The lithium-ion battery is a device that is chemically and electrical energy-mutually converted, and the internal opposing chemical reaction occurs inside, and the side reaction between the negative electrode and the electrolyte is a tight limiting factor of its cycle life. Usually consumer batteries have a life cycle of 3-6 years, according to the function and replacement frequency of the appliance, its scrap cycle is around 5 years. Since new energy vehicles strongly promote it from 2013, it is possible to calculate the pilot of the battery update will be around 2018.

The market is generally expected that in 2018 will usher in a dynamic lithium-ion battery scrap peak. 2018 - 2020, the national accumulated scrapped dynamic lithium-ion battery volume will reach 120,000 to 200,000 tons. There is a more radical point of view, by 2020, the amount of scrap will reach 280,000 -3 million tons.

According to the reporter, there is currently two kinds of solutions for the retired dynamic lithium-ion battery. Today's solution is divided into two types: ladder utilization and dismantling recycling. The so-called ladder is used, refers to the battery used by high-power.

After inspection, the principle is similar to that of a battery advertisement: the battery used by the toy car, the remote control can be used, the current ladder It is only aimed on a low-power electrical equipment to achieve secondary utilization. After the ladder is used, the battery will reach the degree of retreat, will enter the dismantling recovery link. The dismantling recovery is a resolution, separation, purification, smelting of the scrapped battery to solve the chemical method, and recover the metal elements such as lithium, nickel, cobalt, manganese in the battery.

The industry told reporters that the current power lithium-ion battery solves mostly to disassemble the electrical cell, and there is no further solving, and the tradder is always the end. From this solution, the chemical solution cost is the question of the primary consideration, followed by the evaluation of battery loss, utilization, etc. during the ladder utilization process, reasonable differential utilization and cost of the process.

From this point of view, in the technical still is not mature, the industry has not yet formed a scale, it may be that it may be laborious. Dangerous or opportunities? At present, there are very few companies with the qualification of the dismantling power lithium-ion battery. The development of used batteries and the development of special technical equipment will still have a lot of funds.

However, there is no fixed recycling channel for the raw materials disassembled from the battery. The recovery price of raw materials has always been fluctuated, causing the current battery solution company to achieve a profitable state. The stage of industrialization will eventually arrive.

Suppose the new energy passenger car battery usage period 5 years, commercial vehicles 4 years, after the expiration of the update rate (that is, the total amount of battery that is refundable, the total amount of battery should be retired) has increased year by year, and the power lithium-ion battery is based on the in recent years. Yield can be measured in 2018, and the powerful lithium-ion battery added a wastewashing machine or 11.14GWh, which has increased significantly by 278.

9%. In recent years, the sales of electric vehicles have climbed year by year, which means that the amount of scrap will rise, and the market space will be very attractive. According to relevant data, it is estimated that by 2020, my country's total amount of waste lithium-ion battery will reach 200,000 tons.

Industry prediction data shows that in 2018, the waste power lithium-ion battery recovery market can reach 5 billion yuan, 2020 to 2023, the scale of waste-powered lithium-ion battery recovery will further rise to 136-31 billion yuan. Recently, the Ministry of Industry and Information Technology announced that the list of companies in accordance with the standardization of new energy vehicles, the company's standard conditions, the Ministry of Industry and Information Technology in accordance with the "Interim Method of Recycling Management", " After the company's declaration, provincial industry and information management authorities reviewed, expert review, on-site verification and online publicity, etc. will meet the "New Energy Automobile Waste Battery Comprehensive Utilization Industry Standard Condition" Company List (Batch).
