Kev ua lag luam siv cascade yuav dhau los ua qhov tseem ceeb hauv kev ua haujlwm ntawm lub zog lithium roj teeb rov ua dua tshiab
Since 2018, the first domestic automotive power batteries to enter the market have begun to usher in a "scraping tide". Data shows that in 2018, the scrap recycling of power batteries will reach 63,900 tons, a year-on-year increase of 129.99 percent ; by 2020, the recycling volume will reach 247,600 tons, and the recycling market will be a tens of billions of scale industries in the future.
Under the tuyere of recycling, there is controversy over whether to recycle or dismantle retired batteries. In view of the fact that there are still many problems in cascade utilization, some voices in the industry even call it a "pseudo proposition". In theory, the cascade utilization of retired batteries can achieve maximum use value and economic benefits. Generally, the service life of power batteries is 5 to 8 years. When the battery capacity decays below 80 percent , it cannot meet the needs of electric vehicles. However, after testing, maintenance, and reorganization, the retired batteries can be used in cascade in the fields of energy storage, distributed photovoltaic power generation, household electricity, and low-speed electric vehicles.
Tam sim no, lub hwj chim roj teeb uas tau nkag mus rau hauv kev siv echelon tau mus txog qhov kev pab cuam lub neej ntawm 2, 000 zaug, thiab nws cov kev ua tau zoo nyob rau hauv lub teb ntawm lub zog cia yog zoo dua li cov hlau lead - cov roj teeb carbon. Hauv kev nthuav qhia logistics, kev siv cov roj teeb cascade tuaj yeem txo tus nqi ntawm kev siv ib nrab. Hauv kev ua haujlwm ntawm qis- tsheb hluav taws xob ceev, kev siv cov roj teeb lithium cascade muaj qhov zoo ntawm lub neej voj voog ntev thiab muaj zog dua li cov hlau lead- cov roj teeb acid.
Cov ntaub ntawv kev lag luam qhia tau hais tias qhov ntsuas ntawm kev lag luam siv cascade hauv 2018 yuav ncav cuag 898 lab yuan, thaum lub lag luam loj ntawm kev rov ua dua thiab rhuav tshem yuav yog 319 lab. Los ntawm qhov sib piv ntawm qhov pom, kev siv cascade yav tom ntej yuav yog qhov tseem ceeb, tab sis tsuas muaj qee qhov me me ntawm kev siv cascade ua qauv qhia. Tseem muaj tsawg heev lag luam uas siv cov industrialization ntawm cascade siv.
Nrog rau kev nce nqi ntawm cov khoom siv raw khoom thiab cov nqi nce siab ntawm cov tuam txhab roj teeb, nws yog ib qho tseem ceeb uas yuav tsum tau siv cov roj teeb fais fab hauv cascade kom siv tau cov peev txheej ntau tshaj plaws. Txawm hais tias tseem muaj ntau yam teeb meem, nyob rau hauv qhov xwm txheej ntawm cov cai zoo thiab kev loj hlob ntawm kev lag luam dav dav, kev siv cov roj teeb hluav taws xob cascade yuav tsis nyob deb dhau los ntawm kev ua lag luam tawm.
