Lithium-ion battery pack recycling market is not ideal, five bottlenecks need to break through. The lithium-ion battery pack is calculated this year to recycle the peak period of recycling, but the recycling and re-use of lithium-ion batteries has not been improved, causing many batteries to waste a lot of recycling resources. How to safely recycle, environmentally friendly, strengthen the standardized circular utilization of waste dynamic lithium batteries, becoming a world-class problem.
Reuse and resource recovery of lithium-ion battery pack will bring huge economic income to the new energy market. my country's powered lithium battery will usher in "reported a waste". By 2020 report will exceed 248,000 tons.
The lithium tram used in my country's new energy vehicles, due to the limitations of technical levels and usage, the effective service life of the design is about 3 years, and the replacement will be replaced after 3 years. In 2018, it is the first year of new energy vehicle lithium-ion battery packs. my country's new energy vehicle power lithium battery will enter large-scale retired stage.
The five bottlenecks encountered by the lithium-ion battery pack: 1. Lithium-ion battery pack recycling mode is uncertain, although it starts, the prospect is generally optimized in the industry. Overall, the large-scale "retired tide" of the current dynamic lithium battery has not arrived, and the power lithium battery dismantling recovery is difficult to form a scale.
For example, some car companies choose to cooperate in the form of cooperation, and join hands to jointly promote the recycling of domestic power lithium batteries. Changan, BYD, Yinlong New Energy and other 16 vehicle and battery companies and powered lithium battery recycling and use large household iron tower companies to reach cooperation, solve the problem of recycling and recycling of retired dynamic lithium batteries. But the overall recovery model has not been determined.
Second, the lack of lithium-ion battery pack recovery main body is in accordance with the principle of cycling and use, and my country's current initiative to use the principle of retirement recycling, and asks the vehicle as a power lithium battery recovery main body. Taken a powerful lithium battery recovery responsibility. However, due to most of the vehicle company is only the "assembly factory" of electric cars, the battery is supplied by special lithium-ion battery packages, which has the phenomenon of power lithium battery recovery three types: the first class is the whole Car company; second type is battery production company; third category is the power lithium battery scrap recovery processing company and raw material company.
According to the regulations, the automotive company should bear the responsibility of the recovery, but the car companies are not universal. To a certain extent, the car enterprise is more like an electric car's "assembly factory", which is responsible for the use of normal, production supply, secondary use and recycling of lithium-ion battery packs during the warranty period, but is the specialty of battery companies. Unfortunately, battery companies are often excluded from the recycling system, and the responsibility is still unclear.
Third, lithium-ion battery pack recycling technology bottleneck is tolerant due to complex ingredients, dynamic lithium battery recovery and re-use facing many restrictions and higher technical thresholds. The type, specifications, process, etc. of the retired battery have a small difference, and in series, it is set in parallel form, and there is a diversity of the model, the time and conditions of use, resulting in complex dismantling.
At the same time, there is no unified standard for the power lithium battery, and there is still difficult to use a wide range of concentrated use. From the recycled battery, even if the lithium ion battery pack, the positive electrode material is also a five-flowers, the mainstream is lithium cobaltate, lithium manganate, lithium nickel-cobalt-oxanate, lithium iron phosphate, etc. Using a solution of acid-base solution, then the metal oxide is extracted with a variety of chemical procedures.
However, the ingredients of these oxides are different, and the mixture is more difficult. IV. Policies and regulations are not enough for industry insiders that my country has established "Dangerous Waste Polishing Prevention and Control Technology Policy", "Waste Battery Pollution Prevention and Control Technology Policy", 2016 National Development and Reform Commission led "new energy vehicle power battery recycling Technical Policy ".
All of these policies and technical standards are guided or recommended guidance documents, and the backbone companies on business regulations have reference guidance purposes, but there is no constraint for criminals. V. Recycling Technical Treatment The entire process of lagging waste dynamic lithium-ion battery pack recycling treatment includes dozens of complex steps such as discharge, dismantling, crushing, sorting, intrinsic, elemental synthesis, involving physical, chemical, materials, engineering, etc.
Cross discipline, technical complex length. At present, there are many developed countries such as Germany, the United States, and Japan, including Germany, the United States, and Japan are actively supporting and promoting national key technological engineering research and development in the field. my country has a little lag in a relatively international peer in terms of power lithium battery recovery technology technology.
For the above problems, the entire battery market should further explore how to safely and efficiently realize the ladder utilization of lithium-ion battery packs, establish a good recycling system that can be monitored, explores the ladder utilization technology of the power lithium battery, and realize the recycling of lithium-ion battery packs as soon as possible. Utilization, prevent unnecessary environmental pollution. .
