著者：Iflowpower – Provedor de central eléctrica portátil

Lithium iron phosphate kei te ahua o te phosphate lithium ore i roto i te taiao, he hanganga olivine raupapa. Lithium phosphate tātai rāpoi matū ko: LIMPO4, he pai te lithium; he utu pai te rino whakarewa pokapū; he kino te utu e toru nga utu o te phosphate, he maha nga wa e whakamahia ana hei taonga pai o te pākahiko lithium. Ko te tono o nga pākahiko lithium iron phosphate ko: nga taputapu rokiroki hiko, nga taputapu hiko, nga waka hiko marama, nga waka hiko nui, nga taputapu iti me te kaha waea, tae atu ki te lithium rino phosphate me nga waka hiko hiko hou mo te 45% o te tapeke o te phosphite.

Tuarua, ko te lithium rino phosphate hei taonga hiko lithium ka whakatauritea ki etahi atu taputapu pai o te pākahiko lithium, he pai ake te hanganga olivine, he pai te taiao, he iti, he wa roa, he mahi teitei o te pāmahana, me etahi atu, ko te katote lithium tino kaha Ko tetahi o nga rauemi pai o te pākahiko. Ko te mahi haumaru he matua PO totoka i roto i nga tioata-phosphate teitei, he uaua ki te pirau, karekau e tiango te hanga, ka whakaputa waikura kaha ranei i te wa e nui ana te utu me te wera nui.

Te roa o te huringa o te pākahiko mata-waikawa e tata ana ki te 300 nga wa, ko te oranga mahi kei waenganui i te 1 me te 1.5 tau. Na te maha o te pākahiko lithium rino phosphate ka taea te neke atu i te 2,000, ka whakamahia te oranga o te 7-8 tau.

Ko te mahi teitei o te pāmahana he teitei te wera o te rino-kore phosphate nga tihi waiariki ki te 350 ° C ki te 500 ° C, ko te lithium manganate me te lithium cobaltate he 200 ° C noa iho. Ko te pākahiko lithium rino Phosphate pai-taiao e kiia ana kaore he konganuku taumaha me nga konganuku onge, kore-paitini, kore-polluting, he pākahiko taiao matomato tonu. Ko te tikanga utu me te tukunga o te lithium rino phosphate hei taonga hiko pai he rereke mai i etahi atu rauemi tikanga, a ko te utu me te tukunga o te hikohiko e whakaatu ana i nga waahanga e rua o te lithium rino phosphate, ko te utu me te tukunga o te tauhohenga ko enei e whai ake nei: te tauhohenga utu: Te tauhohenga tuku: Utu, Li + Mai i te LifePO4, Fe2 + kua ngaro tetahi irahiko ki te FE3 +; ka tukuna, ka whakauruhia a Li + ki roto i te rino phosphite ki LifePo4.

Ko te huringa o Li + ka puta i roto i te atanga Lifepo4 / Fepo4, na reira he tino papatahi te utu me te whakahekenga, he pai ake te kaha, he pai mo nga taonga hiko. Tuatoru, te faaineineraa o te lithium rino phosphate faaineineraa o kai ki te lithium rino phosphate. Ko etahi puna lithium noa, puna rino, puna waro, me te puna ūkuikui e whai ake nei: Ko te whakarite o te paura lithium rino phosphate ka pa ki tana mahi hei taonga pai.

He maha nga tikanga mo te whakarite o te lithium rino phosphate, penei i te tauhohenga o te wahanga totoka teitei o te wera, te tikanga whakaheke waiariki waro, me te tikanga waiariki kore, rehu waiariki waiariki, tikanga sol-gel, tikanga rerenga katoa, aha atu. 1. High pāmahana tikanga tauhohenga wāhanga totoka tiketike pāmahana tikanga tauhohenga wāhanga totoka ko ki te whakarite lithium rino phosphate ko te whanaketanga tino pakeke o te whanaketanga o nāianei, me te tikanga tino whakamahia whānuitia.

I muri i te puna rino, te puna lithium, te puna ūkuikui i konatunatua ki te mita matū atu i te whakakotahitanga i konatunatua, i roto i te hau hau, i te tuatahi ka sintered 5 ki te 10 h i te pāmahana raro (300 ~ 350 ° C), kia te tuatahi decomposed te rauemi raw, ka i roto i te pāmahana teitei ( 600 ~ 800 ° C) Sintering momo lithium 10 ~ oli phosphate. Ko te tikanga o te waahanga totoka teitei te whakahiato o te tukanga lithium rino phosphate he ngawari, he ngawari te whakahaere i nga tikanga whakarite, ko te ngoikoretanga ko te rahi o te karaihe, ko te diameter o te matūriki kaore i te ngawari ki te whakahaere, he rereke te tohatoha, he rereke te ahua, he kino te awhe hua. 2.

tikanga whakaiti waiariki waro tikanga whakaiti waiariki waro ko ki te tāpiri puna waro ( māngaro, sucrose, me ētahi atu) i roto i te ranu rauemi raw, te tikanga whakamahia tahi ki te pāmahana teitei wāhanga totoka, a ka taea e te puna waro whakaiti Fe3 + i roto i te pāmahana teitei calcination ki Fe2 +, A ape i te tauhohenga i roto i te tauhohenga ki te riro Fe3 +, kia he atu whaitake te tukanga kōtuitanga, engari ko te roa o te mana tauhohenga. 3.

Ko te rehu wairewa wera rehu pyrolysis he huarahi whai hua ki te whiwhi i te rahi matūriki rite me te ahua o te paura lithium rino phosphate. Ko te kaamua ka whakauruhia ki te reactor o te 450 ki te 650 ° C me te hau kawe, ka whiwhi te lithium rino phosphate i muri i nga tauhohenga teitei o te pāmahana. He teitei te kohu o te kohu porohita porohita kua whakaritea ma te rehu pyrolysis, he rite te tohatoha rahi matūriki.

I muri i nga tauhohenga teitei o te pāmahana, ka whiwhi te pneumophosphate. Ko te kopae rino phosphate Lithium he pai ki te whakanui ake i te waahanga mata motuhake o te papanga, te whakanui ake i te kaha ōwehenga o te rauemi. 4.

Ko te tikanga whakawera wai he tikanga whakahiato wai, e pa ana ki te tauhohenga matū i roto i te oko pehanga hiri i roto i te oko pehanga hiri, a he matū te tauhohenga e te rauemi mata, ka horoia ma te filtration, ka whakamaroke i muri i te whakamaroketanga. Ka taea te whiwhi i te rino phosphate Lithium i muri i te calcined te pāmahana teitei. Ko te whakarite o te ferrite i roto i te tikanga hydrothermal he painga o te whakahaere ngawari o te ahua tioata me te rahi o te matūriki, te diameter o te matūriki toharite, te iti o te matūriki, te tukanga ngawari, engari me te nui o te wera me te taputapu teitei, te utu nui, te uaua o te tukanga.

I tua atu i te tikanga o runga ake nei, he tikanga rewharewha noa, he tikanga sol-gel, he tikanga whakaheke oxidative-reduction, he tikanga whakamaroke whakaemulsi, he tikanga whakamaroke ngaruiti. 4. Whakarāpopototanga Ahakoa te tikanga whakarite o te lithium rino phosphate he nui noa atu, engari mo te tikanga tauhohenga o te waahi totoka teitei, te nuinga o te waahanga rangahau taiwhanga.

Na te hohonutanga o te whakarite me te whakarereketanga o te phosphate, ka tere te tere o te ahumahi o te ferrite phosphate.
