-lithium-ion, ithuthukisa ukusebenza kahle kokushaja, futhi ikhuphule ukulayishwa kwezinto ezisebenzayo kumaseli ebhethri.

Emakethe ekhula ngokushesha ye-EV kanye nesitoreji samandla, i-graphite eyindilinga yenza abakhiqizi bakwazi ukuthola umthamo ophakeme ngeseli ngenkathi begcina ukuphepha kokusebenza kanye nokuqina komjikelezo.

Izinzuzo Zokusebenza Ezibalulekile Ze-Spherical Graphite

• Ukuminyana kompompi okuphezulu okwandisa umthamo wokugcina amandla

• I-conductivity enhle kakhulu kanye nokumelana okuphansi kwangaphakathi kokushaja okusheshayo / ukusebenza kokukhipha

Lezi zinzuzo ziyenza ibe into encanyelwayo ye-anode yezinhlelo zokusebenza ezidinga ukulethwa kwamandla okuthembekile, asebenza kahle kakhulu.

Inqubo Yokukhiqiza kanye Nezici Zokubalulekile

Ukukhiqiza i-graphite eyindilinga yezinga lebhethri kuhlanganisa ukunemba ukuzungezisa, ukuhlukaniswa, ukumbozwa, nokucwengwa. I-graphite ye-flake yemvelo iqala ukubunjwa ibe yizindilinga, bese ihlukaniswa ngosayizi ukuze kuqinisekiswe ukufana. Amabanga aphezulu adinga ukuhlanzwa kwamakhemikhali noma izinga lokushisa eliphezulu ukuze kukhishwe ukungcola kwensimbi okungase kubangele ukusabela okuseceleni phakathi nokushaja.

I-coated spherical graphite (CSPG) ithuthukisa impilo yomjikelezo ngokwenza isendlalelo sekhabhoni ezinzile, esithuthukisa ukusebenza kahle komjikelezo wokuqala futhi sinciphise ukwakheka kwe-SEI. Ukusatshalaliswa kosayizi wezinhlayiya, indawo engaphezulu, ukuminyana kwenqwaba, namazinga okungcola konke kunquma ukuthi umsebenzi usebenza kanjani kumaseli e-lithium-ion.

Indawo ephansi isiza ukunciphisa ukulahleka kwamandla okungenakuhlehliswa, kuyilapho usayizi wezinhlayiyana olawulwayo uqinisekisa izindlela ezizinzile zokusabalalisa i-lithium-ion kanye nokupakishwa kwe-electrode okulinganiselayo.

Izicelo Ku-EV Yonkana, Isitoreji Samandla, kanye Nogesi Wabathengi

I-graphite eyindilinga isetshenziswa kabanzi njengento eyinhloko ye-anode kumabhethri e-lithium-ion asebenza kakhulu. Abakhiqizi be-EV bathembele kuyo ukuze isekele ibanga elide lokushayela, ukushaja okusheshayo, nokuzinza kwe-thermal. Abahlinzeki besistimu yokulondoloza amandla (ESS) basebenzisa i-graphite eyindilinga ukuphila komjikelezo omude kanye nokukhiqiza ukushisa okuphansi.

Kuma-electronics omthengi, i-graphite eyindilinga iqinisekisa ukugcinwa komthamo ozinzile kuma-smartphones, amakhompyutha aphathekayo, amaphilisi, nezinto ezigqokwayo. Amathuluzi ezimboni, amayunithi amandla ekhophi yasenqolobaneni, nemishini yezokwelapha nayo iyazuza ekuzinzeni kwayo okungaguquki kwe-electrochemical kanye nokulethwa kwamandla.

Njengoba ubuchwepheshe be-anode besikhathi esizayo buguquka—njengezinhlanganisela ze-silicon-carbon—i-graphite eyindilinga ihlala iyisakhi esibalulekile sesakhiwo nesithuthukisi sokusebenza.

Ukucaciswa Kwempahla kanye Nezinkomba Zobuchwepheshe

Ekuthengeni kwe-B2B, i-spherical graphite ihlolwa kusetshenziswa amamethrikhi okusebenza angukhiye afana nokuminyana kompompi, ukusatshalaliswa kwe-D50/D90, okuqukethwe umswakama, amaleveli okungcola, nendawo ethile. Ukuminyana kokuthepha okuphezulu kwandisa inani lezinto ezisebenzayo kuseli ngayinye, kuthuthukisa ukuphuma kwamandla okuphelele.

I-graphite eyisiyingi ehlanganisiwe inikezela ngezinzuzo ezengeziwe zokushaja okusheshayo noma izinhlelo zokusebenza zomjikelezo omkhulu, ngokufana kokumboza kuthonya kakhulu ukusebenza kahle nempilo yebhethri. Izinto ze-EV-grade ngokuvamile zidinga ukuhlanzeka okungu-≥99.95%, kuyilapho ezinye izinhlelo zokusebenza zingafaka ukucaciswa okuhlukile.
