Likoloi tsa motlakase (li-EV) li fumane botumo bo potlakileng lilemong tsa morao tjena e le mokhoa o hloekileng le o tsitsitseng haholoanyane ho feta likoloi tsa enjene ea motlakase ea ka hare. Ntho ea bohlokoa katlehong ea likoloi tsena ke tsoelo-pele ea theknoloji ea betri, e bileng le nts'etsopele e kholo ho ntlafatsa bokhoni, sebaka le theko e tlase.
Mofuta o tloaelehileng haholo oa betri o sebelisoang likoloing tsa motlakase ke betri ea lithium-ion. Libetri tsena li na le melemo e 'maloa, ho kenyeletsoa le matla a mangata, ho itšehla thajana ho fokolang, le bophelo bo bolelele. Leha ho le joalo, li boetse li na le meeli, joalo ka litšenyehelo tse phahameng le ho fumaneha ho fokolang ha thepa e tala.
Ho hlola liphephetso tsena, bafuputsi le bahlahisi ba ntse ba hlahloba mekhoa e fapaneng ea ho ntlafatsa libeteri tsa lithium-ion. Mokhoa o mong o joalo ke nts'etsopele ea libeteri tsa solid-state, tse sebelisang electrolyte e tiileng ho fapana le electrolyte e metsi e fumanoang libetering tsa setso tsa lithium-ion. Libeteri tsa solid-state li fana ka matla a mangata, polokeho e ntlafetseng, le bophelo bo bolelele ha li bapisoa le libeteri tse tloaelehileng.
Ntlafatso e 'ngoe e tšepisang ke tšebeliso ea li-anode tsa silicon libetering tsa lithium-ion. Silicon e na le matla a mangata haholo ho feta graphite, e sebelisoang hangata ho li-anode tsa betri ea lithium-ion. Leha ho le joalo, silicon e atisa ho atoloha le ho honyela nakong ea ho tjhaja le ho ntša tjhaja, e leng se lebisang ho senyeha ha nako e ntse e ea. Bafuputsi ba ntse ba sebetsa ka litsela tsa ho fokotsa bothata bona, joalo ka ho sebelisa li-nanoparticle tsa silicon kapa ho kenyelletsa lisebelisoa tse ling sebopehong sa anode.
Ka nqane ho libeteri tsa lithium-ion, mahlale a mang a libeteri a ntse a hlahlojoa bakeng sa tšebeliso likoloing tsa motlakase. Mohlala o mong ke tšebeliso ea libeteri tsa lithium-sulfur, tse nang le bokhoni ba ho fana ka matla a mangata ho feta libeteri tsa lithium-ion. Leha ho le joalo, libeteri tsa lithium-sulfur li tobane le liphephetso tse kang bophelo bo tlase ba potoloho le ho se sebetse hantle ha motlakase, tse hlokang ho rarolloa pele li ka sebelisoa haholo ho li-EV.
Ntle le ho ntlafatsa theknoloji ea libeteri, boiteko bo ntse bo tsoela pele ba ho nts'etsapele mekhoa e sebetsang hantle le e tsitsitseng ea ho etsa libeteri. Sena se kenyelletsa ho sebelisa thepa e sebelisitsoeng hape le ho fokotsa tšusumetso ea tikoloho ea tlhahiso ea libeteri.
Ka kakaretso, bokamoso ba theknoloji ea libeteri tsa likoloi tsa motlakase bo shebahala bo tšepisa, ka lipatlisiso le nts'etsopele tse tsoelang pele tse reretsoeng ho ntlafatsa ts'ebetso, ho fokotsa litšenyehelo le ho eketsa botsitso. Ha tsoelo-pele ena e ntse e tsoela pele, re ka lebella hore likoloi tsa motlakase li be tse khahlang le tse fumanehang habonolo ho bareki, li khanna phetoho ho ea tsamaisong ea lipalangoang e hloekileng le e tala.
Haeba o batla ho tseba haholoanyane ka sena, ka kopo ikutloe u lokolohile ho ikopanya le rona.
