Libetri tsa koloi ea motlakase ke karolo e le 'ngoe e theko e boima ka ho fetisisa koloing ea motlakase.
Theko ea theko e phahameng e bolela hore likoloi tsa motlakase li theko e boima ho feta mefuta e meng ea mafura, e leng ho fokotsang ho nkeloa ha EV ka bongata.
Lithium-ion
Libetri tsa lithium-ion ke tsona tse tsebahalang haholo. Ntle le ho kena lintlha tse ngata haholo, ba ntša le ho nchafatsa ha electrolyte e nka li-ion tsa lithium tse nang le qoso e ntle ho tloha ho anode ho ea ho cathode, le ka tsela e fapaneng. Leha ho le joalo, lisebelisoa tse sebelisoang ka cathode li ka fapana pakeng tsa libeteri tsa lithium-ion.
LFP, NMC, le NCA ke lik'hemik'hale tse tharo tse fapaneng tsa libeteri tsa Lithium-ion. LFP e sebelisa Lithium-phosphate e le thepa ea cathode; NMC e sebelisa Lithium, Manganese, le Cobalt; 'me NCA e sebelisa Nickel, Cobalt le Aluminium.
Melemo ea libeteri tsa Lithium-ion:
● Ho hlahisa libethe tse theko e tlaase ho feta libeteri tsa NMC le NCA.
● Nako e telele ea bophelo - fana ka li-cycle tse 2,500-3,000 tse feletseng tsa tefiso / ho ntša ha ho bapisoa le 1,000 bakeng sa libeteri tsa NMC.
● Hlahisa mocheso o fokolang ha o tjhaja hore o kgone ho boloka matla a phahameng halelele ho tjhaja curve, e leng se lebisang ho tjhaja kapele ntle le ho senyeha ha betri.
● E ka lefisoa ho 100% ka tšenyo e nyenyane ea betri kaha e thusa ho lekanya betri le ho fana ka likhakanyo tse nepahetseng haholoanyane tsa mefuta-futa - Beng ba Model 3 ba nang le betri ea LFP ba eletsoa ho boloka moeli oa tefiso o behiloe ho 100%.
Selemong se fetileng, Tesla e hlile e file bareki ba eona ba Model 3 ba Amerika khetho pakeng tsa NCA kapa betri ea LFP. Betri ea NCA e ne e le bobebe ba 117kg 'me e fana ka sebaka sa lik'hilomithara tse 10, empa e ne e e-na le nako e telele ea ho etella pele. Leha ho le joalo, Tesla e boetse e khothaletsa hore mofuta oa betri oa NCA o lefelloe feela ho 90% ea matla a eona. Ka mantsoe a mang, haeba u rera ho sebelisa mefuta e felletseng khafetsa, LFP e ntse e ka ba khetho e ntle.
Nickel-metal hydride
Libetri tsa nickel-metal hydride (tse khutsufalitsoeng ho NiMH) ke tsona feela tse ling tsa sebele tsa libeteri tsa lithium-ion tse ntseng li le teng 'marakeng, le hoja hangata li fumanoa likoloing tsa motlakase tse nyalisitsoeng (haholo-holo Toyota) ho fapana le likoloi tse hloekileng tsa motlakase.
Lebaka le ka sehloohong la sena ke hore matla a matla a betri ea NiMH a ka tlase ho 40% ho feta libeteri tsa lithium-ion.
