Ibyiza

1. Kunoza imikorere yumutekano
Inkunga ya PO muri lithium fer fosifate kristal irahagaze kandi biragoye kubora.Ndetse no ku bushyuhe bwinshi cyangwa hejuru cyane, ntibishobora gusenyuka no kubyara ubushyuhe cyangwa gukora ibintu bya okiside ikomeye muburyo bumwe na lisiyumu ya cobalt, bityo ikagira umutekano mwiza.Raporo yerekanye ko mu bikorwa nyirizina, igice gito cy’icyitegererezo wasangaga cyaka mu bushakashatsi bwa acupuncture cyangwa mu gihe gito, ariko nta guturika kwabaye.Mu igeragezwa rirenze urugero, umuriro mwinshi wa voltage wakubye inshuro nyinshi ugereranije n’umuvuduko wo kwikuramo, kandi wasangaga hakiri ibintu biturika.Nubwo bimeze bityo ariko, umutekano wacyo urenze urugero ugereranije na bateri isanzwe ya electrolyte lithium cobalt oxyde.
2. Gutezimbere ubuzima
Batiri ya Litiyumu icyuma cya fosifatebivuga batiri ya lithium ion ukoresheje lithium fer fosifate nkibikoresho byiza bya electrode.
Ubuzima bwa cycle yubuzima burebure bwa aside-aside irikuba inshuro 300, naho hejuru ni inshuro 500.Batiri ya lithium fer fosifate ingufu za lithium ifite ubuzima bwikubye inshuro zirenga 2000, kandi igiciro gisanzwe (igipimo cyamasaha 5) gishobora kugera inshuro 2000.Bateri ya aside-aside iringaniye ni shyashya mugice cyumwaka, ishaje igice cyumwaka, no kubungabunga no kuyitunganya mugice cyumwaka, byibuze imyaka 1 kugeza 1.5, mugihe bateri ya lithium fer fosifate ikoreshwa mubihe bimwe izaba ifite ubuzima bwimyumvire yimyaka 7 kugeza 8.Urebye neza, igipimo cyibikorwa-nigiciro kirenze inshuro 4 za batiri ya aside-aside.Gusohora kwinshi birashobora kwihuta no gusohora hejuru ya 2C.Hamwe na charger yabigenewe, bateri irashobora kwishyurwa byuzuye muminota 40 ya 1.5C yishyuye.Intangiriro yo gutangira irashobora kugera kuri 2C, ariko bateri ya aside-aside idafite imikorere nkiyi.
3. Imikorere yubushyuhe bwo hejuru
Agaciro ntarengwa ka lithium fer fosifate yo gushyushya amashanyarazi irashobora kugera kuri 350 ℃ -500 ℃, mugihe lithium manganate na lithium cobaltate iri hafi 200 ℃.Ubushyuhe bukabije bwo gukora (-20C - 75C), hamwe nubushyuhe bwo hejuru, lithium fer fosifate yo gushyushya amashanyarazi irashobora kugera kuri 350 ℃ -500 ℃, mugihe lithium manganate na lithium cobaltate iri hafi 200 ℃.
4. Ubushobozi bunini
HenIyo bateri yumuriro ihora yuzuye kandi ntisohore, ubushobozi buzahita bugabanuka munsi yubushobozi bwagenwe.Iyi phenomenon yitwa ingaruka yibuka.Kimwe na hydride ya nikel na bateri ya nikel-kadmium, hariho kwibuka, ariko bateri ya fosifate ya lithium ntabwo ifite iki kintu.Ntakibazo leta yaba irimo, irashobora kwishyurwa no gukoreshwa mukimara kwishyurwa.
6, uburemere bworoshye
Ingano ya batiri ya lithium fer ya fosifate yubusobanuro bumwe nubushobozi ni 2/3 byubunini bwa batiri ya aside-aside, naho uburemere ni 1/3 cya batiri ya aside-aside.
7. Kurengera ibidukikije
Batteri ya Lisiyumu ya fosifate muri rusange ifatwa nkibidafite ibyuma biremereye ndetse nicyuma kidasanzwe (bateri ya nikel-hydrogène isaba ibyuma bidasanzwe), idafite uburozi (icyemezo cya SGS), idahumanya, ikurikije amabwiriza y’uburayi RoHS, kandi rwose Icyemezo cya batiri icyatsi.Kubwibyo, impamvu ituma bateri ya lithium-ion itoneshwa ninganda ni ngombwa kubera gutekereza kubidukikije.Kubwibyo, bateri yashyizwe muri 863 yigihugu yiterambere ryiterambere rya tekinoroji mugihe cyimyaka icumi yimyaka itanu kandi yabaye umushinga wingenzi wigihugu no gutera inkunga.Igihugu cyanjye cyinjiye muri WTO, igihugu cyanjye cyohereza amagare y’amashanyarazi aziyongera cyane, kandi amagare y’amashanyarazi yinjira mu Burayi no muri Amerika yasabwaga kuba afite bateri zitagira umwanda.
Icyakora, impuguke zimwe zavuze ko ihumana ry’ibidukikije ryatewe na batiri ya aside-aside ahanini ryabaye mu ruganda rutunganya umusaruro ndetse no gutunganya ibicuruzwa.Muri ubwo buryo, bateri ya lithium-ion ni iy'inganda nshya, ariko ntishobora gukumira umwanda mwinshi.Isasu, arsenic, kadmium, mercure, chromium, nibindi mugutunganya ibikoresho byibyuma birashobora kurekurwa mukungugu namazi.Batare ubwayo ni ubwoko bwimiti, kuburyo hashobora kubaho ubwoko bubiri bwumwanda: imwe ni ihumana ryimyanda ikorwa mubikorwa byubwubatsi;ikindi ni umwanda wa batiri nyuma yo gukurwaho.
Batteri ya Litiyumu ya fosifate nayo ifite ibyo idahwitse: kurugero, imikorere mibi yubushyuhe buke, ubukana buke bwibikoresho bya cathode, nubunini bwa batiri ya lithium fer fosifate ifite ubushobozi bungana na batiri ya lithium-ion nka lithium cobalt oxyde, ntabwo rero bafite ibyiza muri bateri ntoya.Iyo ikoreshejwe muri bateri ya lithium, bateri ya lisiyumu ya fosifate ni kimwe nizindi bateri, kandi bagomba guhura nibibazo bya batiri.
