Gukomeza gukwirakwiza ibintu byateje imbere iterambere ryihuse ryinganda za batiri.Yaba inganda nshya ziteza imbere ingufu zinganda cyangwa inganda zibika ingufu,ibikoresho byo kubika ingufuni ihuriro rikomeye.Inkomoko yamashanyarazi ishingiye kumashanyarazi ya okiside-kugabanya reaction irashobora kwirinda kugabanuka kwinzira ya Carnot kandi ifite imbaraga zo guhindura ingufu zigera kuri 80%.Nibikoresho bikwiranye cyane ninganda nini zibika ingufu.Kugeza ubu, icyifuzo cyo kunoza imikorere rusange ya batiri gikomeje kwiyongera, ariko kandi gihura ningorane nko kugabanuka kwimikorere yumubiri nubumashini, gutunganya no gukoresha neza ibiciro.
Imbaraga za chimique zabayeho ikinyejana cyo kwegeranya, kandi hashyizweho sisitemu itunganijwe iyobowe nubumenyi bwa siyansi bushobora gushakishwa.Sisitemu ikubiyemo ibice bitandukanye byibikoresho no gushyigikira ibikorwa byo gukora bigize bateri.Mugihe kizaza, hazakomeza kubaho ibihe tekinoroji ya batiri ikomeza kubana, ariko hazabaho inzira nyamukuru kandi itari iyambere.Mugihe kimwe, hazabaho ibicuruzwa bitandukanye muri sisitemu imwe kugirango ihuze ibikenewe bitandukanye.
Biragoye kugera kubikorwa byogukora ibintu byinshi munsi ya sisitemu yimashanyarazi, kandi kunoza imikorere imwe bisaba kwigomwa ikindi gikorwa.Kubwibyo, hashingiwe kubintu bikungahaye bikurikizwa kuri porogaramu, hemejwe ko sisitemu zitandukanye za batiri zizakomeza kubana igihe kirekire.Ariko bigomba kumenyekana ko kubana bidasobanura umugabane rusange ku isoko.
Guhindura imikorere bigira ingaruka kubintu byinshi, kandi icyerekezo cyingirakamaro gishobora kuba gitandukanye.Harimo ubwoko nigipimo cyibikoresho byiza nibibi, kimwe nigishushanyo mbonera nigikorwa cyo gukora, bizagira ingaruka kumubyigano wingufu nigipimo cyibikorwa bya bateri, bivuze ko niba icyerekezo cyingaruka zitandukanye, imikorere ntizahuza.Kurugero, muribateri ya lithium-ion, firime ya SEI yakozwe hagati yibikoresho bya electrode na electrolyte kumurongo ukomeye-wamazi irashobora kwemeza kwinjiza no gukuramo Li + kandi icyarimwe ikingira electron.Ariko, nka firime ya passivation, ikwirakwizwa rya Li + rizaba rito, kandi film ya SEI izavugururwa.Bizatera igihombo gihoraho cya Li + na electrolyte, hanyuma bigabanye ubushobozi bwa bateri.
Intambara yikoranabuhanga murwego rwubushobozi buhanitse igena icyerekezo cyicyitegererezo.Isoko rinini rifite ubushobozi risobanura umugabane munini.Kubwibyo, niba ubwoko runaka bwa sisitemu bwujuje neza ibikenewe ku isoko rinini cyane, kwinjiza ibicuruzwa bizamura umugabane wa sisitemu.Ibisabwa bikenewe kugirango ingufu zingana muriamashanyarazibashoboje sisitemu ya bateri ifite ingufu zidasanzwe zo guhagarara no gusimbuza izindi sisitemu.
