Spherical graphite yakhala maziko a anode opangira mabatire amakono a lithiamu-ion omwe amagwiritsidwa ntchito pamagalimoto amagetsi, makina osungira mphamvu, ndi zamagetsi ogula. Pamene kufunikira kwapadziko lonse kwa mphamvu zochulukirapo komanso moyo wautali wozungulira ukuchulukirachulukira, graphite yozungulira imapereka magwiridwe antchito apamwamba poyerekeza ndi graphite yachikhalidwe. Kwa ogula a B2B, kumvetsetsa katundu wake ndi momwe amaperekera ndikofunikira kuti awonetsetse kuti batire yokhazikika komanso yopikisana.

Zomwe ZimapangaZithunzi za Spherical GraphiteZofunikira mu Advanced Energy Systems

Ozungulira graphite amapangidwa ndi mphero ndi kuumba zachilengedwe flake graphite mu yunifolomu ozungulira particles. Mapangidwe okhathamiritsa awa amathandizira kwambiri kachulukidwe wonyamula, madulidwe amagetsi, komanso magwiridwe antchito a electrochemical. Malo ake osalala amachepetsa kukana kwa lithiamu-ion kufalikira, kumathandizira kuyendetsa bwino, ndikuwonjezera zomwe zimagwira ntchito m'maselo a batri.

Pamsika womwe ukukula mwachangu wa EV ndi malo osungiramo mphamvu, ma graphite ozungulira amathandizira opanga kuti akwaniritse kuchuluka kwakukulu paselo iliyonse ndikusunga chitetezo chogwira ntchito komanso kulimba kwa kuzungulira.

Ubwino Wamagwiridwe Ofunika a Graphite Yozungulira

• Kuchulukana kwapampopi komwe kumawonjezera mphamvu yosungiramo mphamvu

• Ma conductivity abwino kwambiri komanso kukana kwamkati kwapang'onopang'ono / kutulutsa mwachangu

Zopindulitsa izi zimapangitsa kukhala chinthu chokondedwa cha anode pamapulogalamu ofunikira odalirika, operekera mphamvu kwambiri.

Njira Yopangira ndi Makhalidwe Azinthu

Kupanga ma graphite ozungulira a batri kumaphatikizapo kuzungulira, kusanja, kuphimba, ndi kuyeretsa. Natural flake graphite imapangidwa koyamba kukhala mabwalo, kenako imasiyanitsidwa ndi kukula kuti zitsimikizire kufanana. Kuyera kwapamwamba kumafuna kuyeretsa kwa mankhwala kapena kutentha kwambiri kuti muchotse zonyansa zachitsulo zomwe zingayambitse kuyabwa m'mbali pakulipiritsa.

Coated spherical graphite (CSPG) imathandizira moyo wozungulira ndikupanga wosanjikiza wokhazikika wa kaboni, womwe umathandizira kuyendetsa bwino koyambira ndikuchepetsa mapangidwe a SEI. Kugawa kwa tinthu tating'onoting'ono, kumtunda, kuchuluka kwachulukidwe, komanso kuchuluka kwa zonyansa zonse zimatsimikizira momwe zinthu zimagwirira ntchito m'maselo a lithiamu-ion.

Malo otsika amathandizira kuchepetsa kuwonongeka kwa mphamvu kosasinthika, pomwe kukula kwa tinthu komwe kumayendetsedwa kumatsimikizira njira zosakanikirana za lithiamu-ion komanso kulongedza moyenera ma elekitirodi.

Ma Applications Across EV, Energy Storage, ndi Consumer Electronics

Ma graphite ozungulira amagwiritsidwa ntchito kwambiri ngati chinthu choyambirira cha anode pamabatire a lithiamu-ion apamwamba kwambiri. Opanga ma EV amadalira kuti azithandizira kuyendetsa kwautali, kuthamangitsa mwachangu, komanso kukhazikika kwamafuta. Othandizira osungira mphamvu (ESS) amagwiritsa ntchito graphite yozungulira kwa moyo wautali komanso kutentha kochepa.

Pamagetsi ogula, ma graphite ozungulira amaonetsetsa kuti mafoni a m'manja, ma laputopu, mapiritsi, ndi zovala zimasungidwa mokhazikika. Zida zamafakitale, zida zamagetsi zosunga zobwezeretsera, ndi zida zamankhwala zimapindulanso ndi kukhazikika kwake kosasinthika kwa electrochemical komanso kupereka mphamvu.

Pamene matekinoloje a anode amtsogolo akusintha-monga ma silicon-carbon composites-spherical graphite imakhalabe gawo lofunikira komanso chothandizira ntchito.

Mfundo Zazida ndi Zizindikiro Zaukadaulo

Pogula B2B, ma graphite ozungulira amawunikidwa pogwiritsa ntchito ma metrics ofunikira monga tap density, kugawa kwa D50/D90, chinyezi, kuchuluka kwa zonyansa, ndi malo enaake. Kuchuluka kwapampopi kumawonjezera kuchuluka kwa zinthu zomwe zimagwira mu cell iliyonse, ndikuwongolera mphamvu zonse.

Coated spherical graphite imapereka maubwino owonjezera pakulipiritsa mwachangu kapena kugwiritsa ntchito mozungulira kwambiri, kufananiza kwa zokutira kumathandizira kwambiri magwiridwe antchito komanso moyo wa batri. Zida zamakalasi a EV nthawi zambiri zimafunikira ≥99.95% chiyero, pomwe ntchito zina zitha kutengera mawonekedwe osiyanasiyana.
