Ka la 11 Pherekhong 2024, bafuputsi ba Harvard John A. Paulson School of Engineering and Applied Sciences United States ba ile ba fihlela katleho ka ho hlahisa beteri ea tšepe ea lithium, e ileng ea etsa hore ho be le phetoho e khōlō lefapheng la lipalangoang tsa motlakase.Betri ena ha e ithorise feela ka nako ea bophelo ea bonyane 6000 ea li-charge-dicharge cycles, e fetang libeteri leha e le life tse ling tse bonolo, empa hape e finyella ho tjhaja ka potlako ka metsotso e seng mekae feela.Tsoelopele ena ea bohlokoa e fana ka mohloli o mocha oa matla bakeng sa nts'etsopele ealithuthuthu tsa motlakase, e fokotsa haholo linako tsa ho tjhaja le ho ntlafatsa ts'ebetso ea lithuthuthu tsa motlakase bakeng sa ho tsamaea letsatsi le letsatsi.
Bafuputsi ba ile ba qaqisa mokhoa oa tlhahiso le litšobotsi tsa betri ena e ncha ea lithium-metal khatisong ea bona ea morao-rao ho "Nature Materials."Ho fapana le libeteri tse tloaelehileng tsa pakete e bonolo, betri ena e sebelisa anode ea lithium-metal mme e sebelisa electrolyte e tiileng, e bakang ts'ebetso e phahameng ea ho tjhaja le ho phela nako e telele.Sena se nolofalletsalithuthuthu tsa motlakaseho tjhaja ka potlako, ho ntlafatsa haholo boiketlo ba basebelisi.
Ka ho fihla ha betri e ncha, nako ea ho tjhaja lithuthuthu tsa motlakase e tla fokotseha haholo, e leng se tla matlafatsa boiphihlelo ba basebelisi haholo.Ho feta moo, ka lebaka la keketseho e kholo ea nako ea bophelo ba betri, mefuta ea lithuthuthu tsa motlakase e tla bona ntlafatso e hlokomelehang, e sebetsanang le mefuta e mengata ea litlhoko tsa maeto.Katleho ena ke mohato oa bohlokoahali ho khothaletsong ho ata ha lipalangoang tsa motlakase, ho fokotsa ho itšetleha ka mehloli ea khale ea matla.
Ho latela lintlha tse tsoang ho Harvard John A. Paulson School of Engineering and Applied Sciences, betri e ncha ea lithium-metal e na le nako ea ho tjhaja bonyane li-cycle tse 6000, e leng taelo ea ntlafatso ea boholo ha e bapisoa le nako ea bophelo ea libeteri tse tloaelehileng tsa pakete e bonolo.Ho feta moo, lebelo la ho tjhaja la betri e ncha le potlakile ka mokhoa o makatsang, le hloka metsotso e seng mekae feela ho qeta tefiso, ho etsa hore nako ea ho tjhaja lithuthuthu tsa motlakase e batla e se na thuso ts'ebelisong ea letsatsi le letsatsi.
