Ibyiza bya batiri ya lithium fer fosifate
1. Kunoza imikorere yumutekano
Inkunga ya PO muri lithium fer fosifate kristal irahagaze kandi iragoye kubora.Ndetse no ku bushyuhe bwinshi cyangwa hejuru cyane, ntabwo izasenyuka kandi ikabyara ubushyuhe nka lithium cobalt oxyde cyangwa ngo ikore ibintu bikomeye bya okiside, bityo ifite umutekano mwiza.Raporo yerekanye ko mu gikorwa nyirizina, umubare muto w'icyitegererezo wasangaga utwikwa mu bushakashatsi bwa acupuncture cyangwa mu gihe gito, ariko nta guturika kwabaye.ibintu biturika.Nubwo bimeze bityo, umutekano wacyo urenze urugero watejwe imbere cyane ugereranije na bateri isanzwe ya electrolyte lithium cobalt oxyde.
2. Gutezimbere ubuzima bwawe
Litiyumu ya fosifate ya batiri bivuga bateri ya lithium ion ikoresha fosifate ya lithium nkibikoresho byiza bya electrode.
Ubuzima bwa cycle yubuzima burebure bwa batiri-aside irikuba inshuro zigera kuri 300, kandi ntarengwa ni inshuro 500, mugihe ubuzima bwikurikiranya bwa lithium fer fosifate yamashanyarazi ishobora kugera inshuro zirenga 2000, hamwe no kwishyuza bisanzwe (igipimo cyamasaha 5) gukoresha birashobora gushika incuro 2000.Batiri ya aside-aside ifite ubuziranenge ni "umwaka mushya, umwaka ushize, no kubungabunga no kubungabunga igice cyumwaka", ni imyaka 1 ~ 1.5 byibuze, kandi batiri ya lithium fer fosifate ikoreshwa mubihe bimwe, ubuzima bwa theoretical buzagera kumyaka 7 ~ 8.Urebye neza, igipimo cyibikorwa-igiciro ni inshuro zirenze 4 za bateri ya aside-aside.Gusohora kwinshi-birashobora kwihuta no gusohora hejuru-2C.Munsi ya charger idasanzwe, bateri irashobora kwishyurwa byuzuye muminota 40 yumuriro wa 1.5C, kandi itangira rishobora kugera kuri 2C, ariko bateri ya aside-aside ntabwo ifite iyi mikorere.
3. Imikorere myiza yubushyuhe bwo hejuru
Amashanyarazi ashyushye ya lithium fer fosifate ashobora kugera kuri 350 ℃ -500 ℃, mugihe lithium manganate na lithium cobaltate iri hafi 200 only.Ubushyuhe bukabije bwo gukora (-20C - 75C), hamwe nubushyuhe bwo hejuru, ubushyuhe bwo gushyushya amashanyarazi ya lithium fer fosifate burashobora kugera kuri 350 ℃ -500 ℃, naho lithium manganate na lithium cobaltate ni 200 ℃ gusa.
4. Ubushobozi bunini
Batteri akenshi ikora muburyo bwo kwishyurwa byuzuye, kandi ubushobozi buzagabanuka vuba munsi yubushobozi bwagenwe.Iyi phenomenon yitwa ingaruka yibuka.Kimwe na nikel-icyuma hydride na bateri ya nikel-kadmium, hariho kwibuka, ariko bateri ya lithium fer fosifate ntabwo ifite iki kintu.Ntakibazo uko bateri yaba imeze, irashobora gukoreshwa umwanya uwariwo wose utiriwe uyisohora mbere yo kwishyuza.
5. Uburemere bworoshye
Ingano ya batiri ya lithium fer fosifate ifite ibisobanuro bimwe nubushobozi ni 2/3 byubunini bwa batiri ya aside-aside, naho uburemere ni 1/3 cya batiri ya aside-aside.
6. Kurengera ibidukikije
Batiyeri ya Lisiyumu ya fosifate muri rusange ifatwa nkaho idafite ibyuma biremereye ndetse nicyuma kidasanzwe (bateri ya nikel-metal hydride ikenera ibyuma bidasanzwe), idafite uburozi (SGS yemejwe), idahumanya, yubahiriza amabwiriza y’iburayi RoHS, kandi ni byimazeyo Icyemezo cya batiri icyatsi.Kubwibyo, impamvu bateri ya lithium itoneshwa ninganda ahanini biterwa no gutekereza kubidukikije.Kubera iyo mpamvu, bateri yashyizwe muri “863 ″ gahunda y’iterambere ry’ikoranabuhanga mu rwego rw’igihugu mu gihe cya“ Gahunda y’imyaka icumi y’imyaka itanu ”, kandi yabaye umushinga w'ingenzi ushyigikiwe kandi ushishikarizwa na Leta.Ubushinwa bwinjiye muri WTO, ibicuruzwa byoherezwa mu mahanga by’amagare y’amashanyarazi mu Bushinwa biziyongera vuba, kandi amagare y’amashanyarazi yinjira mu Burayi no muri Amerika asabwa kuba afite bateri zidahumanya.
Icyakora, impuguke zimwe zavuze ko ihumana ry’ibidukikije ryatewe na bateri ya aside-aside iba cyane cyane mu buryo budasanzwe bwo gutunganya umusaruro no gutunganya inganda.Muri ubwo buryo, bateri ya lithium ni iy'inganda nshya, ariko ntishobora kwirinda ikibazo cy’umwanda mwinshi.Isasu, arsenic, kadmium, mercure, chromium, nibindi mugutunganya ibikoresho byibyuma birashobora kurekurwa mukungugu namazi.Batare ubwayo ni imiti, bityo irashobora gutera ubwoko bubiri bwumwanda: imwe ni inzira ihumanya imyanda mumusaruro;ikindi ni umwanda wa batiri nyuma yo gukuraho.
Batteri ya Litiyumu ya fosifate nayo ifite inenge: urugero, imikorere yubushyuhe buke irakennye, ubwinshi bwa robine yibikoresho bya electrode nziza ni bike, kandi ingano ya batiri ya lisiyumu fer fosifate ifite ubushobozi bungana ni nini kuruta iy'ibikoresho bya litiro ion nka lithium cobalt oxyde, ntabwo rero ifite ibyiza muri bateri ya micro.Iyo ikoreshejwe muri bateri yingufu, bateri ya lithium fer fosifate, kimwe nizindi bateri, igomba guhura nikibazo cyo guhuza bateri.
