According to the statistics of China and Automobile Association, in the first half of 2016, my country's new energy auto production was 177,000, 170,000, and my country is still the world's largest new energy car market. However, with the outbreak of the new energy car market, my country's positive problems with the driving lithium-ion battery recovery. Power Lithium Ion Battery Scrap Surgreatment Belt Potential Threat Electric Vehicle Power Lithium Ion Battery is usually 5-8 years, and it is expected that my country will usher in the first batch of power lithium-ion batteries "retire" next year.
The battery has found in the industry data of the investigation. With the rapid development of the new energy vehicle industry, by 2020, my country's powered lithium-ion battery will reach 32.2GWH, about 500,000 tons; to 2023, the waste volume will Reach 101GWH, about 1.
16 million tons. Accompanied with a large-scale power lithium battery market, it is a rapid rise in power lithium-ion battery scrap, a large number of scrapped dynamic lithium-ion batteries threaten the natural environment, national health and society sustainable development. We cannot ignore the potential harm brought by the abandoned power lithium-ion battery.
Battery positive metal ions, carbon dust, strong bases and heavy metal ions in the electrolyte, once entered into the environment, will increase the pH of the soil, and may have poisonous gases, causing serious environmental pollution. The internal metal and electrolyte will also endanger human health, such as cobalt elements, can lead to symptoms such as intestinal disorders, deafness, myocardial ischemia. The new energy vehicle has the advantage of "reducing waste gas pollution, responding to fossil energy shortage", if environmental pollution is caused by the scrapped dynamic lithium-ion battery, affecting national health, will be contrary to the original intention of developing new energy vehicles.
However, my country is still facing a series of tricky problems in the recovery and processing of the radical lithium-ion battery. The power lithium-ion battery recovery is so difficult for the powerful lithium-ion battery. The recycling industry has not yet been established.
This has the complex factors of the battery itself, and there is also a factor in policy supervision. According to the battery my country Network analysis, the powerful lithium-ion battery recycling is difficult to reflect in the following aspects: 1. Power lithium-ion battery has a poor economy, lack of profit points.
The cost of recycling of dynamic lithium-ion batteries is high, and the economic value is not good, lacks a profit point. This is an important reason for the unspecite of my country's dynamic lithium-ion battery. According to the survey, a company with mechanical law and wet recovery of iron-free phosphate ion batteries, recycling 1 ton waste phosphate dynamic lithium-ion battery is 8540 yuan, while the regeneration material is only 8110 yuan, loss 430 Yuan.
Due to the lack of profit points, the market main body recycling battery is insufficient, after all, there is no "live Lei Feng" in the market economy, and no one is willing to do the sale of money. 2. Abandoned dynamic lithium-ion battery is complex, dismantling is inconvenient.
my country's powered lithium-ion battery production lacks unified industry standards, different types of batteries, manufacturing and design processes, and string and combined group forms, service and use time, application models and use conditions have different cases, this is dismantled for battery The solution has a great inconvenience, adding a handling cost. 3. Waste dynamic lithium-ion battery is not high.
Re-use of the scrapped dynamic lithium ion battery, quality testing of safety assessment, cycle life test, etc. If the power lithium-ion battery lacks a complete data record during the first service, when the secondary useful life prediction, the accuracy will deviate, and the battery consistency cannot be guaranteed. In addition, if there is a problem, the battery is not detected, the entire battery system will face huge security risks.
4. Power Lithium Ion Battery Recycling: Who will pay? First, the scrapped power lithium-ion battery should be recycled. The "Electric Automotive Battery Recycling Technology Policy (2015)" jointly announced by the National Development and Reform Commission and the Ministry of Industry and Information Technology this year, clear the main body of the powerful lithium-ion battery recycling - electric vehicle production company, power battery production company, step-by-battery Production company, scrapped car recycling dismantling company, these four companies should bear different responsibilities.
After the responsibility is clear, who will bear high recycling costs? Battery production companies believe that the vehicle is responsible; the vehicle consumes to be borne by the vehicle company and consumers; while consumers think that they buy batteries are recycled. , Vehicle companies and battery manufacturers should make up for this part of the loss. Do not undertake the recovery fee, the battery is still unable to recover.
This is to balance the interests between the whole vehicle, battery manufacturers and consumers, and there must be feasible business models to promote power lithium-ion battery recycling. The national standard introduced the powerful lithium-ion battery recycling is expected to regulate the new energy vehicle power lithium-ion battery bulky, complex structure, and in the process of recovery, if the dismantling operation is improper, it is easy to cause electrolyte leakage, short circuit and even explodes. Therefore, the general technical requirements, operation procedures, dismantling methods, and storage management of dynamic lithium-ion batteries are urgently needed to have a unified operational specification.
In addition, power lithium-ion battery recovery has not yet established effective recycling modes, scrapped batteries or non-professional recycling institutions such as individual private, retailers, automotive repair shops, and 4S stores, which not only cause waste, environmental pollution, etc. Improper treatment will seriously endanger the safety. In January 2016, my country's first new energy vehicle dynamic lithium-ion battery recovery national standard - "Conditional Decomposition of Velive Lithium Ion Battery Recovery and Utilization" and "Energy Detection of Car Power Lithium Ion Battery Recycling".
This means that my country's powered lithium-ion battery recycling is about to open standardization, standardized big curtains, natural environment, national health and social and economic sustainable development will also get better guarantees. Dynamic lithium-ion battery recovery, although the dynamic lithium-ion battery recovery has not yet realized industrialization, there are still some useful attempts to learn from. my country's latest news, Henan Electric Power Company Electric Science Research Institute successfully designed and built the first 5,000 tons / year based on dry automatic dynamic lithium-ion battery recycling production line, achieving efficient and environmentally friendly recovery processing of dynamic lithium-ion batteries.
The production line abandoned the traditional fire, wet method and other high energy consumption, high pollution recovery treatment technology, after more than a year of hard innovation and repeated trials, 10,000 kilograms of scrapped batteries per hour, the annual processing volume reached 5,000 tons, the waste lithium ion The battery price component is more than 90%, and the recovery efficiency is high, energy saving and environmental protection, no secondary pollution. The production line realizes the circular utilization of battery materials, and it is expected to solve the "bottleneck" and "worries" and "worries" of energy storage and new energy vehicles. Through continuous exploration and attempts, my country's dynamic lithium-ion battery recycling field has made certain progress.
There is reason to believe that under the joint efforts of decision-making departments, research institutions, and industry, we will finally establish and improve the dynamic lithium-ion battery recovery system, form an effective multi-partial cooperative recycling model and a perfect power lithium-ion battery recycling industry chain, then Power lithium-ion battery recovery will no longer be a "difficult bone". .
