Futhi ama-supercapacitor ayizinhlobo ezimbili zamadivayisi wokugcina amandla anamandla amakhulu nokusetshenziswa okubanzi. Izimiso zabo, izici kanye nobubanzi bokusetshenziswa kuhlukile, futhi ngayinye inezinzuzo zayo. Kusukela ekuqaleni, i-graphene ibilokhu inconywa njengento eshintshayo yokugcina amandla ngenxa yokuguquguquka kwayo okunamandla kagesi.

Imizuzu emi-5 ukushaja! Amakhilomitha angama-500! Ukunikezwa kwamandla kwebhethri ye-graphene akukhathazeki!

I-graphene iyifilimu eyisicaba ye-monoatomic eyakhiwe ama-athomu ekhabhoni. Iwugqinsi ngo-0.34 nanometers kuphela. Ungqimba olulodwa luphindwe izikhathi ezingu-150,000 ububanzi bezinwele zomuntu. Njengamanje iyi-nanomaterial encane futhi enamandla kunawo wonke eyaziwa emhlabeni, enamandla okudlulisa ukukhanya nekhono lokugoqa. Ngenxa yokuthi kunongqimba olulodwa kuphela lwama-athomu futhi ama-electron avalelwe endizeni eyodwa, i-graphene iphinde ibe nezinto ezintsha sha zikagesi. I-graphene iyinto esebenza kakhulu emhlabeni. I-graphene composite conductive powder yengezwa kubhethri ye-lithium yocingo yendabuko ukuze kuthuthukiswe ukushajwa kwebhethri nokusebenza kokukhipha nempilo yomjikelezo.

Kodwa-ke, ubunzima bezobuchwepheshe kunqubo yokulungiselela buyisithiyo esikhulu ekuboneni amandla e-graphene. Okwamanje, ubuchwepheshe obuningi bebhethri ye-graphene busesesigabeni sokuthuthukiswa kokuhlolwa. Ingabe ngempela kufanele silinde isikhathi eside?

Muva nje, i-Polycarbon Power, inkampani ephethwe ngokuphelele ye-Zhuhai Polycarbon Composite Materials Co., Ltd., isungule umkhiqizo webhethri we-graphene wezohwebo, iletha amabhethri e-graphene endaweni yaselabhorethri emakethe yamabhethri, futhi yaxazulula ngempumelelo inkinga yamabhethri e-graphene. . Isivinini sokushaja esingazinzile, kanye nomthamo ophansi wamabhethri akhona kakade.

I-Zhuhai Polycarbon yamukela umqondo wokuklama webhalansi yokusebenza okuphelele, ngobuhlakani yethula izinto ezintsha zekhabhoni eziyinhlanganisela esekwe ku-graphene kuma-electrode amabhethri e-capacitor, futhi ihlanganisa ama-supercapacitor ajwayelekile namabhethri anamandla amakhulu ukuze kwakhiwe uhlobo olusha lwebhethri elisebenza kakhulu. .

Okokuqala, amabhethri e-graphene azofakwa kuqala kumabhethri emoto kagesi. Kulindeleke ukuthi bazokwazi ukuhlangana nabasebenzisi ekupheleni kwalo nyaka noma ekuqaleni konyaka ozayo. Engxenyeni yesibili yonyaka ozayo, amabhethri e-graphene okuhweba emkhakheni wezinhlelo zokusebenza zebhethri leselula nawo azokubona. Ngaleso sikhathi, amabhethri omakhalekhukhwini Impilo yokushaja amandla okushaja okusheshayo kanye nezinkinga zokuphepha zingaxazululwa ngayinye ngayinye.

Umsebenzi we-Zhuhai Polycarbon Composite Materials Co., Ltd. wethule ukuthi amabhethri e-lithium iron phosphate namabhethri e-lithium manganese acid angamabhethri emoto kagesi avamile emakethe. Lezi zinhlobo ezintathu zamabhethri zinobuhle nobubi bazo, kodwa abathengi bezimoto bangakhetha amabhethri ahlukene ngokuya ngobuhle nobubi bawo. Kukhona nebhethri ye-graphene, okuwuhlelo olusha olungavimbela ukusha okuzenzakalelayo njengebhethri likaTesla.

I-Polycarbon Power ibambe ubuchwepheshe bokulungiselela amabhethri e-graphene. Ukwengeza i-graphene ezintweni ezinhle ze-electrode kanye nezinto ezibonakalayo ze-electrode yebhethri ye-lithium kunciphisa ukumelana kwangaphakathi kwebhethri, ngaleyo ndlela kuqaphele ukushaja nokukhipha isivinini esisheshayo, futhi kuthuthukisa kakhulu impilo yomjikelezo webhethri. Iphinde ithuthukise ukusebenza kwebhethri ukuze imelane namazinga okushisa aphezulu naphansi. Lona ubuchwepheshe obuyinhloko bePolycarbon Power, obungenakukopishwa ezinye izinkampani. Ukuduma kwamabhethri e-graphene kuzoba ukugxuma kwezimoto zikagesi. Uma amabhethri e-graphene esetshenziswa ezimotweni zikagesi, azoba nezinguquko eziphazamisayo kuyo yonke imboni yezimoto.

‘S core technology

Imfihlakalo yobuchwepheshe ewumongo iwukwamukela umqondo wokuklama webhalansi yokusebenza okuphelele, futhi ngobuhlakani sethule izinto ezintsha zekhabhoni eziyinhlanganisela esekwe ku-graphene kuma-electrode amahle namabi wamabhethri e-capacitor ukufeza inhlanganisela yama-supercapacitor ajwayelekile namabhethri anamandla amakhulu, ngaleyo ndlela kuhlanganiswe amandla. ukusebenza okuhle kakhulu kwama-supercapacitor ajwayelekile namabhethri Ahlanganisiwe.

ukusetshenziswa

Ibhethri le-graphene all-carbon capacitor liwumthombo wamandla wendawo yonke omusha. Ingakwazi ukuxazulula inkinga yamandla ezimoto zikagesi, futhi ingasetshenziswa emikhunjini yangaphezulu, imikhumbi-ngwenya, izimoto zasemoyeni ezingenamuntu, imicibisholo nezinkundla ze-aerospace. Ikakhulukazi, ukusebenza kwayo okuyingqayizivele kokuphepha kuzoba nomthelela omkhulu ekuthuthukisweni kwemboni yezimoto zikagesi. Lo mkhiqizo uhlanganisa izinzuzo zokuminyana kwamandla amabhethri e-lithium kanye nokuminyana kwamandla ama-supercapacitor. Ngokwendinganiso kazwelonke entsha, impilo yomjikelezo womkhiqizo ingafinyelela izikhathi ezingaphezu kuka-4000, futhi izinga lokushisa lokusebenza lisukela ku-minus 30 degrees Celsius kuya ngaphezulu kuka-70 degrees Celsius. Ngokwesisekelo sokuqinisekisa imayela elithile, ukushaja okusheshayo kwamanje kanye nempilo yomjikelezo omude ingafinyelelwa.

Ukuphumelela kwezobuchwepheshe

Ibhethri elisha eliphelele le-graphene carbon capacity linezinzuzo zomthamo omkhulu, amandla kagesi aguqulwa abe amandla amakhemikhali, bese ekhishwa abe ugesi. Ukuqina kwayo kwamandla kuphakeme kunamabhethri e-lithium amanje angcono kakhulu, futhi ukuminyana kwamandla ama-supercapacitor kuseduze nebhethri kanye nesakhiwo se-capacitor yendabuko. , Bona izinzuzo zamabhethri nama-capacitor.

inzuzo yokusebenza

Iphephile futhi izinzile, ibhethri elisha le-graphene polycarbon capacitor, ngemva kokugcwaliswa ngesibhamu sezipikili, lizojikeleza kancane futhi akukho ukusabela; ngeke liqhume uma libekwe emlilweni.

Isivinini sokushaja siyashesha, futhi ibhethri ye-graphene polycarbon ingashajwa ngamagagasi aphezulu angu-10C. Kuthatha imizuzu engu-6 kuphela ukushajwa ngokugcwele ibhethri elilodwa, futhi ngaphezu kuka-95% kungashajwa ngokugcwele ngemizuzu eyi-10 ngamakhulu amabhethri axhunywe ochungechungeni.

Ukuminyana kwamandla aphezulu, kufika ku-200W/KG~1000W/KG, okulingana nezikhathi ezingaphezu kwezingu-3 zamabhethri e-lithium.

Izinga lokushisa eliphansi elihle kakhulu, lingasebenza endaweni yokususa ama-30 ℃.

Umgomo nokusebenza kwebhethri ye-lithium capacitive kuyahlaziywa ngokugcwele

1. Umgomo wokusebenza wama-supercapacitor namabhethri e-lithium
