Ni iki mu by'ukuri kigena ubuziranenge bw'ipamba mu gukora bateri za Lithium?

Mu gukora bateri za lithium-ion, gusiga si intambwe y'ibikorwa gusa - ni ikintu cy'ingenzi kigena imikorere ya bateri, imiterere ihamye, n'imikorere myiza. Kuva kuri bateri z'amashanyarazi za EV kugeza kuri sisitemu nini zo kubika ingufu, abakora barushaho kugira igitutu cyo kugera ku buhanga bwo hejuru, ubushobozi bwo gukora vuba, no kugabanya ubusembwa.

Ariko, ibibazo bisanzwe biracyagoye kubikemura:

• Kudasigana neza bitera ubushobozi budahamye no kugabanuka k'igihe cyo gukora imyitozo ngororamubiri.

• Gutakaza amazi no kudahuza kw'ubucucike bigira ingaruka ku bwiza bwa electrode

• Umuvuduko gakondo wo gusiga 80–100 m/umunota kugabanya umusaruro munini

• Kumira bitera inenge nko kugorama no gucikagurika kw'inkombe

Uko umusaruro ugenda uzamuka ugana ku rwego rw'inganda nini, ibi bibazo ntibikiri ibibazo byihariye - bigira ingaruka zitaziguye ku musaruro, ikiguzi, no ku ihangana.

Kugira ngo ibyo bibazo bikemuke, ikoranabuhanga rigezweho ryo gusiga irangi riri kuba ingenzi cyane. By'umwihariko, sisitemu zo gutwikira zikoresha uburyo bwo gutwikira bwihuse bubiri birushaho gukoreshwa mu nganda zigezweho zo gukora bateri.

Ugereranije n'ibikorwa bisanzwe, izi sisitemu zishobora:

• Kunoza imikorere muri rusange binyuze mu 60–80%

• Kugera ku muvuduko wo gusiga kugeza ku 160 m/umunota

• Komeza gukora neza cyane ukoresheje uburyo bwo kugenzura ko ibintu bihinduka mu gihe ± 1.0%

• Menya neza ko umutekano uhoraho mu gihe ± 2N

• Gutanga umusaruro uhoraho wo kumisha hamwe n'ihindagurika ry'umwuka ≤ ± 2%

Icy'ingenzi kurushaho, uburyo bwo gusiga buhuriweho buhuza gusiga, kumisha, no kuzunguruka mu buryo buhoraho kandi bwikora - bigabanya cyane uburyo bwo gukoresha intoki no kunoza umuvuduko w'umusaruro.

Mu bikorwa nyabyo, abakora ibikorwa byo kuvugurura uburyo bwo gusiga irangi ku mpande ebyiri batangaje ko imikorere yabo yazamutse ku rugero rurenga 30%, hamwe no kugabanuka kw'ibipimo by'ubusembwa n'imyanda y'ibikoresho. Izi ntambwe ni ingenzi cyane cyane mu bidukikije bikorerwamo umusaruro mwinshi aho n'impinduka nto zishobora gutera igihombo gikomeye.

Ku bakora bashaka ibisubizo byizewe, ikoranabuhanga rihuriweho ryo gusiga irangi ryakozwe n'abatanga ibikoresho bafite uburambe nka Pengjin zikoreshwa cyane haba mu mishinga yo kubika bateri z'amashanyarazi ndetse no mu mishinga yo kubika ingufu. Izi sisitemu zagenewe gucunga ibikoresho bito cyane (urugero, urupapuro rw'umuringa rwa 4μm n'urupapuro rwa aluminiyumu rwa 6μm) mu gihe ikomeza gukora neza kandi yihuta cyane.

Uretse ibikoresho byigenga, imashini zigezweho zo gusiga amarangi zigenda zishyirwa mu mikorere yuzuye, zikorana na sisitemu zo gusana za NMP, kuzizungurutsa no kuzikata kugira ngo habeho sisitemu yuzuye y’ubuhanga mu gukora.

Uko inganda za bateri za lithiamu zikomeza gutera imbere, ikoranabuhanga ryo gusiga irangi ntabwo rikiri iry’ikoreshwa ry’ibikoresho gusa - ahubwo rigamije gutuma umusaruro urushaho kwaguka, ufite ireme ryo hejuru, kandi uhendutse.

Niba uteganya umurongo mushya wo gukora bateri cyangwa kunoza usanzweho, gusobanukirwa uburyo sisitemu zigezweho zo gusiga amarangi zinoza imikorere n'uburyo zihoraho bishobora kugira itandukaniro rigaragara mu musaruro wawe.
