Kev rhuav tshem thiab kev hloov pauv yog tus yuam sij
Nyob rau hauv ib txwm muaj xwm txheej, yog tias kev ua haujlwm muaj peev xwm poob qis dua 30%, lub roj teeb hluav taws xob tsis tuaj yeem siv tau rau hauv cascades thiab tsuas tuaj yeem rhuav tshem thiab pov tseg. Tom qab cov roj teeb raug rhuav tshem, cov khoom siv muaj nuj nqis ntxiv xws li cobalt, lithium, npib tsib xee thiab lwm yam khoom muaj nqis tuaj yeem nrhiav tau rov qab. Cov peev txheej no yuav hloov mus ua cov khoom siv rau cov roj teeb. Qhov no yog qhov kawg thiab tseem ceeb tshaj qhov txuas hauv kev tsim cov khoom siv rov qab rau tag nrho lub neej kev lag luam tus nqi txuas ntawm cov roj teeb hluav taws xob.
Nws to taub tias txoj kev rhuav tshem cov roj teeb hluav taws xob muaj peev xwm raug faib ua lub cev rhuav tshem thiab tshuaj tua kab mob. Vim tias cov kua qaub ua kom lub zog thiab cov hauv paus hauv kev siv tshuaj khes mis tuaj yeem ua rau muaj kuab paug thiab ua rau ib puag ncig, Jiangsu xeev tsis txhawb txoj kev no.
Lub tuam txhab ua hluav taws xob tshiab hauv Jiangsu tau tsim cov txheej txheem plasma dismantling, uas siv cov plasma sib cais, cov khoom sib cais sib cais, thiab cov roj tsis muaj kev kho mob ntawm cov roj ntsha lithium roj teeb kom muaj cov peev txheej tshiab. Nws tau tshaj tawm tias hom tshiab ntawm kev rhuav tshem no tuaj yeem tiv thaiv kev siv cov acids thiab alkalis thiab tiv thaiv kev puas tsuaj ntawm ib puag ncig. Tam sim no, cov thev naus laus zis tshiab no tau txhawb nqa hauv lub xeev, thiab qhov haujlwm nrog kev ua txhua xyoo muaj peev xwm ntawm 10,000 tons yuav muab tso rau hauv kev tsim khoom thaum ib nrab xyoo 2020.
Ntxiv rau qhov muaj kuab paug uas tshwm sim los ntawm cov txheej txheem dej tsis sib haum, cov nqi siab kuj tseem yog cov teeb meem uas cuam tshuam rov ua dua tshiab ntawm cov roj teeb uas tsis ua haujlwm. Raws li tus neeg tswj hwm lub tuam txhab muaj feem cuam tshuam, lub tuam txhab siv cov roj ntsha lithium iron phosphate muaj cov nqi hluav taws xob tsawg dua thiab cov khoom siv pov tseg siab, thiab cov nyiaj tau rov qab los kuj tsawg dua li nws cov nqi tsim nqi, uas cuam tshuam loj heev rau cov tuam txhab rov ua dua tshiab.
Tseem muaj ntau qhov kev sib tham ntawm kev lag luam muaj txiaj ntsig ntawm kev rov ua dua tshiab ntawm lub roj teeb hluav taws xob tom qab tshem tawm. Wang Zidong, tus thawj coj ntawm National 863 Lub Tsheb Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Cov Hluav Taws Xob Tshwj Xeeb Lub Zog Hluav Taws Xob tau taw qhia tias seb lub roj teeb hluav taws xob muaj cov nqi ntawm kev rov ua dua yuav tsum txiav txim siab ua ntej los ntawm kev soj ntsuam cov txiaj ntsig ntawm kev siv ntau qib ntawm roj teeb. Hauv kev siv tswv yim, kev rov ua dua tshiab tus nqi ntawm ntau cov ntaub ntawv yog tus nqi tsawg, tshwj xeeb tshaj yog daim ntawv thov ntawm lub tshuab teeb pom kev zoo, ua rau ntau lub tuam txhab siv cov khoom siv hlau tsis zoo rau cov thawv roj teeb, uas muaj tus nqi qis dua. Rau cov roj teeb xws li lithium iron phosphate, tus nqi rov qab ntawm cov khoom siv cathode tsis loj, thiab kev rov qab ua raws li cov txheej txheem ib txwm yuav tsis tsim nyog poob.
Hauv Chen Ping qhov kev pom, "kev tswj hwm kev tswj hwm pov tseg cov roj teeb hluav taws xob rau lub zog hluav taws xob tshiab tom qab cov tsheb so tsis ua haujlwm yog qhov txuas tseem ceeb hauv lub neej ntawm lub neej tag nrho ntawm cov roj teeb hluav taws xob." Yog li, "txheej txheem tswj kev siv rov qab" tau tsim muaj nyob rau hauv lub teb chaws kev tswj hwm txoj haujlwm rau kev rov ua haujlwm ntawm cov tsheb uas raug rho tawm. Dismantling tuam txhab, cov tuam txhab siv khoom siv ua haujlwm, thiab cov tuam txhab rov ua tiav cov ntaub ntawv sau tiav kom tau txais kev soj ntsuam online ntawm lub roj teeb hluav taws xob thiab kev siv lub luag haujlwm ntawm txhua lub koomhaum.
Tam sim no, ib pawg Suav lag luam sawv cev los ntawm Hubei GEM, Beijing Sedmei, Ganzhou Highpower, Hunan Bangpu, Guangdong Guanghua, thiab lwm yam tau pib tsim qee qhov teev tseg ntawm cov khib nyiab hluav taws xob roj teeb rov ua dua tshiab lub peev xwm. Nyob rau tib lub sijhawm, Ningde Times, Guoxuan High-Tech, BYD thiab lwm lub chaw tsim hluav taws xob roj teeb hluav taws xob thiab cov tuam txhab cov khoom lag luam kuj tau npaj rau hauv kev ua haujlwm ntawm cov roj teeb hluav taws xob rov ua dua tshiab. Nyob rau hauv lub neej yav tom ntej, Tuam Tshoj yuav txuas ntxiv mus rau theem kev cog qoob loo ntawm kev lag luam kev lag luam rau lub zog siv roj teeb, thiab txuas ntxiv mus tshawb txog kev ua lag luam muaj ntau cov qauv siv nrog kev siv tshuab ruaj khov, kev paub tab, kev ua lag luam, thiab ib puag ncig kev phooj ywg.
