Graphite yozungulira yakhala chinthu chofunikira kwambiri pa mabatire amakono a lithiamu-ion omwe amagwiritsidwa ntchito m'magalimoto amagetsi, makina osungira mphamvu, komanso zamagetsi. Pamene kufunikira kwa mphamvu zambiri padziko lonse lapansi komanso moyo wautali wa nthawi yozungulira kukuchulukirachulukira, graphite yozungulira imapereka magwiridwe antchito abwino kwambiri poyerekeza ndi graphite yachikhalidwe. Kwa ogula a B2B, kumvetsetsa mawonekedwe ake ndi zomwe akuyenera kuganizira ndi zinthu zomwe zimaperekedwa ndikofunikira kwambiri kuti zitsimikizire kuti batire lipangidwa bwino komanso mopikisana.

Zimene ZimapangaGraphite yozunguliraZofunika mu Machitidwe Amphamvu Otsogola

Graphite yozungulira imapangidwa pogaya ndi kupanga graphite yachilengedwe yozungulira kukhala tinthu tofanana tozungulira. Kapangidwe kabwino kameneka kamathandizira kwambiri kukhuthala kwa ma packing, kuyendetsa magetsi, komanso magwiridwe antchito amagetsi. Malo ake osalala amachepetsa kukana kwa lithiamu-ion kufalikira, kumawonjezera mphamvu ya chaji, komanso kumawonjezera katundu wogwira ntchito m'maselo a batri.

Mu msika wa EV ndi malo osungira mphamvu womwe ukukula mofulumira, graphite yozungulira imalola opanga kukhala ndi mphamvu zambiri pa selo iliyonse pomwe akusunga chitetezo cha ntchito komanso kulimba kwa kayendedwe kake.

Ubwino Wofunika Kwambiri wa Spherical Graphite

• Kuchuluka kwa madzi m'mpopi komwe kumawonjezera mphamvu yosungira mphamvu

• Kuyendetsa bwino kwambiri komanso kukana kwamkati kochepa kuti pakhale mphamvu yofulumira yolipiritsa/kutulutsa

Ubwino uwu umapangitsa kuti ikhale chinthu chodziwika bwino cha anode chomwe chimagwiritsidwa ntchito popereka mphamvu zodalirika komanso zogwira mtima.

Njira Yopangira ndi Makhalidwe a Zinthu

Kupanga graphite yozungulira ya batri kumaphatikizapo kuzunguliza bwino, kugawa, kuphimba, ndi kuyeretsa. Grafite yachilengedwe imapangidwa kaye kukhala mipiringidzo, kenako imalekanitsidwa ndi kukula kwake kuti zitsimikizire kuti ndi yofanana. Mipiringidzo yoyera kwambiri imafuna kuyeretsa kwa mankhwala kapena kutentha kwambiri kuti ichotse zinyalala zachitsulo zomwe zingayambitse zotsatira zoyipa panthawi yochaja.

Graphite yozungulira yophimbidwa (CSPG) imawonjezera moyo wa kuzungulira mwa kupanga gawo lokhazikika la kaboni, zomwe zimapangitsa kuti magwiridwe antchito a kuzungulira koyamba azitha bwino komanso zimachepetsa mapangidwe a SEI. Kufalikira kwa tinthu tating'onoting'ono, malo ozungulira, kuchuluka kwa zinthu, ndi kuchuluka kwa zinthu zodetsedwa zonse zimatsimikiza momwe zinthuzo zimagwirira ntchito m'maselo a lithiamu-ion.

Malo otsika pamwamba amathandiza kuchepetsa kutayika kwa mphamvu kosasinthika, pomwe kukula kwa tinthu tomwe timayang'aniridwa kumaonetsetsa kuti njira zokhazikika zofalitsira lithiamu-ion ndi kulongedza bwino ma electrode.

Kugwiritsa Ntchito Pa EV, Kusungirako Mphamvu, ndi Zamagetsi Zamagetsi

Graphite yozungulira imagwiritsidwa ntchito kwambiri ngati chinthu chachikulu cha anode m'mabatire a lithiamu-ion omwe amagwira ntchito bwino kwambiri. Opanga ma EV amadalira kuti ithandizire kuyendetsa mota nthawi yayitali, kuyatsa mwachangu, komanso kukhazikika kwa kutentha. Opereka makina osungira mphamvu (ESS) amagwiritsa ntchito graphite yozungulira kuti ikhale ndi moyo wautali komanso kutentha kochepa.

Mu zamagetsi zamagetsi, graphite yozungulira imatsimikizira kuti mafoni a m'manja, ma laputopu, mapiritsi, ndi zinthu zogwiritsidwa ntchito zimasungidwa bwino. Zida zamafakitale, zida zamagetsi zosungira, ndi zida zamankhwala zimapindulanso ndi kukhazikika kwake kosalekeza kwamagetsi ndi kupereka mphamvu.

Pamene ukadaulo wa anode wamtsogolo ukusintha—monga zinthu zopangidwa ndi silicon-carbon—graphite yozungulira ikadali gawo lofunikira kwambiri la kapangidwe kake komanso chowonjezera magwiridwe antchito.

Mafotokozedwe a Zinthu ndi Zizindikiro Zaukadaulo

Pa kugula B2B, graphite yozungulira imayesedwa pogwiritsa ntchito miyeso yofunika kwambiri ya magwiridwe antchito monga kuchuluka kwa madzi m'mapopi, kugawa kwa D50/D90, kuchuluka kwa chinyezi, kuchuluka kwa kuipitsidwa, ndi malo enaake. Kuchuluka kwa madzi m'mapopi kumawonjezera kuchuluka kwa zinthu zogwira ntchito mu selo iliyonse, zomwe zimapangitsa kuti mphamvu zonse zituluke.

Graphite yozungulira yokhala ndi zokutira imapereka ubwino wowonjezera pa ntchito zochaja mwachangu kapena zozungulira kwambiri, ndipo kufanana kwa zokutira kumakhudza kwambiri magwiridwe antchito ndi moyo wa batri. Zipangizo za EV nthawi zambiri zimafuna kuyera kwa ≥99.95%, pomwe ntchito zina zimatha kukwaniritsa zofunikira zosiyanasiyana.

Zoganizira za Unyolo Wopereka kwa Ogula a B2B

Pamene magetsi padziko lonse lapansi akuchulukirachulukira, kuonetsetsa kuti graphite yapamwamba kwambiri yapezeka mosavuta kwakhala chinthu chofunikira kwambiri. Kapangidwe ka tinthu tating'onoting'ono, kuyera, ndi kukonza pamwamba ndikofunikira kwambiri pochepetsa kusiyana kwa kupanga ndikuwonjezera mphamvu ya batri.

Kukhalitsa ndi chinthu china chofunikira. Opanga otsogola akusinthira ku njira zoyeretsera zachilengedwe zomwe zimachepetsa kutayika kwa mankhwala ndi kugwiritsa ntchito mphamvu. Zofunikira pa malamulo a m'madera—makamaka ku Europe ndi North America—zimakhudzanso njira zogulira.

Mapangano a nthawi yayitali, kuwonekera bwino kwa deta yaukadaulo, ndi kuwunika kwa mphamvu za ogulitsa ndizofunikira kwambiri kuti pakhale mphamvu zopikisana zopangira.

Mapeto

Graphite yozungulira imagwira ntchito yofunika kwambiri pakulimbikitsa makampani opanga mabatire a lithiamu-ion padziko lonse lapansi, kupereka magwiridwe antchito ofunikira pa ma EV, machitidwe a ESS, ndi zamagetsi apamwamba. Kuchuluka kwake, mphamvu yake yoyendetsera magetsi, komanso kukhazikika kwake zimapangitsa kuti ikhale yofunika kwambiri kwa opanga omwe akufuna kugwiritsa ntchito bwino mphamvu komanso moyo wautali. Kwa ogula a B2B, kuwunika katundu wazinthu, ukadaulo wopanga, komanso kudalirika kwa ogulitsa ndikofunikira kuti apeze mwayi wopikisana kwa nthawi yayitali pamsika waukadaulo wamagetsi womwe ukukula mwachangu.
