Libetri li ka aroloa ka mekhahlelo e meraro ka bophara: libetri tsa lik'hemik'hale, libetri tsa 'mele le libetri tsa baeloji. Libetri tsa lik'hemik'hale ke tsona tse sebelisoang haholo likoloing tsa motlakase.
Betri ea lik'hemik'hale: Betri ea lik'hemik'hale ke sesebelisoa se fetolang matla a lik'hemik'hale hore e be matla a motlakase ka lik'hemik'hale. E na le li-electrode tse ntle le tse mpe le li-electrolyte.
Betri ea 'mele: Betri ea 'mele e fetola matla a 'mele (joalo ka matla a letsatsi le matla a mechini) hore e be matla a motlakase ka liphetoho tsa 'mele.
Sehlopha sa dibetri tsa dikhemikhale: Ho ya ka pono ya sebopeho, e ka arolwa ka mekhahlelo e mmedi: dibetri tsa polokelo (ho kenyeletswa le dibetri tsa mantlha le dibetri tsa bobedi) le disele tsa mafura. Dibetri tsa mantlha: di ka sebediswa hanngwe feela, thepa e sebetsang ha e ka ke ya kgutliswa, ho itshunya ha yona ho nyane, khanyetso ya kahare e kgolo, mme bokgoni bo ikgethang ba boima le bokgoni bo ikgethang ba bophahamo di hodimo.
Libetri tsa bobeli: li ka tjhajwa le ho ntshwa kgafetsa, thepa e sebetsang e ka kgutlisetswa morao, mme di sebediswa haholo disebedisweng tse fapaneng tsa ho tjhaja. Bongata ba mehlala e mmarakeng hajwale e sebedisa dibetri tse tjhajwang hape tsa bobedi ho kganna koloi. Libetri tsa bobedi di arotsoe ka dibetri tsa lead-acid, dibetri tsa nickel-cadmium, dibetri tsa nickel-metal hydride le dibetri tsa lithium ho ya ka disebediswa tse fapaneng tse ntle tsa electrode. Hona jwale, dikhamphani tsa dikoloi tse mmarakeng di sebedisa haholo dibetri tsa lithium, mme tse mmalwa di sebedisa dibetri tsa nickel-metal hydride.
Tlhaloso ea betri ea lithium
Betri ea Lithium ke betri e sebelisang tšepe ea lithium kapa motsoako oa lithium e le thepa ea electrode e ntle kapa e mpe le tharollo ea electrolyte e seng metsi.
Ts'ebetso ea ho tjhaja le ho ntsha betri ea lithium e itšetlehile haholo-holo ka motsamao oa li-ion tsa lithium (Li+) lipakeng tsa li-electrode tse ntle le tse mpe. Ha ho tjhaja, li-ion tsa lithium lia tlosoa ho tloha ho electrode e ntle ebe li kenngoa ka har'a electrode e mpe ka har'a electrolyte, 'me electrode e mpe e boemong bo ruileng ba lithium; se fapaneng ke 'nete ha ho tjhaja.

Libetri tsa lithium-ion li na le matla a mangata, li phela nako e telele ebile li khona ho intša ka botsona, 'me li sebelisoa haholo lifonong tsa thekeng, lilaptop le likoloing tsa motlakase.
Masimo a tshebediso ya dibetri tsa lithium-ion a arotsoe haholo ka matla le a sa sebeliseng motlakase. Masimo a motlakase a tshebediso ya dibetri tsa lithium-ion a kenyeletsa dikoloi tsa motlakase, disebediswa tsa motlakase, jj.; masimo a sa sebediseng motlakase a kenyeletsa disebediswa tsa elektroniki tsa bareki le masimo a polokelo ya matla, jj.
Sebopeho le ho hlopha libeteri tsa lithium
Libetri tsa Lithium-ion li entsoe haholo-holo ka likarolo tse 'ne: thepa ea electrode e ntle, thepa ea electrode e mpe, li-electrolyte le baaroli ba betri. Lisebelisoa tsa electrode e mpe li ama haholo-holo katleho ea pele le ts'ebetso ea potoloho ea libeteri tsa lithium-ion. Li-electrode tse mpe tsa betri ea Lithium li arotsoe haholo ka mekhahlelo e 'meli: thepa ea carbon le thepa e seng ea carbon. Tšebeliso e shebaneng haholo le 'maraka ke thepa ea electrode e mpe ea graphite har'a thepa ea carbon, eo har'a eona graphite ea maiketsetso le graphite ea tlhaho li nang le lits'ebetso tse kholo tsa indasteri. Li-electrode tse mpe tse thehiloeng ho silicon ke sepheo sa lipatlisiso ke bahlahisi ba li-electrode tse kholo tse mpe 'me ke e' ngoe ea thepa e ncha ea electrode e mpe e ka sebelisoang haholo nakong e tlang.
Libetri tsa lithium-ion li arotsoe ka libeteri tsa lithium cobalt oxide, libeteri tsa lithium iron phosphate, libeteri tsa ternary, jj. ho latela thepa e ntle ea electrode;
Ho ya ka mofuta wa sehlahiswa, di arotswe ka dibetri tse sekwere, dibetri tse silindara le dibetri tse bonolo;
Ho ea ka maemo a ts'ebeliso, li ka aroloa ka lisebelisoa tsa elektroniki tsa bareki, polokelo ea matla le libeteri tsa motlakase. Har'a tsona, libeteri tsa lithium tsa bareki li sebelisoa haholo-holo lihlahisoa tsa 3C; libeteri tsa polokelo ea matla li sebelisoa haholo-holo polokelong ea matla ea malapa le polokelong ea matla ea sistimi ea motlakase e ikemetseng e ajoang joalo ka matla a letsatsi le tlhahiso ea matla a moea; libeteri tsa motlakase li sebelisoa haholo-holo likoloing tse fapaneng tsa motlakase, lisebelisoa tsa motlakase le likoloi tse ncha tsa matla.
