Libetri tsa lithium-ion ke e 'ngoe ea mefuta e mecha ea libeteri tse tsoetsoeng nakong ea ntlafatso ea betri.
Libetri li arotsoe ka libeteri tse omeletseng tse ka sebelisoang hang feela, "libetri tsa mantlha", le libeteri tse ka nchafatsoang le ho sebelisoa hangata, "libetri tsa bobeli". Libetri tsa lithium-ion ke libeteri tsa bobeli tse ka nchafatsoang hape. Ha ho bapisoa le mefuta e meng ea libeteri, libeteri tsa lithium-ion li ikhetha ka boholo ba tsona bo kopaneng le thepa e bobebe, e leng se etsang hore e be tse loketseng lisebelisoa tsa elektroniki tse nkehang habonolo. Ho phaella moo, ba khona ho boloka matla a mangata a motlakase, ho etsa hore e be mohloli o sebetsang oa matla.
Kamoo libetri tsa lithium-ion li hlahisang motlakase kateng
Molao-motheo oa motheo oa ho sebetsa oa libeteri o tšoana, o kenyelletsa electrode e ntle (cathode), electrode e mpe (electrode e mpe), le electrolyte. Ka hare ho betri, electrolyte e lumella li-ion hore li fete, ha li-electrone li phalla ho tloha ho electrode e mpe ho ea ho electrode e ntle, kahoo e hlahisa motlakase oa motlakase. Bakeng sa libeteri tsa bobeli, tse kang libeteri tsa lithium-ion, li ka boloka lielektrone ho electrode e mpe esale pele ka ho tjhaja, 'me ha betri e tsoa, li-electrone tsena li phallela ho electrode e ntle, kahoo e hlahisa motlakase.
Ka mor'a moo, a re shebeng litšobotsi le melemo ea libeteri tsa lithium-ion. Lebaka leo ka lona libetri tsa lithium-ion li hlahellang har'a libeteri tse ngata ke haholo-holo ka lebaka la sebopeho sa tsona se ikhethang le khetho ea thepa. Ntlha ea pele, libeteri tsa lithium-ion li sebelisa metsoako ea tšepe e nang le lithium ho electrode e ntle le carbon (e kang graphite) e ka khonang le ho boloka lithium ho electrode e mpe. Moqapi ona o lumella libeteri tsa lithium-ion ho hlahisa motlakase ntle le tlhokahalo ea ho senya li-electrode ka ho qhibiliha electrolyte joaloka libeteri tsa setso, kahoo li fokotsa ho tsofala ha betri. Taba ea bobeli, lithium ke ntho e nyane ebile e bobebe, e etsang hore libeteri tsa lithium-ion li kopane le ho ba bobebe ka matla a tšoanang. Ho phaella moo, libeteri tsa lithium-ion li boetse li na le melemo ea matla a matla a matla, bophelo ba nako e telele ea potoloho, 'me ha ho na phello ea mohopolo, kaofela ha tsona li entse libeteri tsa lithium-ion tse sebelisoang haholo lisebelisoa tsa elektronike tse nkehang, likoloi tsa motlakase le masimo a mang.
