I-Text / Chen Gang inesikhathi eside, izindleko eziphakeme kanye nokusebenza kahle okuphansi kwamabhethri emoto kagesi kuye kwakhawulela ukuthuthukiswa kwezimoto zikagesi, okuye kwaba "ukukhathazeka kwe-mileage" yezimoto zikagesi. Ukuxazulula inkinga yokushaja ngakolunye uhlangothi, inkampani yezimoto zikagesi ihlinzeka ngendlela yokuguqula ibhethri, njengaseminyakeni eminingi edlule, ikhompuyutha ephathekayo iyafana, khipha ibhethri, ibhethri elifanayo, kodwa ngenxa yesiteshi samandla kagesi Izindleko zokuqala zokutshala imali zendlela kagesi zinkulu kakhulu, indawo yokuphromotha inomkhawulo, futhi ayikwazanga ukuthola umphumela. Ngakho-ke, ngakolunye uhlangothi, ngobuchwepheshe bebhethri buhlala bugqekeza, i-mileage yokuvuselela iyaqhubeka nokukhula, inzuzo yemodi yokushaja okusheshayo yezimoto zikagesi iya ngokuya iphezulu.

Ezinsukwini zanamuhla, Ikomkhulu ekuqalisweni kwe-Estonia, iSkeleton kanye ne-German Karlsruhe Institute of Technology sebeqedile ubuchwepheshe bebhethri abakhulu bezimoto zikagesi, ibhethri elinjalo le-graphene elingashajwa ngokugcwele phakathi kwemizuzwana eyi-15. Ngokukhethekile, leli iphakethe lebhethri elixutshiwe elihlanganisa amabhethri e-lithium-ion ajwayelekile kanye namabhethri e-Skeleton&39;s supercapacitor adlala izinzuzo zawo emsebenzini wokuhlanganyela. Kusukela ebuhleni nasebubini bamabhethri e-lithium-ion, ibhethri ye-lithium ion inomthamo omkhulu wamandla, okusho ukuthi ingakwazi ukugcina inani elikhulu lamandla, kodwa ubukhulu bamandla abo ngokuvamile buphansi kakhulu, okusho ukuthi ukushaja nokukhipha isivinini sabo kuhamba kancane.

Kuma-supercapacitor, ama-supercapacitor angagcina amashaji, kunokuba agcinwe kumafomu amakhemikhali, ngakho-ke ahlinzeka ngokuminyana kwamandla amakhulu, ukushaja nokukhipha ngesivinini esiphezulu, futhi angahlala amakhulu ezinkulungwane zemijikelezo ngaphandle kokwehlisa isithunzi. Ngesikhathi esifanayo, ukuminyana kwabo kwamandla kubi kakhulu uma kuqhathaniswa nogesi we-lithium; uma ufuna ukugcina amandla afanayo, kufanele ube nebhethri elikhudlwana kunebhethri ye-lithium efanayo. Ngakho-ke, lapho i-Skeleton ihlanganisa ezinye izakhi ze-supercapacitor kubhethri ye-lithium ion, ifinyelele isisombululo esikhangayo kakhulu kwisixazululo esikhangayo kakhulu.

Njengebhethri ye-graphene ephumelelayo, isikhathi sayo sokushaja imizuzwana engu-15 kuphela. Lesi sikhathi sokushaja esishesha kakhulu kanye namakhulu ezinkulungwane zemijikelezo yokushaja, okwenza ibhethri elikhulu libe yisixazululo esiphelele ezindabeni ezintathu ezibalulekile ezithinta izimoto ezisebenza ngogesi esikhathini esizayo: isikhathi sokushaja sihamba kancane, ukuwohloka kwebhethri nokukhathazeka kokubekezela. Ngokusobala, lapho ibhethri elikhulu liya emakethe, lizophinde lidale amathuba amaningi nezindawo zomoya zezimoto zikagesi.
