Igihugu gikomeyebateri yubushyuhe bukeerekana amashanyarazi make mumashanyarazi make.Batiri ya Litiyumu-ion yishyuza ku bushyuhe buke bizatanga ubushyuhe muri reaction ya chimique ya electrode nziza kandi mbi, bikaviramo ubushyuhe bwa electrode.Bitewe no kudahungabana kwa electrode nziza kandi mbi ku bushyuhe buke, biroroshye gutera reaction ya electrolyte kubyara umwuka mwinshi hamwe nubushyuhe bwa lithium, bityo bikangiza imikorere yamashanyarazi.Kubwibyo, ubushyuhe buke ninzira byanze bikunze mugusaza kwa bateri.
Ubushyuhe bwa batiri ya Litiyumu-ion ni buke cyane ku bushyuhe buke, bizangiza ingaruka za electrode nziza kandi mbi.Iyo ubushyuhe bwumuriro wa bateri buri munsi yubushyuhe bwicyumba, electrode nziza ya bateri irakora kandi ikangirika, kandi gaze nubushyuhe byabyaye byegeranya muri gaze ikozwe muri electrode nziza, bigatuma selile yaguka.Niba ubushyuhe buri hasi cyane mugihe cyo gusohora, inkingi zizahinduka.Kugirango ukomeze ibikorwa bya electrode mbi na electrode nziza, bateri igomba kwishyurwa ubudahwema, kubwibyo, ibikoresho byiza bya electrode byiza bigomba kubikwa mumwanya runaka bishoboka mugihe cyo kwishyuza.
Ubushobozi bwa bateri bwangirika vuba mugihe cy'ubushyuhe buke kandi bifite ingaruka zikomeye mubuzima bwa bateri.Kwishyuza ubushyuhe buke biganisha ku guhinduka kwinshi kwinshi muri electrode nziza kandi mbi, nayo iganisha ku gukora dendrite ya lithium bityo bikagira ingaruka kumikorere ya bateri.Gutakaza ingufu nubushobozi bwo kwangirika mugihe cyo kwishyuza / gusohora nabyo ni ikintu gikomeye kigira ingaruka mubuzima bwa bateri, kandi kubora kwa cathode ya LiCoSiO 2 na cathode ya LiCoSiO 2 mubushyuhe bwinshi bitanga gaze nibibyimba hamwe na electrolyte ikomeye, bigira ingaruka kuri ubuzima bwa bateri.Imyitwarire ya electrode nziza kandi mbi hamwe na electrolyte mubushyuhe buke itanga ibibyimba bihungabanya electrode nziza kandi mbi mugihe cya bateri, bityo bigatuma ubushobozi bwa bateri bwangirika vuba.
Kongera ubuzima bwikurikiranya biterwa nuburyo bwasohotse bwa bateri hamwe na lithium ion yibanda mugihe cyo kwishyuza.Ubunini bwa lithium ion buzabuza imikorere yamagare ya bateri, mugihe lithium nkeya izabuza imikorere yamagare ya bateri.Nkuko kwishyuza ku bushyuhe buke bizatera electrolyte kwitwara nabi, bityo bikagira ingaruka nziza kuri electrode nziza kandi mbi, bizatera imikoranire hagati yibintu byiza na bibi bya electrode ikora bityo bigatuma electrode mbi ikora kandi ikabyara gaze nyinshi kandi amazi, bityo byongera ubushyuhe bwa bateri.Iyo intungamubiri za lithium ion ziri munsi ya 0,05%, ubuzima bwikiziga ni inshuro 2 gusa / kumunsi;mugihe amashanyarazi ya bateri arenze 0.2 A / C, sisitemu yumuzingi irashobora kugumana inshuro 8-10 / kumunsi, mugihe iyo lithium dendrite yibanze iri munsi ya 0.05%, sisitemu yumuzingi irashobora gukomeza inshuro 6-7 / kumunsi .
Ku bushyuhe buke, gutakaza amazi bizagaragara muri electrode mbi na diaphragm ya batiri ya Li-ion, bizatuma igabanuka ryimikorere ya cycle nubushobozi bwo kwishyuza bateri;polarisiyasi yibintu byiza bya electrode nabyo bizatera ihinduka ryimiterere yibintu bibi bya electrode, bikavamo ihungabana rya lattice hamwe no kohereza amafaranga;guhumeka, guhindagurika, desorption, emulisation no kugwa kwa electrolyte nabyo bizatuma igabanuka ryimikorere ya cycle ya bateri.Muri bateri ya LFP, ibikoresho bikora hejuru ya bateri bigenda bigabanuka buhoro buhoro uko umubare wamafaranga yishyurwa nogusohoka wiyongera, kandi kugabanuka kwibikoresho bikora bizagabanya ubushobozi bwa bateri;mugihe cyo kwishyuza no gusohora, uko umubare wamafaranga yishyurwa no gusohora wiyongera, ibikoresho bikora kuri interineti byongeye guterana muburyo bukomeye kandi bwizewe, bigatuma bateri iramba kandi ifite umutekano.
