Rov qab cov yam ntxwv ntawm lithium hlau phosphate roj teeb

Kev loj hlob sai thiab loj seem ntim
Txij li thaum txoj kev loj hlob ntawm kev lag luam tsheb hluav taws xob, Tuam Tshoj tau yog lub ntiaj teb cov neeg siv khoom lag luam loj tshaj plaws rau lithium hlau phosphate. Tshwj xeeb los ntawm 2012 txog 2013, nws loj hlob ntawm tus nqi ze li ntawm 200 feem pua. Hauv xyoo 2013, kev muag khoom ntawm lithium hlau phosphate hauv Suav teb yog kwv yees li 5797t, suav txog ntau dua 50 feem pua ​​​​ntawm kev muag khoom thoob ntiaj teb.
Hauv xyoo 2014, 75 feem pua ​​​​ntawm cov khoom siv lithium hlau phosphate cathode tau muag rau Suav teb. Lub neej theoretical ntawm lithium hlau phosphate roj teeb yog 7 mus rau 8 xyoo (xws li 7 xyoo). Nws tau kwv yees tias kwv yees li 9400 tons ntawm lithium hlau phosphate yuav raug muab pov tseg los ntawm 2021. Yog tias cov khib nyiab loj npaum li no tsis raug kho, nws yuav tsis tsuas yog ua rau muaj kuab paug ib puag ncig, tab sis kuj muaj hluav taws xob pov tseg thiab kev lag luam poob.
Teeb meem loj
Cov tshuaj lom neeg xws li LiPF6, organic carbonate thiab tooj liab muaj nyob rau hauv lithium hlau phosphate roj teeb tau suav nrog hauv daim ntawv teev cov khib nyiab pov tseg hauv lub tebchaws. LiPF6 muaj zog corrosiveness thiab nquag decompose rau hauv HF thaum raug dej; Cov kuab tshuaj organic thiab lawv cov khoom decomposition thiab hydrolysis tuaj yeem ua rau muaj kuab paug loj rau huab cua, dej, thiab av, thiab ua rau muaj kev hem thawj rau ecosystems; Cov hlau hnyav xws li tooj liab sib sau ua ke nyob rau hauv ib puag ncig thiab thaum kawg ua mob rau tib neeg los ntawm cov saw hlau; Thaum phosphorus nkag mus rau hauv pas dej thiab lwm lub cev dej, nws muaj peev xwm ua rau eutrophication. Nws tuaj yeem pom tias yog tias cov roj teeb lithium hlau phosphate pov tseg tsis rov siv dua, nws yuav ua rau muaj kev puas tsuaj loj rau ib puag ncig thiab tib neeg kev noj qab haus huv.
