Lithium iron phosphate o loʻo i ai i le tulaga o le phosphate lithium ore i le natura, o loʻo i ai se fausaga olivine faatulagaina. Lithium phosphate chemical molecular formula o le: LIMPO4, lea e lelei le lithium; o le u&39;amea ogatotonu o se tau lelei; o le phosphate e le lelei tolu-tau, e masani ona faʻaaogaina e avea o se mea faʻaoga lelei maa lithium. O le faʻaogaina o le lithium iron phosphate maa o: mea e teu ai le malosi, meafaigaluega eletise, taʻavale eletise mama, taʻavale eletise tetele, mea laiti ma le mana feaveaʻi, e aofia ai le lithium iron phosphate ma le eletise eletise fou mo le 45% o le aofaʻi o le phosphite.

Lona lua, o le lithium iron phosphate e pei o le lithium electrode mea faʻatusatusa i isi lithium battery mea lelei, o le fausaga o le olivine e sili atu ona malupuipuia, faʻalelei le siosiomaga, taugofie, umi, maualuga o le vevela, ma isi, o le lithium ion sili ona malosi O se tasi o mea lelei maa. O le faʻatinoga o le saogalemu o se ki PO mautu i tioata maualuga-phosphate, e faigata ona pala, ma o le a le faʻapipiʻiina faʻavae pe faʻatupuina oxides malosi i le taimi o le mamafa ma le maualuga o le vevela.

Ole ola fa&39;ata&39;amilo ole ola umi ole ta&39;amilosaga o le ma&39;a ta&39;i-acid e tusa ma le 300 taimi, o le ola tautua e i le va o le 1 ma le 1.5 tausaga. Ma o le numera o le lithium iron phosphate maa e mafai ona oʻo atu i le sili atu i le 2,000, faʻaaogaina le ola o le 7-8 tausaga.

O le maualuga o le vevela o le maualuga o le vevela o le phosphate e oʻo atu i le 350 ° C i le 500 ° C, ae o le lithium mangananate ma le lithium cobaltate e naʻo le 200 ° C. E masani lava ona manatu le siosiomaga faauo lithium iron phosphate maa e le o iai ni metala mamafa ma metala seasea, e le oona, e le faʻaleagaina, o se maa siʻosiʻomaga lanu meamata. O le moliaga ma le lafoaia o masini o le lithium iron phosphate e pei o se mea eletise lelei e ese mai i isi mea masani, ma o le moliaga ma le lafoaia o le eletise e atagia ai vaega e lua o le lithium iron phosphate, o le moliaga ma le lafoaia o le tali atu e faapea: pe a faʻateʻa, Li + faʻapipiʻi i le phosphite uʻamea i le LifePo4.

O le suiga o le Li + e tupu i le Lifepo4 / Fepo4 interface, o le mea lea e matua mafolafola le faʻatonuga ma le tuʻuina atu, o le gafatia e sili atu ona mautu, talafeagai mo mea eletise. Tolu, o le sauniuniga o le lithium iron phosphate sauniuniga o mea e aofia ai ma le lithium iron phosphate. O nisi puna masani lithium, puna uʻamea, puna kaponi, ma puna phosphorus e faʻapea: O le sauniuniga o le lithium iron phosphate powder e mafai ona aʻafia ai lona faʻatinoga o se mea lelei.

E tele auala mo le saunia o le lithium iron phosphate, e pei o le maualuga o le vevela o le faʻaogaina o le vaega, le faʻaitiitia o le vevela o le carbon, ma le auala e le faʻaogaina ai le hydrothermal, faʻafefeteina vaifofo, metotia sol-gel, auala aofaʻi o timuga, ma isi. 1. O le maualuga o le vevela o le faʻaogaina o le vaega ole auala maualuga ole vevela ole faʻaogaina o le faʻaogaina o le lithium iron phosphate o le atinaʻe sili ona matua o le atinaʻe o loʻo iai nei ma le auala sili ona faʻaaogaina.

A maeʻa le puna uʻamea, puna lithium, faʻafefiloi puna phosphorus ma se mita vailaʻau nai lo toniga fefiloi, i se atemosifia inert, muamua sintered 5 i le 10 h i se vevela maualalo (300 ~ 350 ° C), ina ia muamua decomposed le mea mata, ona i luga o le vevela maualuga (600 ~ 800 ° C) Sintering ituaiga 10 iron oli phosphate. O le maualuga o le vevela o le faʻaogaina o le faʻaogaina o le lithium iron phosphate process e faigofie, o tulaga sauniuni e faigofie ona pulea, o le faʻaletonu o le tele o le tioata, e le faigofie ona pulea le lapisi, e le tutusa le tufatufaina, e le masani foi le foliga, e leaga le oloa. 2.

auala fa&39;aitiitiga vevela carbonatic auala fa&39;aitiitiga vevela carbon fa&39;aputuina puna carbon (mago, sucrose, ma isi) i mea mata fefiloi, e masani ona faʻaaogaina faʻatasi ma le maualuga vevela vaega mautu, ma le puna carbon e mafai ona faaitiitia Fe3 + i le vevela maualuga calcination i Fe2 +, Aloese mai le tali i le taimi o le tali e avea Fe3 +, ina ia sili atu le talafeagai le faagasologa o le synthesis, ae o le taimi o le tali e sili atu ona umi. 3.

Fa&39;asa&39;o vaifofo vevela fa&39;asa&39;o pyrolysis o se auala lelei e maua ai le toniga vaega ma foliga masani o le lithium iron phosphate pauta. O le mea muamua o loʻo faʻapipiʻiina o se reactor o le 450 i le 650 ° C faʻatasi ai ma le kesi vaʻaia, ma o le lithium iron phosphate e maua pe a maeʻa le maualuga o le vevela. E maualuga le fog fog spherical spheroid spherical spheroid saunia e le pyrolysis spray, ma e tutusa le tufaina o le lapopoa.

A maeʻa le maualuga o le vevela, e maua le pneumophosphate. Lithium iron phosphate sphere e faʻamalosia i le faʻateleina o le vaega patino o le meafaitino, faʻateleina le maualuga o le malosi o le meafaitino. 4.

O le faʻavevelaina o le vai o se auala faʻapipiʻi vai, e faʻatatau i se gaioiga faʻamaʻi i totonu o se vaʻa faʻamaufaʻailogaina i totonu o se vaʻa faʻamaufaʻailogaina, ma faʻafefeteina e le mea mata, fufuluina e ala i le faʻamamaina, faʻamago pe a uma ona faʻagogo. Lithium iron phosphate e mafai ona maua pe a maeʻa le maualuga o le vevela. Sauniuniga o le ferrite i le hydrothermal metotia o loʻo i ai le lelei o le pulea faigofie o foliga tioata ma le tele o mea laiti, o le lautele o le vaega, laʻititi laʻititi laʻititi, faiga faigofie, ae manaʻomia le maualuga o le vevela ma le mamafa o meafaigaluega, tau maualuga, lavelave faiga faigata.

I le faaopoopo atu i le auala o loʻo i luga, o loʻo i ai se auala masani faʻafefe, o le sol-gel method, o le faʻamaʻi faʻamaʻi faʻamaʻi, o se auala faʻamago emulsified, ma le microwave sintering metotia. 4. Aotelega E ui lava o le sauniuniga o le lithium iron phosphate e sili atu, sei vagana ai le maualuga o le vevela o le faʻaogaina o le vaega faʻamalosi, o le tele o suʻesuʻega suʻesuʻega.

Faatasi ai ma le faʻaauau pea ona faʻalolotoina o sauniuniga ma le faʻaleleia o le phosphate, o le saoasaoa o pisinisi o le ferrite phosphate e faʻavaveina pea. Ina ia aʻoaʻoina le alualu i luma o mea fou o le lithium iron-ion battery positive material, faamolemole saini mo le 2017 Energy Particle Material Preparation and Testing Technology Seminar i Oketopa 16-17! I lena taimi, Polofesa, le Polofesa, Hu Guorong, Iunivesite Tutotonu i Saute, o le a faasoa atu le lipoti o le "Lithium-Ion Battery Positive Code Material Lithium Lithium Lithium Industrialization". Sui Faatonu o le Inisetiute o Metallurgy ma Siosiomaga, Central South University, Sui Faatonu o le Inisetiute o Tekinolosi, Matagaluega o Advanced Battery, Matagaluega o Inisinia, Saina, Saina Chemistry ma le Malosiaga Malosiaga, China Lithium Battery Association, International Power Supply Commission, Lithium Battery Communication Committee.

E masani ona auai i le electrochemical theory ma le faʻaaogaina, mea malosi ma isi vaega, ma ua ausia taunuʻuga faʻapitoa i le atinaʻeina ma le gaosiga o mea eletise eletise eletise lithium-ion. Taofi ma auai i le sili atu i le 20 galuega faatino suesuega faasaienisi a le atunuu ma itumalo, e aofia ai se galuega faapitoa o alamanuia tele a le National Atinae ma Toefuataiga Komisi, o se tasi o le National Saienisi ma Tekinolosi Matagaluega o 863, e nafa ma le atunuu faasaienisi ma tekinolosi lagolago fuafuaga fuafuaga, o se fuafuaga moligao fuafuaga a le atunuu Aitema ma le tele o galuega autu faasaienisi ma tekinolosi i le Itumalo o Hunan. O fa&39;ai&39;uga fa&39;atosina ua maua i le fa&39;aulufaleina o mea fa&39;aeletise lelei maa lithium-ion, ma fa&39;ataunu&39;u manuia le tino o le lithium cobalt, lithium manganate ma le lithium iron phosphate.

E uiga i le 2017 Energy Granular Material Preparation and Testing Technology Seminar O lenei fonotaga e faʻamoemoe e tuʻuina atu faʻasalalauga fesoʻotaʻiga mo tagata atamamai talafeagai i le fale ma fafo, i le faʻaaogaina o le malosi granules, faʻamalosia le fefaʻatauaʻiga o faʻamatalaga tau pisinisi, lithium battery, capacitor, fuel cell , Eletise taʻavale maa tekinolosi faʻalavelave faia saofaga.
