Ni izihe nyungu za bateri izuba LiFePo4?

Ibigize izubaLiFePo4bateri Umwihariko waizuba rya LiFePo4. muburyo bwibisobanuro, ni ukuvuga, nitsinda ryiza kandi ribi ion itsinda muburyo runaka bwa kristu yakozwe na ionic guhuza. Muri rusange, kristal ya ionic iravunika kandi irakomeye, hamwe no gushonga cyane hamwe no guteka, kandi irashobora gutwara amashanyarazi mugihe yashongeshejwe cyangwa yashonze. Ishingiro rya bateri zose za lithium-ion, harimo na tekinoroji ya lisiyumu ya fosifate, ni ionic conductivity. Byinshi mubikorwa bya kristu yimbere ya cathode ya lithium-ion ya cathode ifata gahunda ya "spinel structure", lithium manganate, lithium cobaltate, bateri ya lithium ya batiri nkiyi, iyi miterere igizwe nibice umunani bya cubic bigizwe na selile spinel (ibice bikora hejuru ya kristu, irashobora kumvikana muburyo bwa kristu ya selile), selile noneho igahuzwa muburyo bwa octahedral. Ibinyuranye, imiterere ya elayo ya lithium fer fosifate kristal ni inkingi ngufi. Imiterere ya spinel ya bateri eshatu zavuzwe haruguru zifite umwihariko wazo. Batteri ya Litiyumu cobalt-aside ifite imikorere myiza muri rusange, ariko ubushobozi buke nibibazo byumutekano, kandi bihenze kumasoko; bateri ya lithium manganate kubera kubona ibikoresho neza, igiciro gito n'umutekano, ariko imikorere mibi ya cycle nububiko; batteri ya lithium ya ternary igamije guhuza ibitagenda neza byombi, ubushobozi bwiyongereye, kandi ituze ryimiterere ryateje imbere umutekano, ariko igiciro kiracyarihenze cyane, kuko gisaba kandi ibikoresho byibanze bya cobalt. Ingaruka rusange muri spinelbateri ya lithium-ionni uko imbaraga zitari nini, ntabwo zikwiranye nini-nini. Ni ibihe bintu biranga Bateri Solar LiFePo4？ Imirasire ya tekinoroji ya Solar LiFePo4 hamwe nubukungu, kurundi ruhande, birakwiye gusa kubintu byo kubika ingufu murugo. By'umwihariko. 1. ingufu za batiri izuba LiFePo4 iringaniye: voltage nominal 3.2V, guhagarika amashanyarazi yumuriro 3.6V, guhagarika amashanyarazi ya voltage 2.0V. 2. ubushobozi buhanitse, hamwe nubucucike bwa 170mAh / g. 3. ituze ryiza ryumuriro hamwe nubushyuhe bwo hejuru. 4. kubika ingufu ziciriritse, ibikoresho bya cathode bihuye na sisitemu nyinshi ya electrolyte. 5. guhagarika voltage ya 2.0V, ishobora gusohora ubushobozi bwinshi, nini nini kandi yuzuye. 6. Ibikoresho byiza bya voltage biranga, hamwe nuburinganire bwumuriro wacyo hamwe nogusohora voltage birashobora kuba hafi yumuriro w'amashanyarazi wagenwe. Ibikoresho bya tekinike byavuzwe haruguru bituma imbaraga n’umutekano byiza bigerwaho, biteza imbere cyane ikoreshwa rya bateri nini ya LiFePo4. Usibye ibiranga tekiniki, bateri ya LiFePo4 ifite ibyiza bibiri ku isoko: 1. ibikoresho fatizo bihendutse, umutungo mwinshi; 2. ntabwo irimo ibyuma byagaciro, bidafite uburozi, nibicuruzwa bitangiza ibidukikije. Ibi bituma porogaramu ya batiri ya lithium fer fosifate mumasoko mashya yimodoka yingufu zimurika, kandi igahinduka tekinoroji yo kubika ingufu za sisitemu yo kubika izuba. Solar Litiyumu icyuma cya Fosifate na Litiyumu Manganate, Litiyumu Cobaltate, Kugereranya Bateri ya Ternary LiFePo4battery na lithium manganate, lithium cobaltate, lithium ternary batteri ni ishami rimwe rya bateri ya lithium-ion, imikorere yayo ikoreshwa cyane cyane mubikoresha ingufu zituruka ku mirasire y'izuba, icyo gihe ikaba yitwa batiri ya lithium-fer. Kubwibyo, ibyiza bya batiri yizuba ya lithium fer fosifate yerekeza cyane cyane kubigereranya nizindi bateri mugukoresha ingufu. Ni muri urwo rwego, izagereranya ahanini ibyiza byayo na bateri ya lithium ya ternary na batiri ya aside-aside. Ubwa mbere, ibyiza byo kurwanya ubushyuhe bwo hejuru ugereranije na bateri ya lithium. SolarLiFePo4battery ifite imikorere myiza yubushyuhe bwo hejuru, irashobora kwihanganira ubushyuhe bwo hejuru bwa 350 ° C ~ 500 ° C, mugihe lithium manganate / lithium cobaltate isanzwe igera kuri 200 ° C gusa, ibikoresho bya batiri ya litiro yahinduwe nabyo bizaba hafi 200 ° C. Icya kabiri, batatu muri "bakuru" - inyungu yuzuye yo kuramba. Litiyumu ya fosifate ya batiri kurusha bateri ya aside-aside na bateri ya lithium ya ternary ifite ubuzima burebure. Bateri ya aside-aside muri "ubuzima burebure" ni inshuro 300 gusa, kugeza inshuro 500; batteri ya lithium ya ternary inshuro zigera ku 2000, gusaba nyirizina inshuro zigera ku 1000 ubushobozi buzangirika kugera kuri 60%; na lithium fer fosifate bateri yubuzima busanzwe inshuro 2000, mugihe hakiri 95% yubushobozi, igitekerezo cyubuzima bwikizunguruka Kugera inshuro zirenga 3000. Ugereranije na Batiri ya aside-aside ifite ibyiza byinshi 1. Ubushobozi bunini.Monomer irashobora gukorwa muri 5Ah ~ 1000 Ah (1 Ah = 1000m Ah), mugihe bateri ya aside-aside 2V monomer mubisanzwe ni 100Ah ~ 150 Ah, impinduka ni nto. 2. Uburemere bworoshye.Ubushobozi bumwe bwumuriro wa batiri ya LiFePo4 ni 2/3 byubunini bwa bateri ya aside-aside, uburemere ni 1/3 cyanyuma. 3. Ubushobozi bwo kwishyuza byihuse.Solar LiFePo4 yumuriro wa batiri kugeza kuri 1C, kugirango ugere ku gipimo kinini cyo kwishyuza; amashanyarazi ya acide-acide isabwa muri rusange hagati ya 0.1C ~ 0.2C, ntishobora kugera kumikorere yihuse. 4. Kurengera ibidukikije. Bateri ya aside-aside ibaho mubwinshi bwibyuma biremereye - isasu, itanga amazi yimyanda, mugihe bateri yizuba LiFePo4 idafite ibyuma biremereye, nta mwanda mubikorwa no kuyikoresha. 5. Imikorere ihenze cyane.Nubwo bateri ya aside-aside kubera ibikoresho byayo bihendutse, igiciro cyo kugura kiri munsi ya bateri yizuba ya LiFePo4, ariko mubuzima bwa serivisi no gufata neza ubukungu biri munsi ya bateri yizuba LiFePo4. Ibisubizo bifatika bifatika byerekana ko: bateri yizuba ya lithium fer fosifate irenze inshuro enye imikorere yikiguzi cya batiri-aside. Imirasire y'izuba LiFePo4battery rwose iri mubyerekezokubika ingufu.guhitamo ingufu z'umuryango guhitamo!
