Yog hais tias 2014 yog kuv lub teb chaws lub zog tshiab tsheb nyob rau hauv thawj xyoo ntawm Tuam Tshoj, lub 2015 yog kiag li tshiab zog tsheb tawm. Raws li cov ntaub ntawv ntawm Ministry of Industry thiab Information Technology, Lub Kaum Hli 2015, kuv lub teb chaws tau tsim 50,700 lub zog tshiab, 8 npaug ntau dua li xyoo dhau los. Yog tias cov ntaub ntawv tsim tawm thaum Lub Kaum Hli tom qab ntawd, lub zog tshiab lub tsheb yuav raug xa tawm mus rau ntau dua 300,000 lub zog tshiab hauv xyoo 2015.

Nrog rau kev nce hauv lub zog tshiab tsheb, qhov teeb meem rov qab los ntawm cov roj teeb lithium-ion dynamic yog ib txwm tshwm sim. Puzzle 1: Qhov twg yuav tsum tsis txhob siv dua? Tus kws sau ntawv tau ua haujlwm ntawm lub rooj sib tham tshiab ntawm kev lag luam automotive kev lag luam hauv lub Kaum Ib Hlis xyoo tas los los saib seb yuav ua li cas thiaj li rov siv tau cov roj teeb lithium-ion? Cov lus teb yog: tam sim no xav txog kev zam. Raws li tus kws tshaj lij txoj kev xav, tus naj npawb ntawm cov tsheb tshiab lub zog nyob rau lub sijhawm tsis muaj ntau.

Lub dynamic lithium-ion roj teeb technology tsis paub tab. Lub hwj chim lithium-ion roj teeb tshem tawm yog qhov pib xa rov qab mus rau cov chaw tshawb fawb rau kev tshawb fawb, yog li tsis tas yuav xav txog qhov loj-loj rov ua dua tshiab. Niaj hnub no, ib lub hlis ntawm cov khoom siv hluav taws xob tshiab nyob rau lub Kaum Hlis tau tshaj li ib nrab ntawm cov khoom tsim tawm xyoo tas los (2014 lub zog tshiab lub tsheb txhua xyoo ntawm 83,900), thiab nrog rau txoj cai kom zoo dua thiab kev txuas ntxiv mus rau txhua qhov kev txhawb nqa hauv zos, cov tsheb tshiab lub zog kev ruaj ntseg kuj tseem yuav nce ntxiv, cov roj teeb lithium-ion loj yuav ntsib teeb meem rov qab los.

According to my country Automobile Technology Research Center, by 2020, my country's electric vehicle power lithium-ion battery accumulated scrap volume will reach 120,000 to 170,000 tons. In the recent "my country's new energy vehicle promotion application related experience exchange and development seminar", Wang Bing, director of the national 863 energy-saving and new energy automobile project supervision consulting expert group also said that with the large scale of the power lithium-ion battery Adincinal, the work of battery recycling should also be layout and start as soon as possible. Nws tuaj yeem pom tias qhov teeb meem ntawm kev rov ua dua tshiab ntawm cov roj teeb lithium-ion dynamic tau dhau los ua ib qho teeb meem uas peb yuav tsum tau ntsib.

Puzzle 2: Who is responsible for recycling? At present, the industry and some of the public regarding whether the dynamic lithium-ion battery has tended to be consistent, then who should be responsible for recycling behavior? On September 11, the National Development and Reform Commission and the Ministry of Industry and Information Technology jointly announced that "the relevant electric vehicle power storage battery recycling technology policy (2015 version)" is clear, it is clear that the automotive manufacturer will become the main body of the electric vehicle used power storage battery recycling. But how much is this implementation? In the production and consumption of new energy vehicle power lithium-ion batteries, battery production companies, vehicle companies, and consumers will be involved. Lub tuam txhab tsim cov roj teeb yog lub luag haujlwm rau kev tsim cov roj teeb thiab cov tshuab muaj feem xyuam, thiab sib sau ua ke raws li cov kev xav tau ntawm cov tuam txhab tsheb;.

Kev kho cov roj teeb lithium ion pov tseg yuav raug tshem tawm, tshem tawm, pulverized, txheeb xyuas, rov qab hauv tsev, acid-base extraction, thiab lwm yam., nws cov kev tshaj lij tsis yog lub tuam txhab tsim cov lithium ion uas twb muaj lawm thiab lub tuam txhab tsheb unilaterally ua tiav. Muaj cov kws tshaj lij tau hais tias nyob rau hauv qhov kev pom ntawm cov txheej txheem nyuaj rau cov txheej txheem dynamic lithium-ion roj teeb rov qab, nws yog qhov zoo tshaj plaws kom rov qab tau cov roj teeb rov qab zoo dua.

The expert said that electric vehicles reported that lithium-ion battery recycling and reuse is a new line, whether it is a vehicle-enterprise or battery company, will face many challenges. For battery material production companies, due to the similar technical route, the future may occupy the first machine. Puzzle 3: How to reclaim? Although battery manufacturers can occupy a certain advantage in power lithium-ion battery recovery, and has already involved this business, because there is currently no relevant related experience, power lithium ion battery recycling Undoubtedly still "unknown blue sea".

Yuav ua li cas cov qauv yuav ua raws li cov txheej txheem rov qab, thiab nws tseem tsis tau paub txog tus lej. There have been media that there is currently a new energy vehicle power lithium-ion battery to recover national standards. The relevant departments have organized new energy automotive companies, experts, etc.

to discuss the discussion of 2-3 rounds, discussion focused on the cost of fees in the battery recovery process. Battery production company believes that power lithium-ion batteries are sold to vehicle companies, and the cost of battery recovery should be responsible by the vehicle company; the vehicle company believes that the battery is used by consumers, the recycling cost should be co-carried by the vehicle company and consumers. Bell; while consumers believe that the battery purchased by the battery is recycled, the vehicle company and battery manufacturers should make up for this part of the loss.

Yuav ua li cas sib npaug ntawm cov cai ntawm tog neeg tiag tiag, thiab qhov teeb meem uas yuav tsum tau ua tib zoo txiav txim siab los ntawm lub tuam tsev txiav txim siab. In addition, my country has not introduced the corresponding power lithium-ion battery recycling mechanism. The general method currently adopted is to take the recovery method of nickel-hydrogen, nickel-cadmium and lithium-ion batteries similar to consumer electronics, and extract valuable metals.

This form can solve the problem of dynamic lithium-ion battery recovery in the case where the new energy vehicle has a small amount, but does this method still will be discussed when the number of resilient lithium-ion batteries has increased significantly. Muaj qee qhov kev xav tias nws yuav yog ib txoj hauv kev zoo los daws qhov rov siv dua ntawm kev daws teeb meem dynamic lithium-ion roj teeb. Tsheb loj heev Daimler - Mercedes-Benz tsis ntev los no tau tshaj tawm ob txhais tes roj teeb lub zog cia khoom nrog lub peev xwm ntawm 13 megawatts thiab ntau lub tuam txhab.

However, there are also experts, and different vehicle manufacturers are supplied by different battery production companies, while different models of the same vehicle company may also use different models of power lithium-ion batteries, which will cause energy storage batteries in terms of consistency. Serious problem. Therefore, there is an industry insiders to solve the consistency problem of the recycling phase from the decision-making department to formulate the corresponding unified standards from the dynamic lithium-ion battery production stage.

Puzzle 4: Tus qauv siv li cas? Txij li thaum nws tseem yog "xiav hiav txwv", dab tsi qauv yog siv rau lub hwj chim lithium-ion roj teeb rov qab, thiab cov tuam txhab loj tam sim no nyob rau theem tshawb nrhiav. Daimler - Mercedes-Benz rov qab tau lub lithium-ion roj teeb lub zog cia qhov project lossis yuav muab tso rau hauv kev ua haujlwm hauv 2016, txawm hais tias nws tsuas yog yuav tsum tau coj tsuas yog Mercedes-Benz hluav taws xob tsheb tsis paub, qhov no tej zaum yuav yog lub tsheb lag luam rau lub zog lithium-ion roj teeb rov ua dua Ib qho ntawm qhov ua tiav ntawm kev rov siv dua. In addition, there is also a business model of battery production companies and professional recycling companies to find.

As recent battery production company, BYD collaborates with Lithium-ion battery recycling company Greenmei, hoping to achieve a win-win situation in the field of power lithium-ion battery recycling through promotion, operation and operation of energy storage power stations and photovoltaic power plant projects. Kuj tseem muaj cov tuam txhab tsim khoom siv roj teeb los muab cov khoom siv sab hauv, xws li Watma los tsim cov roj teeb lithium-ion rov ua dua tshiab tom qab kuaj kev nyab xeeb, tsim lub chaw nres tsheb fais fab, tso tawm thaum nruab hnub, them nyiaj thaum hmo ntuj, tiv thaiv hluav taws xob xav tau rau lub Hoobkas nruab hnub, txo lub tuam txhab hluav taws xob ib feem ntawm cov nqi siv. Tsis tas li ntawd, kuj tseem muaj cov kev lag luam sab hauv uas tuaj yeem siv rau hauv hluav taws xob tricycles, ob lub log, lub zog thaub qab, lub zog cia roj teeb, lossis cov khoom siv hlau raws li cov xwm txheej sib txawv ntawm cov khoom siv hluav taws xob lithium-ion roj teeb, thiab tuaj yeem siv rau cov khoom hlau, uas tuaj yeem ncav cuag lub hom phiaj.

Regardless of the business model, experts recommend not to be too dispersed with the company's main business, otherwise it will not be able to obtain higher economic benefits. Tsis tas li ntawd, txhawm rau txhim kho kev rov qab ua haujlwm ntawm lub zog hluav taws xob lithium-ion roj teeb, tsim kev lag luam, nws yog ib qho tsim nyog yuav tsum tsim kom muaj qhov chaw rov qab tshwj xeeb, thiab qhov chaw rov ua dua yuav tsum nyob deb ntawm lub nroog nruab nrab thiab yuav tsum tsis txhob ntau dhau los tiv thaiv lub roj teeb lithium-ion. Ib puag ncig muaj kuab paug.

Nyob rau tib lub sijhawm, lub tuam txhab yuav tsum tau rov ua dua los ntawm lub tuam txhab, thiab "kev tsis sib haum xeeb" lub xeev nyob rau yav dhau los cov roj teeb rov qab txuas tau raug tiv thaiv los ntawm kev tiv thaiv lub roj teeb "thawj kev ua qias tuaj".
