Ubuzima bwa bateri ya lithium ni ubuhe?
Ukuzengurukaubuzima
Ubuzima bwikizamini nikintu cyingenzi mugusuzuma tekinike - imikorere yubukungu ya bateri. Inzira imwe nogusohora byitwa cycle cyangwa igihe. Mugihe cyateganijwe cyo gusohora, umubare wizunguruko bateri irashobora kwihanganira mbere yuko ubushobozi bwayo bugabanuka kugiciro cyiswe ubuzima bwikigihe cyangwa ubuzima bwa serivisi.
Ubuzima bwikizunguruka bugira ingaruka kuri Batiri yimbitse yo gusohora (DOD), kubwibyo, imvugo yubuzima bwikiziga igomba no kwerekana DOD. Kurugero, ubuzima bwa bateri yubuzima bwa cycle 400/100% DOD cyangwa 1000 cycle / 50% DOD. Ubuzima bwikizunguruka buratandukanye muburyo butandukanye bwa bateri, ndetse nibicuruzwa byuruhererekane rumwe nibisobanuro birashobora kugira ubuzima bwinzira zitandukanye. Muri bateri zikunze gukoreshwa, bateri ya zinc - ifeza zifite ubuzima bwigihe gito, muri rusange 30 - 100; kuyobora - bateri ya aside ifite ubuzima bwikurikiranya bwa 300-500; na bateri ya lithium-ion ifite igihe kirekire cyo gukora, hamwe nubuzima bwikirenga burenga 1000.
Hamwe no kwiyongera kwishyurwa no gusohora, kwangirika kwubushobozi bwa batiri ya kabiri ni inzira byanze bikunze. Ni ukubera ko mugihe cyo kwishyuza - gusohora ibintu, inzira zimwe zidasubirwaho zibaho imbere muri bateri, bigatuma igabanuka ryubushobozi bwa batiri. Ibi bintu bidasubirwaho ni nkibi bikurikira:
1) Ubuso bukora bwa electrode bugabanuka ubudahwema mugihe cyo kwishyuza - gusohora, biganisha ku kwiyongera kwubucucike bwimikorere ya polarisiyasi.
2) Ibikoresho bifatika bitandukanya cyangwa bimuka muri electrode.
3) Bimwe mubikoresho bya electrode byangirika mugihe cya bateri.
4) Dendrite ikora kuri electrode mugihe cyamagare, itera micro - imiyoboro migufi muri bateri.
5) Gusaza no kwambara bitandukanya.
6) Impinduka zidasubirwaho za kirisiti ya morfologiya ibaho mubintu bifatika mugihe cyo kwishyuza - gusohora, bityo bikagabanya ibikorwa byayo.
Ububiko
Batteri yiboneye ubushobozi nyuma yo kubika igihe kirekire; ibi biranga bizwi nkibikorwa byo kubika. Nubwo nta mbaraga z'amashanyarazi zirekurwa mugihe cyo kubika, kwikorera - gusohora buri gihe bibaho muri bateri. Ndetse no mububiko bwumye, gufunga bidahagije birashobora gutuma amazi, umwuka, na karuboni ya dioxyde yinjira, bigatera kwangirika kwibikoresho bikora bya termodinamike bidahindagurika kuri electrode nziza kandi mbi, biganisha kuri okiside - kugabanuka no gutakaza ingufu. Ibi biragaragara cyane mububiko butose. Ubunini bwibi bisohoka - bisohoka bigaragazwa nkigihe bifata kugirango ubushobozi bwa bateri bugabanuke mubushobozi runaka, buzwi nkubuzima bwo kubika (cyangwa ubuzima bwubuzima).
