Ku myaka 5-10 egiddako, lithium ion eya bulijjo ejja kufuga. Ennongoosereza ez’okweyongera zikuuma ebintu bya katoodi ebijja, silikoni anodes nga bikyusa graphite (obusobozi obulaga 20-40%), okulongoosa mu nkola y’okukola Okukendeeza ku nsaasaanya.
Ebisale bya bbaatule byakka ebitundu nga 90% okuva mu 2010 okutuuka mu 2023, okuva ku ddoola nga 1,100/kWh okutuuka ku ddoola 130/kWh ku bbaatule za EV. Omuze ogwo gugenda mu maaso, mpozzi n’okukuba $80-100/kWh omwaka 2030 we gunaatuukira.Ku miwendo egyo, EV zituuka ku cost parity ne gas vehicles nga tezirina ssente za ssente.
Okukendeeza ku cobalt kye kikulu ennyo. Cobalt Mining erina eddembe ly’obuntu n’obulabe bw’okugaba ebintu. Battery za NMC ez’omulembe zikozesa cobalt ntono okusinga formulations enkadde (NMC 811 erina 80% nickel, 10% manganese, 10% cobalt okusinziira ku 1:1:1 ratios ezaasooka). Battery za LFP teziriimu cobalt n’akatono.
Silicon anodes nga zitundibwa kati. Sila Nanotechnologies egaba silicon anode material eri abakola ebintu ebingi. Panasonic yalangiridde bbaatule za silicon anode okusobola okuzifulumya. Tesla nga bakozesa silicon ezimu mu butoffaali bwazo dda. Kino kitumbula obusobozi 10-20% nga tewali kintu kirala kyonna kikyusizza ku bbaatule.
Ekibuuzo "What has lithium ion batteries" kijja kuba n'eky'okuddamu ekiwanvu n'okusingawo mu myaka etaano. Ebika by'ebintu ebirala ebigenda mu maaso n'amasannyalaze. Enkola endala nga lithium ion esengula tekinologiya omukadde. Tekinologiya yakula mangu naye nga ekyatereera.
Okutegeera ebyuma ki ebikozesa bbaatule za lithium kikulu nnyo nga bwe tukung’aanya ebisingawo ku byo. Amaka agasinga kati galina ebyuma ebiddamu okucaajinga 20-50. Okumanya ky’olina, engeri y’okugikuumamu, ne ddi lw’olina okugikyusa kifuula ssente ezo okuwangaala n’okukola obulungi.
