Tam sim no, muaj ntau txoj hauv kev los npaj lithium hlau phosphate (Lifepo4 Powder), xws li high-temperature solid-phase reaction method, carbothermal reduction method, as well as hydrothermal method uas tseem tsis tau scaled, spray pyrolysis method, sol -gel method, co-precipitation method thiab lwm yam.

 

1.High-kub khoom-theem tshuaj tiv thaiv txoj kev

 

High-temperature solid-phase reaction method yog txoj kev paub tab thiab siv dav rau kev npaj lithium hlau phosphate (Lifepo4 Powder). Cov khoom siv hlau, lithium qhov chaw, phosphorus qhov chaw raws li qhov sib piv stoichiometric ntawm homogeneous sib tov thiab ziab, nyob rau hauv ib qho chaw inert, thawj ntawm qhov kub thiab txias (300 ~ 350 degree) nyob rau hauv sintering ntawm 5 ~ 10h, kom cov khoom siv raw. ua ntej decomposition, thiab tom qab ntawd nyob rau hauv qhov kub siab (600 ~ 800 degree) nyob rau hauv lub sintering ntawm 10 ~ 20h kom tau olivine hom lithium hlau phosphate.

High-temperature solid-phase method of synthesizing lithium iron phosphate process yog qhov yooj yim, cov txheej txheem kev npaj tau yooj yim los tswj, qhov tsis zoo yog qhov loj me me, qhov loj me me tsis yooj yim los tswj, kev faib khoom tsis sib xws, morphology yog qhov tsis sib xws, cov khoom sib piv cov yam ntxwv tsis zoo.

 

2. Carbon thermal txo txoj kev

 

Cov pa roj carbon thermal txo txoj kev yog ntxiv cov pa roj carbon monoxide (cov hmoov txhuv nplej siab, sucrose, thiab lwm yam) hauv cov khoom siv raw sib xyaw ua tus neeg sawv cev txo qis, feem ntau yog siv ua ke nrog cov txheej txheem kub kub, cov pa roj carbon monoxide hauv kub calcination tuaj yeem txo mus rau Fe {{ 0}} rau Fe2+, zam cov txheej txheem tshuaj tiv thaiv ntawm Fe2+ rau hauv Fe3+, kom cov txheej txheem synthesis yog tsim nyog, tab sis lub sij hawm cov tshuaj tiv thaiv yog ntev dua, kev tswj ntawm cov xwm txheej yog nruj dua.

 

3. Txau pyrolysis

Txau pyrolysis yog ib qho txiaj ntsig zoo ntawm kev tau txais lithium hlau phosphate hmoov nrog cov khoom me me thiab cov duab tsis tu ncua. Lub precursor yog txau nrog cov cab cab rau hauv lub reactor ntawm 450 ~ 650 degree, thiab lithium hlau phosphate tau txais tom qab kub cov tshuaj tiv thaiv. Lub precursor npaj los ntawm cov tshuaj tsuag pyrolysis txoj kev muaj ib tug high degree ntawm sphericity ntawm cov tee dej thiab uniform particle loj faib, thiab tom qab high-temperature cov tshuaj tiv thaiv yuav tau txais spherical lithium hlau phosphate. Cov duab kheej kheej ntawm lithium hlau phosphate yog qhov tsim nyog rau kev nce qhov chaw tshwj xeeb ntawm cov khoom siv thiab txhim kho lub zog tshwj xeeb ntawm cov khoom.

 

4. Hydrothermal txoj kev

Hydrothermal txoj kev belongs rau cov theem ua kua hluavtaws hluavtaws nrog cov dej khov, los ntawm cov tshuaj tiv thaiv cov tshuaj lom neeg, los ntawm kev lim dej, ntxuav, ntxuav kom tau txais cov nano- precursor, thiab thaum kawg tom qab high-kub calcination yuav tau tom qab lithium hlau phosphate. Hydrothermal kev npaj ntawm lithium hlau phosphate muaj qhov zoo ntawm kev yooj yim los tswj cov khoom siv lead ua thiab qhov loj me, lub cev theem homogeneity, me me hmoov particle loj, txheej txheem simplicity, thiab lwm yam, tab sis yuav tsum tau kub thiab siab siab cov cuab yeej, tus nqi siab, cov txheej txheem kuj yog. complex.

 

Ntxiv rau cov txheej txheem saum toj no, muaj cov txheej txheem nag lossis daus, sol-gel txoj kev, oxidation-txo txoj kev, emulsification drying method, microwave sintering method thiab lwm yam.
