Isifinyezo
I-GMCC iphumelele ukuthuthukisa i-ultracapacitor engu-5000F entsha enobukhulu bamandla obuphezulu (＞10 Wh/kg) ngobukhulu obujwayelekile obungu-60138, enganikeza ubuningi bamandla aphezulu, ukushaja nokukhipha ngokushesha, ukuthembeka okuphezulu, ukubekezelela izinga lokushisa okukhulu, kanye nokuphila kwenkonzo kwemijikelezo engaphezu kuka-1,000,000 yokushaja kanye nokukhipha ngasikhathi sinye. Iseli le-GMCC 5000F lingathuthukisa kakhulu ukwesekwa kwe-inertia kanye nekhono lokuguqulwa kwemvamisa eyinhloko yegridi yamandla, futhi lithuthukise ukusebenza kwemishini kunethiwekhi. Okwamanje, iseli le-GMCC 5000F lingahlangabezana nokuqala okubandayo okusizayo okuphansi, ukwesekwa kwamandla, ukubuyiselwa kwamandla, ukunikezwa kwamandla aphansi okulawulwa ngocingo kwezinhlelo zokusebenza zamandla zezimoto nezinye izimoto.
Isingeniso
Ama-Ultracapacitors, njengomthombo wamandla othembekile kakhulu ohlinzeka ngogesi ophezulu ngesikhathi esifushane, kuye kwadonsela ukunaka okwandayo kulezi zinsuku. Njengoba ugesi womhlaba wonke uqhubeka ukhula, kuye kwenziwa imizamo emikhulu yokuthuthukisa ubuningi bamandla namandla, ikhwalithi, ukuphepha, kanye nokunciphisa izindleko zamadivayisi okugcina amandla. Ama-Ultracapacitor amukelwa ngokwandayo njengezinhlelo zokugcina amandla ezivumela izinhlelo zokusebenza zezimoto ezifana nosizo lokushayela oluthuthukisiwe (i-ADAS), izinhlelo ezintsha zokumiswa kanye ne-anti-roll bar, kanye nesistimu yokubhuleka ephuthumayo ethuthukisiwe (i-AEBS), njll. Esikhathini esizayo esiseduze, lapho kubhekene nokuxhumeka okukhulu kwegridi yamandla yamandla ahlanzekile njenge-photovoltaic kanye namandla omoya, kulindeleke ukuthi ama-ultracapacitor azoletha intuthuko esheshayo ezinhlelweni zamandla amasha, njengokuguqulwa kwemvamisa yegridi yamandla.

Ubuchwepheshe be-Ultracapacitor be-5000F
Njengamanje, amandla aphezulu eseli embonini ye-supercapacitor angama-3000F kuphela, futhi ngenxa yokuthi indawo ethile ebusweni be-activated carbon kuma-electrode amahle nangalungile ayisetshenziswa kahle, izinga lokusetshenziswa okusebenzayo lamanje licishe libe yi-10%. Uma i-bottleneck yamandla kanye nemikhawulo yama-ultracapacitors iphukile, kumele kwenziwe ezinye izinto ezintsha kanye nokulungiswa okuyisisekelo kusukela esakhiweni sezinto ezibonakalayo, isikhombikubona esiqinile-uketshezi, kanye nohlelo lwe-electrochemical.
I-GMCC yenze ukulungiswa kobuchwepheshe okubanzi okunezilinganiso eziningi, okubandakanya isikali sama-molecule/ionic, isikali sesakhiwo sezinto ezincane nezincane, isikali se-interface esiqinile esiqinile esiwuketshezi, isikali sezinhlayiya zezinto, ukuthuthukiswa kwesistimu ye-electrochemical enamandla aphezulu, ukwakheka kwesakhiwo seseli, njll. Okokuqala, isakhiwo se-pore kanye nezici zobuso bezinto zekhabhoni kuhlaziywe ngokujulile futhi kwalungiswa, kanti izinto zekhabhoni zakhiwe ngokukhethekile ngesakhiwo esinama-porous esingena phakathi (ama-micropores, ama-mesopores, nama-macropores awavimbeki nhlangothi zombili). Okwesibili, izinkomba ezibalulekile njengosayizi we-ion, umsebenzi we-ion, umphumela wokuxazulula, i-viscosity ye-electrolyte kucatshangelwe ngokuphelele. Ngokusekelwe ocwaningweni oluhambisanayo lwesikali sezinto/i-electrolyte esiqinile esiwuketshezi, indawo ethile yobuso bekhabhoni esebenzayo isetshenziswa ngokugcwele ngezinga eliphezulu, futhi inani kanye nekhono lokushaja okufakwe ebusweni kuthuthukiswa kakhulu. Okwesithathu, isihlukanisi esikhethekile senziwe ngezinto zefayibha ezihlanganisiwe, futhi sinezici zamandla aphezulu, ama-porosity aphezulu kanye nekhono lokumunca uketshezi oluphezulu. Ngemva kwalokho inqubo ye-electrode eyomile engangcolisi iyasetshenziswa ukuze kuthuthukiswe kakhulu ukuqina kokuqina kwe-electrode. Okwamanje, yenza futhi iseli libe nokumelana okungcono kokudlidliza kanye nokusebenza kahle, futhi inqubo ye-adhesive fibrosis inamathela futhi ijikeleza ebusweni bezinhlayiya zezinto zokwakha ukuze yakhe isakhiwo "sekheji", esiza ekumuncweni kwe-electrolyte kanye nokudluliswa kwama-ion. Ekugcineni i-GMCC yamukela inqubo yobuchwepheshe bokushisela i-all-tab, yonke i-laser, futhi iseli elitholiwe liyisakhiwo esixhunywe ngokuqinile se-metallurgical esinokumelana kokuxhumana okuphansi kwe-ohmic kanye nokumelana okuhle kokudlidliza, okuhlangabezana nezidingo zezinga lezimoto le-AECQ200.

Ithebhu. 1 GMCC 2.7V 5000F EDLC isici sikagesi esiyisisekelo seseli
Ukuze kuchazwe i-ultracapacitor ene-voltage elinganisiwe, iseli kumele lihlangabezane nezimo ezithile. Kuye kwasungulwa indinganiso embonini eminyakeni edlule. Uma igcinwa ekushiseni okuphezulu kokusebenza (65oC kuma-ultracapacitors amaningi) kanye ne-voltage elinganisiwe, iseli kumele lifinyelele isikhathi sokuphila esichaziwe ngenkathi lihlala ngaphakathi kwemigomo yokuphela kokuphila echaziwe. Isikhathi sokuphila sibekwe emahoreni angu-1500 kubakhiqizi abaningi be-ultracapacitor futhi imigomo yokuphela kokuphila ingaphansi kuka-20% ukulahleka kwe-capacitance okujwayelekile kanye nokwenyuka okuphezulu okungu-100% wenani elichaziwe le-ESR. Isibalo 2 sibonisa ukuthi i-GMCC 5000F ultracapacitor ingahlangabezana nalezi zimo.
Isithombe 2 Ukuguquguquka kwe-Capacitance (ijika lesobunxele) kanye ne-ESR (ijika lesokudla) kwe-GMCC 5000F ultracapacitor egcinwe ekushiseni okungu-65 oC kanye ne-voltage engu-2.7V.
Ikusasa
Sikholelwa ukuthi imisebenzi ye-R&D egxile ekuqondisweni, ejulile izosisiza ukuthi sithuthukise ukusebenza kweseli iyonke, ikakhulukazi i-voltage yeseli. Ngokusekelwe emiphumeleni yamanje yelabhorethri, silindele ukuthi izinga elilandelayo le-voltage yeseli lizokwenzeka esikhathini esizayo esibonakalayo. Lokhu kuzosisiza ukuthi sandise amandla namandla e-GMCC ultracapacitors futhi ngaleyo ndlela sihambisane nomkhuba wokuthola izixazululo zokugcina amandla ezincane nezinamandla kakhulu.
