Konstriksyon an nan chanèl pouvwa ityòm batri resiklaj te antre nan yon peryòd kritik, gwo pri ak ekonomi fèb te vin tounen yon pwen doulè nan endistri a.
Pandan ke nouvo endistri machin enèji a ap pwospere ak devlope, pwoblèm nan resiklaj batri pouvwa te vin tou konsantre nan endistri a. Apre plizyè ane nan devlopman, peryòd la mas kraze nan machin enèji nouvo ap apwoche. Si yon gwo kantite pil retrete pa ka byen resikle ak itilize, li pa pral sèlman mennen nan fatra nan resous, men tou, lakòz pwoblèm tankou polisyon nan anviwònman an.
"With the establishment of the production responsibility extension system with vehicle enterprises as the main body, the power battery recycling industry has entered a critical period of channel construction." Huang Jianzhong, former deputy inspector of the Department of Energy Conservation and Comprehensive Utilization of the Ministry of Industry and Information Technology and Secretary General of China Electronics Energy Saving Technology Association On April 17, at the 7th Automotive Power Battery Recycling and Regeneration and Secondary Battery Recycling and Regeneration Technology Seminar, it was stated that the design and production of power batteries in my country and the recycling, disposal and comprehensive utilization of waste power batteries are currently in urgent need of support and regulation. preliminary stage of development.
Pwen doulè endistri: gwo pri, fèb ekonomi
Peryòd pou pran retrèt pou machin nouvo enèji pasaje yo anjeneral 5 ane, ak pou machin pasaje yo ak machin komèsyal li se 3 zan. Anvan 2022, pil retrete yo pral domine pa pil ityòm fosfat fè. Apre 2022, kantite pil retrete ternary yo pral menm jan ak sa yo ki nan ityòm fè fosfat, epi yo pral piti piti depase yo. Kapasite teyorik demantèman pil pouvwa a nan 2018 espere 5.14GWh, ak sous demantèlman se sitou nouvo otobis enèji.
Repòtè a te aprann ke konpayi yo ki te deplwaye biznis ki gen rapò yo sitou divize an senk kategori: konpayi resiklaj tradisyonèl yo, konpayi resiklaj émergentes, faktori pake batri, konpayi materyèl batri ak manifaktirè machin yo.
Diferan kalite biznis gen avantaj ak dezavantaj diferan. Pou egzanp, konpayi resiklaj tradisyonèl yo gen relativman avantaj nan chanèl resiklaj, teknoloji rejenerasyon materyèl, teknoloji kraze batri ak teknoloji SMELTING, men akòz mank pwòp yo nan sous batri pouvwa yo, yo toujou bezwen kolabore ak OEMs ak plant bouyon. Avantaj ki genyen nan konpayi resiklaj émergentes yo sitou reflete nan teknoloji kraze ak demantèlman batri.
Kounye a, metòd tretman pil fatra yo sitou gen ladan teknoloji pyrometallurgie ak teknoloji hydrometallurgie. Wang Haibei, direktè rechèch metaliji ak konsepsyon Enstiti Beijing Mining ak Metaliji Teknoloji Group co, Ltd, te di ke pwosesis la SMELTING nan teknoloji a ki deja egziste se trè konplike ak difisil.
"The smooth operation of the recycling system needs to be based on profit. If there is no profit drive, the enthusiasm of enterprises cannot be fully improved." Wang Haibei said frankly, "The existing investment in recycling technology and the construction of recycling outlets are very large, although many enterprises have deployed Test the water, but few companies have dug a large pot of gold."
It cannot be ignored that toxic electrolytes and harmful gases will be generated during the battery recycling process, which will cause great harm to the environment and human health if not handled properly. "Some companies use high-temperature heating or combustion in the processing process, and the lack of strict control can easily endanger the health of workers." Ming Yuebin, general manager of Harbin Batterui Resource Recycling Technology Co., Ltd. pointed out.
Konpayi Gouvènman yo mete tèt yo ansanm pou chèche zouti
An repons a pwoblèm ki anwo yo, depatman leta enpòtan yo te bay yon seri de politik endistriyèl pou gide ak kontwole endistri resiklaj batri pouvwa a.
In February this year, seven ministries including the Ministry of Industry and Information Technology jointly issued the "Interim Measures for the Administration of Recycling and Utilization of Power Batteries for New Energy Vehicles", clarifying that automobile manufacturers assume the main responsibility for power battery recycling. In March, the Ministry of Industry and Information Technology and other seven ministries and commissions jointly issued the "Notice on Organizing the Pilot Work of Recycling and Utilizing New Energy Vehicle Power Batteries", proposing to select some regions such as Beijing-Tianjin-Hebei, Yangtze River Delta, Pearl River Delta, and central regions to carry out power battery recycling and utilization. The pilot, with the pilot as the center, radiates to the surrounding areas.
"The issuance of the above notice indicates that my country's recycling policy system is gradually being established." Yang Qingyu believes that "with the continuous breakthrough of related technologies, the speed of policy release will be accelerated, and relevant standards are expected to be released this year."
The participants believed that there are considerable differences in the battery type, battery capacity and voltage platform of new energy vehicles at present, which is the first hurdle for the cascade utilization of power batteries. Therefore, how to scientifically evaluate retired batteries has also become a decision on where to go. "The first pass.
"The evaluation process of retired batteries is mainly to upload the collected online and offline data to the monitoring platform at the same time, so as to analyze and process the battery pack and evaluate the performance." Fei, technical director of Beijing Jiangxin Battery Technology Co., Ltd. pointed out that from the evaluation As a result, the value of cascade utilization of ternary batteries is greater than that of direct dismantling.
Dapre rapò, apre batri retrete a te pase evalyasyon an, ka lyen itilizasyon kaskad la pou ede sistèm depo enèji amelyore ekonomi an jeneral ak maksimize lavi sik batri ityòm yo. Kounye a, anpil antrepriz te pote pwojè demonstrasyon itilizasyon kaskad.
Zhang Bu, Vice President of Marketing of Shanghai Xida New Energy Technology Co., Ltd. told reporters: "It was originally predicted that the decay rate of battery cascade utilization was 3 percent -5 percent , but from the actual operation of the project, except for the cold months, most of the battery The discharge data showed no decay, even lower than the decay rate of a new battery."
For the treatment of toxic gases, Ming Yuebin believes that pipeline machinery can be used to crush the batteries and modules as a whole, recover the electrolyte as a whole, and use separation technology to separate materials, positive and negative powders, so as to obtain the final metal casing. "Because the diaphragm is completely recycled, it doesn't turn into a harmful gas," she added.
-Kowoperasyon pwofondè pou polir chèn endistriyèl la
Li konprann ke sistèm resiklaj batri pouvwa a enplike anpil moun ki gen enterè tankou konpayi machin, manifaktirè batri, konpayi resiklaj batri, elatriye chèn lan long, epi toujou gen anpil difikilte nan pwosesis operasyon aktyèl la.
In this regard, Xie Shaozhong, general manager of Jiangxi Ganfeng Recycling Technology Co., Ltd., gave a suggestion: "All links in the industrial chain need to be run in, but the overall principle should be 'professional people do professional things'. For example, auto companies should set up recycling channels, recycling After that, it will be handed over to comprehensive utilization enterprises for professional processing, and all links of the industrial chain will cooperate in depth."
Yo rapòte ke yon kantite konpayi yo te deplwaye resiklaj batri pouvwa nan oseyan ble sa a:
At the end of 2017, BAIC BJEV released the "Optimus Prime Plan": by 2022, it is expected to invest 10 billion yuan to build 3,000 optical storage and replacement power stations across the country, with a total of 500,000 battery-swappable vehicles and echelon energy storage batteries. Utilize more than 5GWh.
Nan mwa janvye 2018, China Tower Corporation ak 16 konpayi ki gen ladan Sound Group te siyen yon akò patenarya estratejik pou resiklaj nouvo pil enèji machin enèji. Konpayi Tower Lachin pral sèvi ak batri pouvwa a pran retrèt nan otobis elektrik pi bon kalite, apre tès, klasman ak reyòganizasyon, ranplase batri a plon -asid pou backup enèji estasyon baz kominikasyon an.
"Both car companies and power battery companies are striving to implement the advanced concept of extended producer responsibility. I hope that all participants can explore the establishment of power battery recycling suitable for the characteristics of industries, enterprises and products from the perspective of undertaking corporate social responsibility. Huang Jianzhong pointed out, "If the finishing touch of the power battery is the cascade utilization and resource disposal, then the establishment of the recycling mode and mechanism will be its magic touch."
