On February 1, Volkswagen Group Parts Company is officially enabled in Salzgite's first automobile power lithium-ion battery recycling pilot factory. With the development of the project, the Volkswagen Group has taken a solid step in achieving the sustainable development process of the full-value chain end of the dynamic lithium-ion battery. This news, let the new energy car's power lithium-ion battery recovery problem again triggered.

"Battery is the core components of electric vehicles. As early promotion applications gradually enter the scrap period, the number of retired batteries begins to show scale trends. "The chief engineer of my country's Automobile Industry Association, Vice Secretary General Ye Shengji said in an interview with economic daily reporters that the power storage battery recycling industry has begun to transform from the previous demonstration.

Sitting on the new energy car retired battery market, the power storage battery recycling, the new life, quickly stood up. However, facing the seemingly attractive "cake", to taste the real "delicious" is not easy. Large and small - expected the actual recovery of the scrap volume under the promotion of policies and markets, in recent years, my country's new energy automotive industry has developed rapidly, and as early new energy vehicles gradually enter the scrap period, a batch of batteries walk into Retired procedure.

Relevant professionals introduce, lithium iron phosphate and ternary batteries are two battery types that are important for electric vehicles. Normally, when the residual capacity of the new energy vehicle power lithium ion battery is reduced to 70% to 80% of the initial capacity, the vehicle usage requirements cannot be satisfied. Conservative consideration, set the multiplier battery retirement period to 7 years, commercial vehicle battery retirement period is set to 5 years, predicted that my country's new energy vehicle retired battery is about 11.

6GWH, to 2025, new energy car retired battery quantity About 52.8GWH. According to the dynamic lithium-ion battery application branch prediction, considering the rise in the future decommissioning battery index, by 2030, the scale of the power lithium-ion battery will exceed 100 billion yuan.

But in fact, in the past year, the number of batteries entering the recycling company is much less than expected. Where is the battery? This is the primary issue that is currently troubled by battery recycling companies. The number of recycling outlets of "Official Xuan" has been more than two years.

In 2018, the Ministry of Industry and Information Technology, the Ministry of Science and Technology jointly issued a document, and clarifying the company to undertake the main responsibility of the powerful lithium-ion battery recycling. Then, a batch of batch of car companies or ladder use the company's designated recycling outlets like the spring bamboo shoots. However, according to the insiders feedback, there is more in the form of nearly 10,000 recovery points throughout the country.

Due to the low amount of retired battery, the use of the recovery channel is not perfect, most of the recycling network utilization is still low. The battery that is currently retired from the new energy car is more in the main body of the market, and some companies have received the battery directly, earn a difference. "Overall, it has published policies important for administrative policies, lacking enforcement and punishment measures, limited to industrial development.

The establishment of a sound retired battery recycling channel is the cornerstone of the healthy development of the industry. "Ye Shengji suggests, strictly set recycling company access conditions, strengthen the source of dynamic lithium-ion battery, thoroughly rectifying small workshop companies to recycle chaos, standardized recycling channels. More and less - New Recycling Company Difficulties in front of the seductive market prospects, massage companies.

According to the sky-eye check data, there are currently 242 companies in the country, including "power lithium-ion battery recycling", add 85 new in 2020, accounting for one-third. "my country's dynamic lithium-ion battery is handled, there is no problem in technology. "Zhejiang Huayou Circular Technology Co.

, Ltd. (hereinafter referred to as" Huayou Circulation ") General Manager Bao Wei said that in 2017, there is still a fear of retired power lithium-ion batteries, but by the end of 2020, the production of domestic battery recycling companies Already far exceeding the retirement amount of the retired dynamic lithium-ion battery. Some of Huayou cycles, some relatively independent third-party recycling companies continue to grow, become an important participant in the field of dynamic lithium-ion battery recycling.

Such as Greenmei, Guanghua Technology, Tianqi Shares and other listed companies are actively layout, seize the track. The whole vehicle also entered the battery recycling area. The technical expert of the Akilay Battery Operation Department Zhouze Run told the reporter that it will invest in the battery asset company with the Ningde Times, Guotai Junan and other companies.

The goal of the future is not just to do recycling, but to do the full life cycle management of the battery, from the upstream of the supply chain, during the production, in the car service, to retirement, material recycling, will be involved. "The biggest pain in the industry is the preparation of large-scale battery elimination. "In Bowei, it has occurred in the first safety accident such as the explosion of the power lithium-ion battery recycling company.

It is not technical, but suddenly, the newly added drain has put forward new challenges to the company. In fact, if the retired battery does not perform reasonable use of disposal, except for electric shock, fire and other electric safety hazards, the internal contained metal and electrolyte materials including nickel, cobalt, and electrolyte materials, will also have severe pollution to the ecological environment. Ye Saici said that the industry should continue to rely on the use of the technical innovation of the backbone company, but because the company has not formed a good profit point, it has caused the company's research and development, insufficient power, slow technology, forming a vicious circle.

He suggested to give full play to the industrial chain advantageous resources of the industry institutions, unite the industrial chain of the company, the powerful lithium-ion battery, and the recycling company and other industrial chain advantages and innovation, cultivate the leading company, leading the development of the industry. Low and high - recycled profit margin Low-use value high-new energy vehicle development initial in the early stage of lithium iron phosphate ion batteries, so the species of battery recovery is also important in lithium iron phosphate ion batteries, which does not contain cobalt, nickel equivalence Higher metal materials, regenerative utilization is difficult to earn. Plus the current number of current recovery is limited, it is difficult to form a scale effect, resulting in a large amount of production idle, and the recycling company has a profitable difficulties.

"There are many things in the automotive industry in price, and the price of only retired batteries is gradually increased. "Bao Wei told reporters that the power lithium-ion battery recycling industry is in the primary stage. Due to the significant signs, many companies will enter this industry with high cost, leading to the price of the dynamic lithium-ion battery, and does not meet the market law.

"The price of the ladder battery has been related to the price of the new battery". According to low-profile preferences, the value of power lithium ion battery recovery is high. Ye Yaji said that electric vehicle retired batteries still have high availability capacity, and metal materials such as nickel, cobalt, manganese have high recovery value under resource scarcity.

Carry out the retired battery ladder and regenerative utilization on the release of the full life cycle value of the dynamic lithium ion battery and has positive significance. "Huayou cycles accumulated battery, from direct battery packs, close to 10,000 tons, if plus some of the recycled middleware, the total amount may exceed 30,000 tons. "Bao Wei said that the company has reduced production costs through large-scale operation, and has leading technology, combined with the recovery treatment of the waste material of the battery factory, and the resource regeneration sector has achieved profitability.

In addition to the exception of the profit, Zhouze Run analyzed that there are three difficulties in technology, "I can't get" "I can't see" "I can't get it". "I can't see" means that the lithium-ion battery is a data-driven business. It is difficult to have a company to see the full amount of data; "can't get" is property rights issue, the supervisory department requires the main plant to take responsibility, but the battery is in the user I can't get the battery; "It's not good" can't see the data, can't get the battery, the industry chain is not smooth, causing it difficult to land.

Before the scale effect is formed, diversified operation, technical upgrade, and hug heating into the mainstream mode of industry company exploration. At the same time, the development of the market environment, the establishment of traceability system and environmental awareness is still the focus of the industry, after all, the retired battery that has opened the scale trend is not available for the recycling industry.
