Ho thehoa ha libeteri tsa lithium
Pale ealibeteri tsa lithiume qalile lilemong tsa bo-1970, ha bafuputsi ba qala ho hlahloba bokhoni ba lithium e le motsoako oa bohlokoa libetering tse ka tjhajwang hape. Ke nakong ena moo bo-rasaense ba ileng ba sibolla litšobotsi tse ikhethang tsa lithium, ho kenyeletsoa le matla a eona a mangata le tlhaho ea eona e bobebe, e leng se ileng sa etsa hore e be e loketseng lisebelisoa tsa elektroniki tse nkehang habobebe. Tšibollo ena e thehile motheo oa nts'etsopele ea libeteri tsa lithium-ion, tse tla tsoela pele ho busa 'maraka oa lisebelisoa tsa elektroniki tsa bareki ka lilemo tse tlang.
Ka 1979, setsebi sa k'hemistri sa Univesithi ea Oxford, John Goodenough, le sehlopha sa hae, ba ile ba etsa tsoelo-pele 'me ba hlahisa betri ea pele e ka nchafatsoang ea lithium-ion. Mosebetsi ona oa bo-pula-maliboho o ile oa theha motheo oa ho rekisoa ha libeteri tsa lithium-ion, tse ntseng li tuma ka potlako ka lebaka la ts'ebetso ea tsona e phahameng le bophelo bo bolelele ba ts'ebeletso ha li bapisoa le libeteri tsa setso tsa lead-acid le nickel-cadmium.
Ho pholletsa le dilemo tsa bo-1980 le bo-1990, boiteko bo boholo ba dipatlisiso le ntshetsopele bo ne bo shebane le ho ntlafatsa tshebetso le polokeho ya dibeteri tsa lithium. E nngwe ya diphephetso tsa bohlokwa ke ho fumana electrolyte e tsitsitseng e ka mamellang bongata bo phahameng ba matla a lithium ntle le ho beha polokeho kotsing. Sena se lebisitse ntshetsopeleng ya diforomo tse fapaneng tsa electrolyte le ditsamaiso tsa taolo ya betri tse ntlafatsang haholo botshepehi le polokeho ya dibeteri tsa lithium-ion.

Histori ea libeteri tsa lithium e bontša ho phehella ho sa khaotseng boqapi le matla a phetoho a theknoloji. Kajeno, libeteri tsa lithium ke lejoe la motheo la phetoho ea matla a hloekileng, e leng se nolofalletsang ho amoheloa ha likoloi tsa motlakase ka bophara le ho kopanngoa ha matla a nchafatsoang.

Ha re akaretsa, nalane ea nts'etsopele ealibeteri tsa lithiumke leeto le ikhethang la ho sibolla saense, boqapi ba theknoloji le phetoho ea indasteri. Ho tloha matsatsing a bona a pele e le lintho tse makatsang tsa laboratori ho fihlela boemong ba bona ba hona joale e le litharollo tsa polokelo ea matla tse fumanehang hohle, libeteri tsa lithium li tsamaile nako e telele ho fehleng matla lefatšeng la sejoale-joale. Ha re ntse re tsoela pele ho notlolla bokhoni bo felletseng ba libeteri tsa lithium, re tla tlisa nako e ncha ea polokelo ea matla e hloekileng, e tšepahalang le e tsitsitseng e tla bopa bokamoso ba polanete ea rona.
