1.Kev loj hlob sai, ntau ntawm cov khoom seem
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 brttery. Tshwj xeeb, nws tau loj hlob ntawm tus nqi ze li ntawm 200 feem pua ntawm 2012 txog 2013. Hauv 2013, qhov muag ntim 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 7-8 xyoo (xws li 7 xyoo). Nws cia siab tias kwv yees li 9,400 tons ntawm lithium hlau phosphate yuav raug muab pov tseg los ntawm 2021. Yog tias cov khib nyiab loj heev 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.
2. Kev puas tsuaj loj heev
LiPF6, organic carbonate, tooj liab thiab lwm yam tshuaj lom neeg muaj nyob hauv lithium hlau phosphate roj teeb yog tag nrho suav nrog hauv daim ntawv teev cov pov tseg pov tseg hauv lub tebchaws. LiPF6 yog corrosive heev thiab yooj yim decomposes los tsim HF thaum raug dej; organic solvents thiab lawv decomposition thiab hydrolysis cov khoom yuav ua rau muaj kuab paug loj rau huab cua, dej, thiab av, thiab ua phem rau lub ecosystem; hnyav hlau xws li tooj liab nyob rau hauv ib puag ncig thiab nws thiaj li ua mob rau tib neeg lawv tus kheej los ntawm cov kab mob lom; ib zaug phosphorus nkag mus rau hauv pas dej thiab lwm lub cev dej, nws yooj yim heev los ua 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 phom sij heev rau ib puag ncig thiab tib neeg kev noj qab haus huv.
3.Imature recycling technology
Cov ntaub ntawv uas twb muaj lawm qhia tias muaj ob hom kev rov ua dua tshiab rau cov khib nyiab lithium hlau phosphate roj teeb: ib qho yog cov khoom siv rov ua dua tshiab, thiab lwm qhov yog cov khoom siv lithium hlau phosphate cathode.
