Isishwankathelo
I-GMCC iphumelele ukuphuhlisa i-ultracapacitor entsha ye-5000F enobunzima obuphezulu bamandla (＞10 Wh/kg) ngobukhulu obuqhelekileyo be-60138, enokubonelela ngobunzima obuphezulu bamandla, ukutshaja nokukhupha ngokukhawuleza, ukuthembeka okuphezulu, ukunyamezela ubushushu obugqithisileyo, kunye nobomi benkonzo obungaphezulu kwe-1,000,000 yemijikelo yokukhupha itshaja ngaxeshanye. Iseli ye-GMCC 5000F inokuphucula kakhulu inkxaso ye-inertia kunye nokukwazi kwe-modulation ye-frequency yokuqala kwigridi yamandla, kwaye iphucule ukusebenza kwezixhobo kwinethiwekhi. Okwangoku, iseli ye-GMCC 5000F inokwanelisa ukuqala kokubanda okuncinci kobushushu, inkxaso yamandla, ukubuyiswa kwamandla, umbane ophantsi olawulwa yintambo kwiimoto kunye nezinye izicelo zamandla.
Intshayelelo
Ii-Ultracapacitors, njengomthombo wamandla othembekileyo kakhulu obonelela ngombane ophezulu ngexesha elifutshane, kuye kwatsala ingqalelo eyandayo kule mihla. Ngenxa yokufakelwa kombane kwihlabathi liphela, kuye kwenziwa imizamo emikhulu yokuphucula uxinano lwamandla kunye namandla, umgangatho, ukhuseleko, kunye nokunciphisa iindleko zezixhobo zokugcina amandla. Ii-Ultracapacitors zamkelwe ngakumbi njengeenkqubo zokugcina amandla ezivumela usetyenziso lweemoto ezifana noncedo lokuqhuba oluphambili (i-ADAS), iinkqubo ezintsha zokumisa kunye neenkqubo ze-anti-roll bar, kunye nenkqubo yokuqhoboshela engxamisekileyo ephucukileyo (i-AEBS), njl. Kwixesha elizayo elingekude, xa kujongwa uqhagamshelo olukhulu lwegridi yamandla acocekileyo afana namandla e-photovoltaic kunye nomoya, kulindeleke ukuba ii-ultracapacitors zizise uphuhliso olukhawulezileyo kwiinkqubo ezintsha zamandla, ezifana nokuguqulwa kwamaza egridi yamandla.
Umfanekiso 1 Iseli ye-GMCC 2.7V 5000F EDLC
Itekhnoloji ye-5000F Ultracapacitor
Okwangoku, amandla aphezulu e-capacitance yeseli kwishishini le-supercapacitor yi-3000F kuphela, kwaye ngenxa yokuba indawo ethile yomphezulu we-activated carbon kwi-electrodes ezilungileyo nezingalunganga ayisetyenziswa ngokufanelekileyo, izinga lokusetyenziswa ngokufanelekileyo ngoku limalunga ne-10% kuphela. Ukuba i-bottleneck yoxinano lwamandla kunye nemida ye-ultracapacitors yaphukile, kufuneka kwenziwe ezinye izinto ezintsha kunye nohlengahlengiso olusisiseko kwisakhiwo sezinto, ujongano oluqinileyo nolwelo, kunye nenkqubo ye-electrochemical.
I-GMCC yenze uphuculo olupheleleyo lobuchwephesha olunemilinganiselo emininzi, olubandakanya isikali se-molecular/ionic, isikali sesakhiwo se-micro kunye ne-nano, isikali se-interface ye-micro solid-liquid yezinto ezibonakalayo, isikali se-particle yezinto ezibonakalayo, uphuhliso lwenkqubo ye-electrochemical ephezulu, uyilo lwesakhiwo seseli, njl. Okokuqala, isakhiwo se-pore kunye neempawu zomphezulu wezinto zekhabhoni zihlalutywe nzulu kwaye zalungiswa, kwaye izinto zekhabhoni ziyilwe ngokukodwa ngesakhiwo se-hierarchical porous esidibanisayo (ii-micropores, ii-mesopores, kunye nee-macropores azithintelwanga ngababini). Okwesibini, izalathisi eziphambili ezifana nobukhulu be-ion, umsebenzi we-ion, isiphumo sokusombulula, i-viscosity ye-electrolyte ziqwalaselwe ngokupheleleyo. Ngokusekelwe kuphononongo oluhambelanayo lwe-interface ye-material/electrolyte solid-liquid, indawo ethile yomphezulu we-activated carbon isetyenziswa ngokupheleleyo kangangoko, kwaye ubungakanani kunye nokukwazi kwe-surface adsorbed charge kuphuculwe kakhulu. Okwesithathu, i-special separator yenziwe ngezinto ze-composite fiber, kwaye ineempawu zamandla aphezulu, i-porosity ephezulu kunye nokukwazi ukufunxa ulwelo okuphezulu. Emva koko inkqubo ye-electrode eyomileyo engangcolisiyo iyasetyenziswa ukuphucula kakhulu uxinano lwe-electrode. Okwangoku, ikwayenza iseli ibe nokumelana okungcono kokungcangcazela kunye nokusebenza ubomi bayo bonke, kwaye inkqubo ye-adhesive fibrosis inamathela kwaye ijikeleza phezu komphezulu wee-particles zezinto ukuze yenze isakhiwo "sekheji", esenza kube lula ukufunxwa kwe-electrolyte kunye nokudluliselwa kwee-ions. Ekugqibeleni i-GMCC yamkela inkqubo yetekhnoloji ye-all-tab, all-laser welding, kwaye iseli efunyenweyo yisakhiwo esidityaniswe ngokuqinileyo se-metallurgical esinokumelana okuncinci kwe-ohmic kunye nokumelana okugqwesileyo kokungcangcazela, esihlangabezana neemfuno zomgangatho we-AECQ200 we-automotive grade.

Ithebhu. 1 GMCC 2.7V 5000F EDLC iinkcazo zombane ezisisiseko zeseli
Ukuze kuchazwe i-ultracapacitor ene-voltage elinganisiweyo, iseli kufuneka ihlangabezane neemeko ezithile. Umgangatho umiselwe kushishino kwiminyaka edlulileyo. Xa igcinwe kubushushu obuphezulu bokusebenza (65oC kwii-ultracapacitors ezininzi) kunye ne-voltage elinganisiweyo, iseli kufuneka ifikelele kwixesha elichaziweyo ngelixa ihlala ngaphakathi kwemigangatho echaziweyo yesiphelo sobomi. Ixesha lokuphila limiselwe kwiiyure ezili-1500 kubavelisi abaninzi be-ultracapacitor kwaye imigangatho yokugqibela yobomi ingaphantsi kwe-20% yokulahleka kwe-capacitance eqhelekileyo kunye nokunyuka okuphezulu kwe-100% yexabiso elichaziweyo le-ESR. Umzobo 2 ubonisa ukuba i-GMCC 5000F ultracapacitor inokuhlangabezana nale miqathango.
Umfanekiso 2 Uphuhliso lwe-Capacitance (ijika lasekhohlo) kunye ne-ESR (ijika lasekunene) ye-GMCC 5000F ultracapacitor egcinwe kubushushu obuyi-65 oC kunye ne-voltage eyi-2.7V.
Ngelixa elizayo
Sikholelwa ukuba imisebenzi ye-R&D ejolise ekujoliswe kuyo, enzulu iya kusinceda ukuba siphucule ngakumbi ukusebenza kweseli iyonke, ingakumbi i-voltage yeseli. Ngokusekelwe kwiziphumo zangoku zelebhu, silindele ukuba inqanaba elilandelayo le-voltage yeseli liza kwenzeka kwixesha elizayo. Oku kuya kusinceda ukuba sonyuse amandla kunye noxinano lwamandla e-GMCC ultracapacitors size ngaloo ndlela sihambisane nomkhwa wokufumana izisombululo zokugcina amandla ezincinci nezinamandla ngakumbi.
