Raws li cov ntaub ntawv tso tawm los ntawm kuv lub teb chaws Automobile Industry Association, nyob rau hauv thawj ib nrab ntawm lub xyoo, kuv lub teb chaws lub zog tshiab tsheb tau sau 1206,000 units, nce 201.5% xyoo-rau-xyoo. Cov tsheb tshiab lub zog tawg txhawb cov khoom tseem ceeb - tsim cov roj teeb lithium-ion dynamic.

Nyob rau hauv thawj ib nrab ntawm lub xyoo, kuv lub teb chaws lub hwj chim lithium-ion roj teeb ntau lawm sau 74.7GWH, ib xyoo-rau-xyoo nce ntawm 217.5%.

Tom qab cov ntaub ntawv ci tau muab zais rau hauv qhov teeb meem: muaj pes tsawg lub zog lithium-ion roj teeb muaj ntau lub roj teeb rau "tso tawm", tab sis lub zog hluav taws xob lithium-ion roj teeb rov ua lag luam tsis yog tus qauv txaus, thiab cov txheej txheem rov ua dua tsis zoo tag nrho, muaj kev ruaj ntseg ib puag ncig kev nyab xeeb. Lub zog tshiab tsheb pib xyoo 2014 kom nrov hauv Suav teb, thiab lawv lub zog lithium-ion roj teeb lub neej nyob ib puag ncig 8 xyoo. Raws li kev lag luam cov ntaub ntawv txheeb cais, tag nrho cov nyiaj ntawm "nyiaj laus" hauv kuv lub teb chaws lub zog lithium-ion roj teeb yog li 200,000 tons; nyob rau hauv 2022, nws xav tias yuav muaj 420,000 tons ntawm lub zog lithium-ion roj teeb "tso tawm"; Xyoo 2025, tus lej no yuav tsum nce mus rau 780,000 Tuj.

Nyob rau hauv lub ntsej muag ntawm lub zog lithium-ion roj teeb uas yuav los tom ntej no "nyiaj laus" cov dej ntws, cov neeg sab hauv tau taw qhia tias kev rov ua dua tshiab ntawm cov roj teeb lithium-ion yuav tsum tau txhim kho, kev siv ntaiv thiab cov khoom siv rov ua dua tshiab yuav tsum tiv thaiv lub nraub qaum ntawm lub zog tshiab. Ntawm qhov tod tes, kuv lub teb chaws lub zog tshiab tsheb tsim thiab kev muag khoom txuas ntxiv nyob rau hauv rau xyoo, thiab lub tsheb tsim muaj peev xwm thiab lub zog ntawm lithium-ion roj teeb ntau lawm, lub zog lithium-ion roj teeb rov qab yog pib xwb. Raws li kev tshaj tawm xov xwm, vim tias cov nqi rov qab siab dua thiab cov nqi ua haujlwm ntawm cov channel raug cai, cov txiaj ntsig kev lag luam tsawg, txog ib nrab ntawm "nyiaj laus" lub zog lithium-ion roj teeb ntws mus rau hauv kev lag luam tsis raws cai los ntawm kev tsis raws cai.

Qhov no yog lub zog muaj zog lithium-ion roj teeb "nyiaj laus" nthwv dej. Ntawm qhov tod tes, lub zog tshiab tsheb tau paub txog ntsuab, ib puag ncig tus phooj ywg thiab txuag hluav taws xob. Txawm li cas los xij, cov roj teeb lithium-ion fais fab tuaj yeem ua rau muaj kuab paug ib puag ncig yog tias cov khoom siv rov ua dua tsis raug.

Thaum lub lithium phosphate ion roj teeb, ib zaug cov electrolyte xau tshwm sim, nws tuaj yeem ua rau muaj kuab lom thiab corrosive electrolyte ntws mus rau hauv ib puag ncig ntuj. Cov hlau hnyav xws li manganese, cobalt, nickel muaj nyob rau hauv peb-dimensional lithium ion roj teeb cov ntaub ntawv yuav ua rau muaj kuab paug rau dej thiab av. Nyob rau tib lub sijhawm, lub zog ntawm lithium-ion roj teeb kev ua tau zoo ntawm cov tsheb tshiab lub zog yog siab, thiab lub peev xwm roj teeb yog attenuated rau ntau tshaj 20%.

Yog li ntawd, ntau lub roj teeb lithium-ion dynamic lithium-ion tseem tuaj yeem siv thiab rov siv dua, thiab lawv yuav ua rau cov khoom pov tseg. Cov pa phem thiab pov tseg yuav ua rau muaj kev puas tsuaj rau lub tsheb tshiab kom muaj kev tiv thaiv ib puag ncig ntau xyoo, cov duab txuag hluav taws xob. Lub zog hluav taws xob lithium-ion roj teeb rov ua dua tshiab yog ib feem tseem ceeb ntawm txoj kev loj hlob ntawm lub zog tshiab tsheb kev lag luam yav tom ntej, thiab nws tseem ceeb heev kom txo qis lub rooj tsav xwm luv luv.

Tam sim no, "tso tawm" lub hwj chim lithium-ion roj teeb rov siv cov ntaiv tseem ceeb thiab rov ua dua tshiab kom rho tawm ob qho kev qhia tseem ceeb ntawm cov khoom siv raw. Tus nqi ntawm cov roj teeb seem yog qhov nyuaj rau kwv yees tias cov nqi hlau hloov pauv cuam tshuam rau cov khoom siv rov qab kev lag luam, kev siv ntaiv tsis muaj cov qauv kev qhia, thiab lwm yam. Qhov tseeb, qib kev tswj hwm feem ntau ua haujlwm hauv dynamic lithium-ion roj teeb rov qab.

Raws li thaum ntxov xyoo 2018, 7 lub tuam tsev ntawm Ministry of Industry thiab Information Technology tau koom ua ke tsim lub zog tshiab lub tsheb fais fab cia roj teeb rov ua haujlwm ua haujlwm. Xyoo no, "Accelerating the Construction of the Power Lithium Ion Battery Recycling System" kuj muaj nyob rau hauv tsoomfwv tsab ntawv ceeb toom. Lub National Development thiab Reform Commission tau tshaj tawm rau Lub Xya Hli 1st "Lub 14th Tsib Xyoo Plan" Circular Economic Development Plan kuj tau dhau los ua ib qho ntawm cov haujlwm tseem ceeb.

Yav tom ntej, cov qauv kev lag luam zoo dua thiab cov kev cai yuav tsum tau pab kev lag luam kom txav mus rau kev loj hlob zoo. Los ntawm kev lag luam pom, lub zog hluav taws xob lithium-ion roj teeb rov ua dua tshiab tseem yog lub hiav txwv xiav, qhov kev loj hlob muaj peev xwm loj heev. Lub koom haum xav tias nyob rau hauv rooj plaub ntawm Tuam Tshoj tus nqi seem, tus nqi ntawm phosphate thiab ion roj teeb ntaiv yuav ncav cuag 68 billion yuan hauv 2020 txog 2030.

2020 ~ 2030 peb-yuan lithium ion roj teeb uas tau txais qhov chaw rov ua dua tshiab yuav ncav cuag 13.5 billion yuan nyob rau hauv rooj plaub. Nws tuaj yeem hais tias cov roj teeb uas muaj zog lithium-ion rov ua dua tshiab yuav tsum tau ua qauv, thiab nws tseem tsim nyog sib sib zog nqus.

Nws yog ib qho tsim nyog los tsim kom muaj lub suab rov ua dua tshiab los pab lub zog tshiab tsheb kev lag luam kev noj qab haus huv. Duab (Source: Worker Daily) / Sau: Du Xin).
