Chidule
GMCC yapanga bwino makina atsopano a 5000F ultracapacitor okhala ndi mphamvu zambiri (＞10 Wh/kg) mu kukula kokhazikika kwa 60138, omwe angapereke mphamvu zambiri, kuyitanitsa ndi kutulutsa nthawi yomweyo, kudalirika kwambiri, kupirira kutentha kwambiri, komanso moyo wautumiki wopitilira 1,000,000 nthawi imodzi. Selo ya GMCC 5000F imatha kukulitsa kwambiri chithandizo cha inertia komanso kuthekera kwa modulation ya ma frequency oyambira pa gridi yamagetsi, ndikukweza magwiridwe antchito a zida mu netiweki. Pakadali pano, selo ya GMCC 5000F imatha kukwaniritsa kuyambika kozizira kotsika, chithandizo chamagetsi, kubwezeretsa mphamvu, magetsi otsika olamulidwa ndi waya pamagalimoto ndi ntchito zina zamagetsi.
Chiyambi
Ma Ultracapacitors, monga gwero lamphamvu lodalirika kwambiri lomwe limapereka mphamvu zamagetsi zambiri pakanthawi kochepa, lakopa chidwi chowonjezeka masiku ano. Ndi kuchulukirachulukira kwa magetsi padziko lonse lapansi, khama lalikulu lapangidwa kuti liwongolere kuchuluka kwa mphamvu ndi mphamvu, ubwino, chitetezo, komanso kuchepetsa mtengo wa zida zosungira mphamvu. Ma Ultracapacitor akuvomerezedwa kwambiri ngati njira zosungira mphamvu zomwe zimathandiza kugwiritsa ntchito magalimoto monga advanced driving assistance (ADAS), innovative suspension and anti-roll bar systems, ndi advanced emergency braking system (AEBS), ndi zina zotero. Posachedwapa, poyang'anizana ndi kulumikizana kwakukulu kwa mphamvu zoyera monga photovoltaic ndi wind power, akuyembekezeka kuti ma ultracapacitor adzayambitsa chitukuko chofulumira m'makina atsopano amagetsi, monga power grid frequency modulation.

Ukadaulo wa 5000F Ultracapacitor
Pakadali pano, mphamvu yayikulu ya selo mumakampani opanga ma supercapacitor ndi 3000F yokha, ndipo chifukwa chakuti malo enieni a kaboni woyatsidwa mu ma electrode abwino ndi oipa sagwiritsidwa ntchito bwino, kuchuluka kwa kugwiritsa ntchito bwino kwamakono ndi pafupifupi 10%. Ngati botolo la mphamvu ndi zofooka za ma ultracapacitors zasweka, zatsopano ndi zosintha zina zofunika ziyenera kupangidwa kuchokera ku kapangidwe ka zinthu, mawonekedwe olimba, ndi makina amagetsi.
GMCC yachita njira zambiri zokonzera ukadaulo, kuphatikizapo kuchuluka kwa mamolekyulu/ionic, kukula kwa kapangidwe ka zinthu zazing'ono ndi zazing'ono, kukula kwa mawonekedwe a zinthu zazing'ono zolimba-zamadzimadzi, kukula kwa tinthu tating'onoting'ono ta zinthu, kukula kwa makina amagetsi amphamvu, kapangidwe ka kapangidwe ka maselo, ndi zina zotero. Choyamba, kapangidwe ka ma pore ndi mawonekedwe a pamwamba pa zinthu za kaboni zasanthulidwa mozama ndikukonzedwa bwino, ndipo zinthu za kaboni zapangidwa mwapadera ndi kapangidwe ka ma pore ozungulira (ma micropores, mesopores, ndi macropores sizimalepheretsedwa). Kachiwiri, zizindikiro zazikulu monga kukula kwa ma ion, ntchito ya ma ion, mphamvu yosungunula, kukhuthala kwa electrolyte zaganiziridwa mokwanira. Kutengera ndi kafukufuku wofananira wa mawonekedwe a zinthu/electrolyte solid-liquid, malo enieni a kaboni woyatsidwa amagwiritsidwa ntchito mokwanira, ndipo kuchuluka ndi kuthekera kwa mphamvu yoyatsidwa pamwamba kumawonjezeka kwambiri. Kachitatu, cholekanitsa chapadera chimapangidwa ndi zinthu zopangidwa ndi ulusi wophatikizika, ndipo chili ndi mawonekedwe a mphamvu yayikulu, ma porosity apamwamba komanso kuthekera kwakukulu koyamwa madzi. Pambuyo pake njira ya ma electrode ouma osaipitsa imatengedwa kuti ikonze kwambiri kuchuluka kwa ma electrode. Pakadali pano, imapangitsanso kuti selo likhale ndi kukana kwabwino kwa kugwedezeka komanso magwiridwe antchito a moyo, ndipo njira ya glue fibrosis imamatira ndikuzungulira pamwamba pa tinthu tating'onoting'ono kuti ipange kapangidwe ka "khola", komwe kumathandiza kuti electrolyte ilowerere komanso kutumiza ma ayoni. Pomaliza, GMCC imagwiritsa ntchito njira yaukadaulo wa all-tab, all-laser welding, ndipo selo lomwe lapezeka ndi kapangidwe kolimba kolumikizidwa ndi metallurgical komwe kali ndi kukana kocheperako kwa ohmic komanso kukana kwabwino kwambiri kwa kugwedezeka, komwe kumakwaniritsa zofunikira za muyezo wa AECQ200 wamagalimoto.

Pofuna kutchula ultracapacitor yokhala ndi voltage yovomerezeka, selo liyenera kukwaniritsa zofunikira zina. Muyezo wakhazikitsidwa m'makampani m'zaka zaposachedwa. Likasungidwa pa kutentha kwakukulu kogwira ntchito (65oC kwa ma ultracapacitors ambiri) ndi voltage yovomerezeka, selo liyenera kukwaniritsa nthawi yodziwika bwino pamene likukhalabe mkati mwa zofunikira zomwe zafotokozedwa. Nthawi yokhazikika imayikidwa pa maola 1500 kwa opanga ma ultracapacitor ambiri ndipo zofunikira zomwe zafotokozedwazo ndi zochepa kuposa 20% kutayika kwa capacitance wamba komanso kuwonjezeka kwakukulu kwa 100% kwa mtengo wodziwika wa ESR. Chithunzi 2 chikuwonetsa kuti GMCC 5000F ultracapacitor ikhoza kukwaniritsa zofunikira izi.
Chithunzi 2 Kusinthika kwa mphamvu ya GMCC 5000F ultracapacitor (kupotoza kumanzere) ndi ESR (kupotoza kumanja) kumasungidwa kutentha kwa 65 oC ndi voteji ya 2.7V.
Tsogolo
Tikukhulupirira kuti ntchito zofufuza ndi chitukuko zomwe zimayang'ana kwambiri cholinga zidzatithandiza kupititsa patsogolo magwiridwe antchito a maselo onse, makamaka magetsi a maselo. Kutengera zotsatira zaposachedwa za labotale, tikuyembekeza kuti kuchuluka kwa magetsi a maselo otsatira kudzachitika mtsogolomu. Izi zitithandiza kuwonjezera mphamvu ndi kuchuluka kwa mphamvu za GMCC ultracapacitors motero kupitiliza ndi njira zosungira mphamvu zazing'ono komanso zamphamvu kwambiri.
