Umbhalo / i-Chen Gang inexesha elide, ixabiso eliphezulu kunye nokusebenza okuphantsi kweebhetri zemoto zombane ziye zanciphisa ukuphuhliswa kwezithuthi zombane, eziye zaba "ixhala le-mileage" yezithuthi zombane. Ukuqhawula ingxaki yokutshaja kwelinye icala, inkampani yemoto yombane ibonelela ngendlela yokutshintsha ibhetri, njengakwiminyaka emininzi eyadlulayo, ilaptop iyafana, khupha ibhetri, ibhetri efanayo, kodwa ngenxa yesikhululo samandla ombane. Ke ngoko, kwelinye icala, ngetekhnoloji yebhetri ehlala igqobhoza, i-mileage yokuhlaziya iyaqhubeka nokunyuka, inzuzo yemowudi yokutshaja ngokukhawuleza yezithuthi zombane iyanda.

Kule mihla, ikomkhulu ekuqalisweni kwe-Estonia, iSkeleton kunye neJamani iKarlsruhe Institute of Technology igqibe itekhnoloji yebhetri ephezulu kwiimoto zombane, ibhetri yegraphene enje inokuthi itshajwe ngokupheleleyo kwimizuzwana eli-15. Ngokukodwa, le yipakethi yebhetri exubeneyo edibanisa iibhetri ze-lithium-ion eziqhelekileyo kunye neebhetri ze-Skeleton&39;s supercapacitor ezidlala izibonelelo zazo kumsebenzi wokusebenzisana. Ukusuka kwizinto eziluncedo kunye nokungalunganga kweebhetri ze-lithium-ion, ibhetri ye-lithium ion inoxinano lwamandla amaninzi, okuthetha ukuba banokugcina umthamo omkhulu wamandla, kodwa ubuninzi babo bamandla buhlala buphantsi, oku kuthetha ukuba intlawulo yabo kunye nesantya sokukhupha sicotha.

Kwii-supercapacitors, ii-supercapacitors ziyakwazi ukugcina iintlawulo, kunokuba zigcinwe kwiifom zekhemikhali, ngoko ke zibonelela ngoxinano lwamandla amakhulu, zihlawule kwaye zikhuphe ngesantya esiphezulu, kwaye zinokuhlala amakhulu amawaka emijikelezo ngaphandle kokuthotywa. Ngelo xesha, ubuninzi babo bamandla bubi kakhulu xa kuthelekiswa nombane we-lithium; ukuba ufuna ukugcina amandla afanayo, kufuneka ube nebhetri enkulu kunebhetri ye-lithium efanayo. Ngaloo ndlela, xa iSkeleton idibanisa ezinye izinto ze-supercapacitor kwibhetri ye-lithium ion, iphumelele isisombululo esikhangayo kwisisombululo esihle kakhulu.

Njengebhetri yegraphene eyimpumelelo, ixesha lokutshaja kwayo yimizuzwana eyi-15 kuphela. Eli xesha lokutshaja okukhawulezayo kunye namakhulu amawaka emijikelo yokutshaja, ukwenza ibhetri ephezulu iya kuba sisisombululo esifanelekileyo kwimiba emithathu ebalulekileyo echaphazela izithuthi zombane kwixesha elizayo: ixesha lokutshaja liyacotha, ukuthotywa kwebhetri kunye noxinzelelo lonyamezelo. Ngokucacileyo, xa ibhetri ephezulu iya kwimarike, iya kudala amathuba amaninzi kunye neendawo zomoya kwizithuthi zombane.
