Libetri tsa koloi ea motlakase ke karolo e le 'ngoe e turang ka ho fetisisa koloing ea motlakase.
Theko ea eona e holimo e bolela hore likoloi tsa motlakase li theko e boima ho feta mefuta e meng ea mafura, e leng se liehisang ho sebelisoa ha likoloi tsa motlakase tse ngata.
Lithium-ion
Libetri tsa lithium-ion ke tsona tse tsebahalang haholo. Ntle le ho hlalosa ka botlalo, li ntša le ho tjhaja hape kaha electrolyte e jara li-ion tsa lithium tse chariloeng hantle ho tloha anode ho ea cathode, le ka tsela e fapaneng. Leha ho le joalo, thepa e sebelisoang ka har'a cathode e ka fapana pakeng tsa libeteri tsa lithium-ion.
LFP, NMC, le NCA ke dikhemistri tse tharo tse fapaneng tsa dibetri tsa Lithium-ion. LFP e sebedisa Lithium-phosphate e le thepa ya cathode; NMC e sebedisa Lithium, Manganese, le Cobalt; mme NCA e sebedisa Nickel, Cobalt le Aluminium.
Melemo ea libeteri tsa Lithium-ion:
● Libetri tsa NMC le NCA li theko e tlase ho li hlahisa.
● Nako e telele ea bophelo – e fana ka lipotoloho tse 2,500-3,000 tsa ho tjhaja/ho ntsha motlakase ka botlalo ha ho bapisoa le tse 1,000 bakeng sa libeteri tsa NMC.
● Hlahisa mocheso o fokolang ha o ntse o tjhaja e le hore e ka kgona ho boloka sekgahla se phahameng sa matla nako e telele ka hara mothapo wa tjhaja, e leng se lebisang ho tjhajeng kapele ntle le tshenyo ya betri.
● E ka tjhajwa ho fihlela ho 100% ka tshenyo e nyane ya betri kaha e thusa ho lekanya betri le ho fana ka dikhakanyo tse nepahetseng haholoanyane tsa sebaka - Beng ba mohlala wa 3 ba nang le betri ya LFP ba eletswa ho boloka moedi wa tjhaja o beilwe ho 100%.
Selemong se fetileng, Tesla e ile ea fa bareki ba eona ba Model 3 Amerika khetho pakeng tsa betri ea NCA kapa ea LFP. Betri ea NCA e ne e le bobebe ba 117kg 'me e ne e fana ka sebaka se selelele ho feta sa lik'hilomithara tse 10, empa e ne e e-na le nako e telele haholo ea ho etella pele. Leha ho le joalo, Tesla e boetse e khothaletsa hore mofuta oa betri ea NCA o tjhaje feela ho fihlela ho 90% ea bokhoni ba eona. Ka mantsoe a mang, haeba u rera ho sebelisa sebaka se felletseng khafetsa, LFP e ntse e ka ba khetho e betere.
Hydride ea tšepe ea nikeli
Libetri tsa hydride tsa nickel-metal (tse khutsufalitsoeng ho NiMH) ke tsona feela tse ka sebelisoang ho fapana le libeteri tsa lithium-ion tse fumanehang 'marakeng hona joale, leha hangata li fumanoa likoloing tsa motlakase tse kopantsoeng (haholo-holo Toyota) ho fapana le likoloi tsa motlakase tse hloekileng.
Lebaka le ka sehloohong la sena ke hore bongata ba matla a libeteri tsa NiMH bo ka tlase ho 40% ho feta libeteri tsa lithium-ion.
