Ukuhamba uhambo kwaye uphethe ithebhulethi yakho okanye itshaja ye-smartphone yinto eqhelekileyo kwaye ibalulekile. Naxa silala phandle ngobunye ubusuku, kufuneka sihambe netshaja ukuze singahlukani nabantu esidibana nabo. I ingxaki ikwi ukuzimela kakubi kweebhetri ze-Li-Ion okanye i-lithium-ion ukuba, nangona baye basinika isisombululo iminyaka, njengoko izixhobo ziqhubela phambili kwaye amandla abo enyuka, bahlala ngakumbi nangaphezulu. iphelelwe lixesha. Uphando olwenziwe eCalifornia kwi ii-graphene supercapacitors Inokusinika iibhetri ezitshaja ngokukhawuleza kwaye zithathe indawo encinci kakhulu.
Okufunyenweyo kuye kwenziwa kwiDyunivesithi yaseCalifornia, eLos Angeles (UCLA) kwisikolo sayo iHenry Samueli School of Engineering and Applied Sciences. Unjingalwazi uHenry Kraner uye wakhokela iprojekthi ephumelele ekudaleni i-graphene-based supercapacitors. yayo isantya sokulayisha sikhohlakeleNgokukodwa, phakathi kwekhulu kunye newaka eliphindwe ngokukhawuleza kunelo lweebhetri zangoku. Kuye kwathiwa inokuhlawulisa i-smartphone kwimizuzwana emi-5, kodwa mhlawumbi kukuzibaxa.
Njengoko besitshilo, ubungakanani bayo bukwancinci kakhulu. Ezi bhetri zinokuba ilungile ngeathom yekhabhoni. Kwaye kungenxa yokuba igraphene inalo mgangatho onobunzulu, iveliswa ngamashiti ale ngqindilili kwaye ke ngokuphandle anokwandiswa kangangoko ufuna. Ukusebenzisa olu phawu kunokwenziwa izixhobo ezibhityileyo kakhulu nezikhaphukhaphu.
Eyona nto inomdla kakhulu kukuba indlela yokuvelisa abayisebenzisileyo kwilabhoratri inokudluliselwa kuyo nayiphi na indlu. Basebenzise nje isishicileli seDVD kunye nolwelo olwenziwe ngegraphite oxide esasazwe emanzini. Baye bakwazi ukwenza i-100 micro supercapacitors kwiDVD ngaphantsi kwemizuzu engama-30.
Iqela lophando sele liqhagamshelane nabavelisi ukuba banike indawo yokuthengisa ukuze ngenye imini sijabulele le teknoloji. Le nkqubela phambili ayisebenzi kuphela kwizixhobo eziphathwayo, kodwa inokunabela nakwiimoto zombane.
Okwangoku, akunakutshiwo ukuba siza kukubona oku kungekudala kodwa kulungile ukwazi ukuba inkqubela yenziwa ekusombululeni iingxaki zobomi bokwenyani.
Umthombo: Imeyile yemihla ngemihla
Ewe into yegraphene ibonakala ingakholeleki. Kwaye ndiyathemba ukuba ayifani nomboniso bhanyabhanya oqhelekileyo abathi batyumbe ii-Oscars ze-gazillion emva koko bangaphumeleli nanye.

Ulungile. Zingaphi izihlandlo esiye saba neenkohliso zethu, kodwa kulo mbandela kukho izinto ezininzi ezinomdla ezibandakanyekayo kwaye abo bazi ngokwenene ngezi zinto kwinqanaba lobugcisa bambalwa. Iminwe yawela, kuba iibhetri zeetafile kunye nee-smartphones zininzi.
