Lilemong tsa morao tjena, libeteri tsa lithium-ion li hlahile e le theknoloji ea bohlokoa phetohong e lebisang mehloling ea matla a tsosolositsoeng le likoloi tsa motlakase (EVs). Tlhokahalo e ntseng e eketseha ea libeteri tse sebetsang hantle le tse theko e tlaase e khothalelitse tsoelo-pele e kholo tšimong. Selemong sena, litsebi li bolela esale pele lintlafatso tse 'maloa tse ka fetolang bokhoni ba libeteri tsa lithium-ion.
Khatelo-pele e 'ngoe e hlokomelehang eo u lokelang ho e ela hloko ke nts'etsopele ea li-betri tse tiileng. Ho fapana le libeteri tsa khale tsa lithium-ion tse sebelisang li-electrolyte tsa metsi, libeteri tsa boemo bo tiileng li sebelisa lisebelisoa tse tiileng kapa li-ceramics joalo ka li-electrolyte. Mokhoa ona o mocha ha o eketse matla a motlakase feela, o ka eketsang mefuta e mengata ea li-EV, empa hape o fokotsa nako ea ho tjhaja le ho ntlafatsa polokeho ka ho fokotsa kotsi ea mollo. Likhamphani tse hlahelletseng joalo ka Quantumscape li tsepamisitse maikutlo ho li-betri tsa tšepe tsa lithium-metal, tse ikemiselitseng ho li kopanya le likoloi ho tloha ka 2025[1].
Le ha libeteri tsa boemo bo tiileng li na le ts'episo e kholo, bafuputsi ba ntse ba hlahloba lik'hemik'hale tse ling ho sebetsana le matšoenyeho mabapi le boteng ba lisebelisoa tsa bohlokoa tsa betri joalo ka cobalt le lithium. Takatso ea likhetho tse theko e tlaase, tse tšoarellang ho feta e ntse e tsoela pele ho khanna boqapi. Ho feta moo, litsi tsa thuto le lik'hamphani lefatšeng ka bophara li sebetsa ka thata ho ntlafatsa ts'ebetso ea betri, ho eketsa bokhoni, ho potlakisa lebelo la ho tjhaja, le ho fokotsa litšenyehelo tsa tlhahiso[1].
Boiteko ba ho ntlafatsa libeteri tsa lithium-ion bo fetela ka nģ'ane ho likoloi tsa motlakase. Libetri tsena li fumana lits'ebetso polokelong ea motlakase oa grid-level, e lumellang khokahanyo e ntle ea mehloli ea motlakase e nchafalitsoeng joalo ka matla a letsatsi le a moea. Ka ho sebelisa libeteri tsa lithium-ion bakeng sa polokelo ea marang-rang, botsitso le ts'epahalo ea lisebelisoa tsa matla a tsosolositsoeng li ntlafatsoa haholo[1].
Ka katleho ea morao-rao, bo-rasaense ba Lawrence Berkeley National Laboratory ba thehile seaparo sa polymer se bitsoang HOS-PFM. Ho roala hona ho nolofalletsa libeteri tsa lithium-ion tsa nako e telele, tse matla haholoanyane bakeng sa likoloi tsa motlakase. HOS-PFM ka nako e ts'oanang e tsamaisa lielektrone le li-ion ka bobeli, e matlafatsa botsitso ba betri, litefiso tsa tefiso / ho tsoa, le nako ea bophelo ka kakaretso. E boetse e sebetsa e le sekhomaretsi, se ka eketsang bophelo bo tloaelehileng ba libeteri tsa lithium-ion ho tloha ho lilemo tse 10 ho isa ho tse 15. Ho feta moo, ho roala ho bonts'itse ts'ebetso e ikhethang ha e sebelisoa ho silicon le li-electrode tsa aluminium, ho fokotsa ho senyeha ha tsona le ho boloka matla a betri a phahameng ho feta lipotoloho tse ngata. Liphuputso tsena li na le ts'episo ea ho eketsa matla a matla a betri ea lithium-ion, ho etsa hore e be theko e tlaase le ho fumaneha habonolo bakeng sa likoloi tsa motlakase[3].
Ha lefats'e le ntse le leka ho fokotsa ho tsoa ha likhase tse futhumatsang lefatše le ho fetela bokamosong bo tsitsitseng, tsoelo-pele ea theknoloji ea betri ea lithium-ion e bapala karolo ea bohlokoa. Boiteko bo tsoelang pele ba lipatlisiso le nts'etsopele bo khannela indasteri pele, bo re atametsa haufi le litharollo tsa betri tse sebetsang hantle, tse theko e tlaase, le tse baballang tikoloho. Ka katleho ea libeteri tsa boemo bo tiileng, lik'hemik'hale tse ling, le liphahlo tse kang HOS-PFM, monyetla oa ho amoheloa ha likoloi tsa motlakase le ho boloka matla a marang-rang o ntse o eketseha.
