I-Revolutionary Solid-State Battery Propels Ukushaja Okusheshayo kwezithuthuthu zikagesi

NgoJanuwari 11, 2024, abacwaningi base-Harvard John A. Paulson School of Engineering and Applied Sciences e-United States bathola impumelelo ngokwakha inoveli yebhethri ye-lithium-metal, eyabangela uguquko oluguquguqukayo emkhakheni wezokuthutha ngogesi.Leli bhethri aligcini nje ngokuziqhayisa ngeminyaka yokuphila okungenani yemijikelezo yokushaja engu-6000, lidlula noma yimaphi amanye amabhethri ephakethe elithambile, kodwa futhi lifinyelela ukushajwa okusheshayo emizuzwini embalwa nje.Le ntuthuko ebalulekile ihlinzeka ngomthombo wamandla omusha wokuthuthukiswa kweizithuthuthu zikagesi, kunciphisa kakhulu izikhathi zokushaja nokuthuthukisa ukusebenza kwezithuthuthu zikagesi ekuhambeni kwansuku zonke.

Abacwaningi bachaze kabanzi indlela yokukhiqiza nezici zaleli bhethri elisha le-lithium-metal ekushicilelweni kwabo kwakamuva kokuthi "Izinto Zemvelo."Ngokungafani namabhethri ephakethe elithambile lendabuko, leli bhethri lisebenzisa i-lithium-metal anode futhi lisebenzisa i-electrolyte yesimo esiqinile, okuholela ekusebenzeni kahle kokushaja kanye nokuphila okunwetshiwe.Lokhu kunika amandlaizithuthuthu zikagesiukushaja ngokushesha, ukuthuthukisa kakhulu ukusebenziseka kalula kubasebenzisi.

Ngokufika kwebhethri elisha, izikhathi zokushajwa kwezithuthuthu zikagesi zizoncishiswa kakhulu, okuzothuthukisa kakhulu ulwazi lomsebenzisi.Ngaphezu kwalokho, ngenxa yokwanda okukhulu kwesikhathi sokuphila kwebhethri, ibanga lezithuthuthu zikagesi lizobona ukuthuthuka okubonakalayo, okuhlinzekela uhla olubanzi lwezidingo zokuhamba.Lokhu kuphumelela kuyingqopha-mlando ekukhuthazeni ukwamukelwa kabanzi kwezinto zokuthutha ngogesi, ukunciphisa ukuncika emithonjeni yamandla evamile.

Ngokusho kwedatha evela ku-Harvard John A. Paulson School of Engineering and Applied Sciences, ibhethri elisha le-lithium-metal linomjikelezo wokuphila womjikelezo wokushaja okungenani imijikelezo engu-6000, ukuhleleka kokuthuthukiswa kobukhulu uma kuqhathaniswa nesikhathi sokuphila samabhethri ephakethe elithambile.Ngaphezu kwalokho, ijubane lokushaja lebhethri elisha lishesha ngokumangalisayo, lidinga imizuzu embalwa kuphela ukuqedela ukushaja, okwenza isikhathi sokushaja sezithuthuthu zikagesi sicishe singabi nandaba ekusetshenzisweni kwansuku zonke.

Lokhu kutholakala kwesisekelo kuzovula amathuba amasha okusetshenziswa okusabalele kweizithuthuthu zikagesi.Ngokuthuthuka okuqhubekayo kobuchwepheshe obusha bebhethri, ezokuthutha ngogesi zingena enkathini esebenza kahle futhi elula.Lokhu futhi kunikeza isiqondiso kubakhiqizi bezithuthuthu zikagesi, bebanxusa ukuthi bakhulise utshalomali ocwaningweni nasekuthuthukisweni kobuchwepheshe obusha bamandla, kusheshiswe inguquko eluhlaza kwezokuthutha ngogesi.
