Ni izihe ngorane zo gutunganya bateri ya lithium fer fosifate?

Litiyumu ya fosifate ya batiri ifite ibikoresho bya shimi bya LiPF6, karubone kama, umuringa. Nkuko ibikoresho bitatu byavuzwe haruguru bikorwa murutonde rwimyanda yangiza igihugu.LiPF6 irasenya cyane kandi irashobora kubora byoroshye guhura namazi kugirango itange HF; imashanyarazi karemano kimwe no gusenyuka kwayo hamwe nibintu bya hydrolysis bizatera rwose ihumana ry’ikirere ibidukikije, amazi, ubutaka, ndetse no kwangiza ibidukikije; Ibyuma biremereye nk'umuringa bikusanyiriza mu kirere kandi amaherezo bikabangamira abantu n'umunyururu ngenga; iyo fosifore yinjiye mu biyaga ndetse nandi mazi y’amazi, biroroshye cyane gukurura eutrophasi yimibiri yamazi. Birashobora kugaragara ko niba bateri za lithium fer fosifate zajugunywe zidatunganijwe neza, bizatera ingaruka mbi kubidukikije kimwe nubuzima bwabantu nubuzima bwiza.

Hamwe niterambere ryihuse ryimodoka itwara amashanyarazi atuye, icyifuzo cya batiri ya lithium fer fosifate cyiyongereye vuba. Batteri nyinshi za lithium fer fosifate yamashanyarazi yaracukuwe kandi nayo yagiye mugice cyo gutunganya. Isoko rya lithium itunganyirizwa isoko ryerekanye gukura guturika., Ni ibihe bibazo bihari bya lithium fer fosifate ikoreshwa?

1.Ikoranabuhanga rya recycling ntabwo rikuze

Ibisobanuro biriho byerekana ko gutunganya imyanda ya batiri ya lithium fer fosifate yatandukanijwe muburyo bubiri: kimwe nukugarura ibyuma, kandi ikindi nukugarura lithium fer fosifate cathode.

(1. Gukiza neza kwa lithium kimwe nicyuma

Ubu bwoko bwuburyo busanzwe bwo kugarura lithium. Kubera ko fosifate ya lithiyumu idafite ibyuma byagaciro, inzira yo kwisubiramo ya lithium cobaltate irateganijwe. Ubwa mbere, bateri ya lithium fer fosifate yatandukanijwe kugirango ibone ibicuruzwa byiza bya electrode, bisunikwa kimwe no gushungura kugirango ubone ifu; nyuma yibyo, alkaline ihitamo gushiramo ifu kugirango isukure aluminium kimwe nuburemere bwa aluminiyumu ya aluminiyumu, kandi ibisigara bya filteri irimo lithium, fer, nibindi bibonwa no kuyungurura; Umuti uhuriweho na acide sulfurike na hydrogène peroxide (kugabanya uhagarariye) irekurwa kugirango ibone igisubizo kiboneye; harimo alkali kugirango yihutishe hydroxide ferricike, kandi na sisitemu yo kuyungurura kugirango ibone kuyungurura; gushonga hydroxide ferricike kugirango ibone okiside ferric; nyuma, guhindura pH agaciro k'umuti wo kumeneka (5.0 ~ 8.0), kuyungurura Akayunguruzo gakurwa mubisubizo byamazi, kimwe na karubone ikomeye ya sodium igira uruhare mukwibanda kandi ikanaboneka kugirango ibone karubone ya lithium.

(2. Kugarura lithium fer fosifate

Gukiza kimwe k'ikintu runaka bituma inyungu zubukungu zisubirana kwa fosifate ya lithium idafite ibyuma bifite agaciro gake. Kubera iyo mpamvu, kuvugurura ibyiciro bikomeye bya lithium fer fosifate ikoreshwa cyane cyane mugukemura imyanda ya litiro fer ya fosifate. Iyi nzira ifite inyungu nyinshi zo gukira kimwe nigipimo kinini cyo gukoresha ibikoresho.

Ubwa mbere, batiri ya lithium fer fosifate yatandukanijwe kugirango ibone ibikoresho byiza bya electrode, byajanjaguwe bikayungurura kugirango ibone ifu; nyuma yibyo, grafite na binder bigenda bisubirwamo bivanwaho no kuvura ubushyuhe, hanyuma nyuma yumuti wa alkaline ushyirwa mubifu kugirango uhindure aluminiyumu yoroheje kimwe na oxyde ya aluminium; Kurungurura kubitsa harimo lithium, fer, nibindi, suzuma igipimo cyumubyimba wicyuma, lithium kimwe na fosifore mububiko bwayunguruzo, ushizemo umutungo wicyuma, umutungo wa lithium nisoko ya fosifore, hindura igipimo cyimyuka ya fer, lithium kimwe na fosifore kuri 1: 1: 1; ongeramo isoko ya karubone, Nyuma yo gusya umupira, ibintu bishya bya lithium fer fosifate cathode ibikoresho biboneka mukubara mukirere cya inert.

Icya kabiri, sisitemu yo gukoresha ntabwo ari nziza

Nubwo amacakubiri yujuje ibyangombwa n’inganda biteza imbere cyane bateri ya lithium fer fosifate, kubera umubare munini wimodoka zitegurwa, kongera gukoresha biracyari mu ntangiriro zayo, sisitemu isanzwe ikoreshwa neza ntabwo itunganye, kandi sisitemu yinzobere yo gukoresha ingufu za batiri zikoreshwa ntizigeze zikorwa. Sisitemu iriho yo gutunganya ibintu ifite ibibazo byihariye, kandi nuburyo bwo gutunganya ibicuruzwa buragabanuka. Iki kibazo ahanini gikururwa no kubahiriza ibice:

1. Umubare muke udasubirwamo

Umubare munini wa bateri wakoreshejwe ukwirakwizwa mumaboko yabantu, icyakora abaturage ntibafite aho babashyira, bityo bakemurwa hamwe n imyanda yo guturamo, kugirango barebe ko bateri zitandukanye zikoreshwa zisubizwa mubantu ku giti cyabo hafi ya zose. Ibisigazwa cyangwa ibicuruzwa bishaje mububiko, ubwoko bwa bateri nini zingufu zongeye kugaruka nabwo ni buke.

. igihugu cyanjye nigikorwa gikomeye kandi kigakoresha bateri ya lithium-ion, nyamara kubera ubwinshi bwayo, buri bateri kumutwe ni muto. Mu gihe kirekire, kongera gukoresha ubucuruzi ntibyongeye gukoresha bateri ya lithium-ion idafite agaciro kayo.

. Nyamara, hari byinshi bito bito kimwe n’ikoranabuhanga rito, bitera ikibazo ko bateri idashobora gukusanyirizwa hamwe.

4

. Kubikoresha bifite agaciro gakomeye mumibereho, nyamara amafaranga yo gutunganya ibicuruzwa ni menshi, kandi na bateri ya lithium fer fosifate ntabwo ikubiyemo ibyuma bifite agaciro kagabanutse kumafaranga.
