Bizibu ki ebiri mu kuddamu okukola bbaatule za lithium iron phosphate?

Battery za lithium iron phosphate zirina eddagala eriyitibwa LiPF6, organic carbonate, copper. Nga kwotadde n’ebintu ebisatu waggulu bikolebwa mu lukalala lwa kasasiro ow’obulabe mu ggwanga.LiPF6 esaanyaawo nnyo era kyangu okuvunda ng’ekwatagana n’amazzi okukola HF; ebizimbulukusa eby’obutonde awamu n’okusasika kwabyo awamu n’ebintu ebisengejja amazzi mazima ddala bijja kuleeta obucaafu obw’amaanyi mu mpewo eri embeera, amazzi, ettaka, awamu n’okulumya obutonde; Ebyuma ebizito nga ekikomo bikuŋŋaana mu bbanga era ku nkomerero ne biteeka abantu mu matigga n’olujegere lw’ebiramu; phosphorus bw’ayingira mu nnyanja era n’amazzi amalala, kyangu nnyo okuleeta eutrophication y’amazzi. Kiyinza okulabibwa nti singa bbaatule za lithium iron phosphate ezisuuliddwa teziddamu kukozesebwa, kijja kuleeta obulabe obw’ekitalo eri obutonde bw’ensi wamu n’obulamu bw’abantu n’obulamu obulungi.

Olw’okukulaakulana okw’amangu okw’ekitongole ky’emmotoka ez’amasannyalaze mu maka, obwetaavu bwa bbaatule za lithium iron phosphate bweyongedde okulinnya amangu. Battery nnyingi ez’amaanyi ga lithium iron phosphate mu butuufu zibadde zisuuliddwa era nazo zigenda mu mutendera gw’okuddamu okukola. Akatale k’okuddamu okukola bbaatule za lithium kalaze okukula okw’amaanyi., Bizibu ki ebiriwo mu kuddamu okukola bbaatule za lithium iron phosphate?

1. Tekinologiya w’okuddamu okukola ebintu si mukulu

Ebintu ebiriwo biraga nti okuddamu okukola bbaatule za lithium iron phosphate eza kasasiro kwawulwamu ddala mu bika 2: ekimu kwe kuzzaawo ebyuma, ate era ekirala kwe kuzzaawo ebintu ebiva mu lithium iron phosphate cathode.

( 1. Okuwona okunnyogovu okwa lithium nga kwotadde n’ekyuma

Enkola ey’ekika kino okutwalira awamu ya kuzzaawo lithium. Okuva bwe kiri nti lithium iron phosphate terimu byuma bya muwendo, enkola y’okuzzaawo lithium cobaltate ekolebwa ku mutindo. Ekisooka, bbaatule ya lithium iron phosphate eggyibwamu okusobola okufuna ekintu ekirungi eky’obusannyalazo, ekifuumuulwa nga kw’otadde n’okusengejja okusobola okufuna butto; oluvannyuma lw’ekyo eky’okulonda kya alkaline kiyingizibwa mu butto okufuula aluminiyamu amazzi awamu ne aluminiyamu oxides ezizitowa ennyo, era n’ebisigadde mu ffilta ebirimu lithium, ekyuma, n’ebirala bifunibwa nga bisengejebwa; Eddagala erigatta asidi wa salufaali era ne haidrojeni perokisayidi (minimizing representative) liyisibwa okusobola okufuna ekisengejjero ekikulukuta; omuli alkali okwanguya ferric hydroxide, era n’enkola y’okusengejja okusobola okufuna ekisengejja; okusaanuusa ferric hydroxide okufuna ferric oxide; ekisembayo okukyusa omuwendo gwa pH ogw’eddagala ly’okukulukuta (5.0 ~ 8.0), okusengejja Ekisengejja kifunibwa okuva mu kisengejjero ekikulukuta, awamu ne sodium carbonate ow’amaanyi kiyambibwako okussa essira era n’okufuuka ekiristaayo okufuna lithium carbonate.

( 2. Lithium iron phosphate eyakomezeddwawo

Okuwona omulundi gumu okw’ekintu ekigere kifuula omugaso gw’ebyenfuna ogw’okuzzaawo lithium iron phosphate awatali byuma bya muwendo okuba omutono ennyo. N’ekyavaamu, okuzza obuggya mu mutendera omugumu (solid-phase regeneration) kwa lithium iron phosphate kusinga kukozesebwa kukola ku bbaatule za lithium iron phosphate eza kasasiro. Enkola eno erina emigaso mingi egy’okuzzaawo nga kwotadde n’omuwendo omunene ogw’okukozesa eby’obugagga mu bujjuvu.

Ekisooka, bbaatule ya lithium iron phosphate eggyibwamu okusobola okufuna ekintu kya positive electrode, ekibetentebwa ne kisengejebwa okufuna butto; oluvannyuma lw’ekyo, graphite ne binder ebiddirira biggyibwawo nga bikozesebwa ebbugumu, era oluvannyuma lw’ekyo eddagala lya alkaline liteekebwa mu butto okufuula aluminiyamu omuzito omutono awamu ne aluminiyamu oxides amazzi; Ekifo eky’okusengejja omuli lithium, ekyuma, n’ebirala, okwekenneenya omugerageranyo gw’amalola g’ekyuma, lithium awamu ne phosphorus mu kifo ekitereka ekyuma, okutwaliramu eky’obugagga ky’ekyuma, eky’obugagga kya lithium n’ensibuko ya phosphorus, okuddamu okutereeza omugerageranyo gw’amalola g’ekyuma, lithium awamu ne phosphorus okutuuka ku 1:1:1; add carbon source, Oluvannyuma lw’okusiba omupiira, ekintu ekipya ennyo ekya lithium iron phosphate cathode kifunibwa nga kifukibwa mu bbanga eritaliiko maanyi.

Ekyokubiri, enkola y’okuddamu okukozesa si nnungi nnyo

Wadde ng’ebitongole n’ebitongole ebirina ebisaanyizo bitumbula nnyo bbaatule za lithium iron phosphate, olw’omuwendo omunene ogw’emmotoka eziteekebwa mu ggiya, okuddamu okukozesa kukyali mu ntandikwa, enkola eriwo ey’okuddamu okukola ebintu tetuukiridde, era enkola ey’ekikugu ey’okuddamu okukozesa bbaatule z’amaanyi g’emmotoka tennaba kukolebwa. Enkola y’okuddamu okukola ebintu eriwo erina obuzibu obw’enjawulo, era n’omutindo gw’okuddamu okukola ebintu gukendeera. Ekizibu kino kisinga kuva ku kugoberera facets:

1. Less recyclable amount

Omuwendo omunene ogwa bbaatule ezikozesebwa zisaasaanyizibwa mu mikono gy’abantu ssekinnoomu, wabula abantu tebalina kifo we baziteeka, kale zikolebwako wamu ne kasasiro w’amayumba, okukakasa nti ekika kya bbaatule ezikozesebwa eziddizibwa okuva mu bantu ssekinnoomu kumpi nedda. Ebintu ebikadde oba eby’edda mu sitoowa, ekika kya bbaatule z’amaanyi ennene ennyo ezizzeemu nazo ntono.

2. Enkola y’okuddamu okukola si y’esinga

Enkola eyeewaddeyo okuddamu okukola bbaatule mu butuufu tennaba kuteekebwawo mu China, nga kw’otadde n’okusinga okukung’aanya okujjuvu okw’emisomo emitonotono. eggwanga lyange likola nnyo era likozesa bbaatule za lithium-ion, naye olw’omuwendo gwayo omunene, bbaatule ezirina buli mutwe ntono nnyo. Okumala ebbanga ddene, okuddamu okukozesa bizinensi tekyaddamu kukozesa bbaatule za lithium-ion ezenjawulo ezaali tezirina mugaso gwa kuddamu kukola.

.

​Wabula waliwo kkampuni entonotono nnyingi nnyo nga kw’otadde n’eza tekinologiya omutono, ezireeta obuzibu nti bbaatule tezisobola kukuŋŋaanyizibwa mu ngeri ya wakati.

4. Ensaasaanya ennene ey’okuzzaawo

A ebintu bingi ebya lithium iron phosphate bikozesebwa mu electrode ennungi eya bbaatule z’amaanyi oba ezitereka amaanyi, awamu n’obwetaavu businga nnyo obwa bbaatule entono eza bulijjo. Okuddamu okuzikozesa kirina omugaso munene mu bantu, naye ate ssente ezisaasaanyizibwa mu kuddamu okukola ziri waggulu, era era ne bbaatule za lithium iron phosphate tezirimu Steels za muwendo nga zirina omuwendo gw’ensimbi ogukendedde.
