The backwardness of resource development and utilization, the low level of power battery technology, and the blank of battery recycling and reuse system have limited industrial competitiveness. China must get rid of existing bottlenecks, speed up the construction of standardized systems, improve the recycling and reuse system, and master breakthrough core technologies in order to gain an advantage in this competition.
The battery contains a variety of harmful substances, and random disposal will have a huge impact on the ecology. Lithium batteries need to be recycled after the end of their life cycle, mainly for environmental and economic considerations. According to the 2011 US Hazardous Substances List data, Ni, Co, and phosphide scores exceeding 1,000 are considered high-risk substances. The electrolyte of the waste lithium ion battery and its conversion products, such as LiPF6, LiAsF6, LiCF3SO3, HF, P2O5, etc., the solvent and its decomposition and hydrolysis products, such as DME, methanol, formic acid, etc., are toxic and harmful substances, which can cause personal injury. even death.
Battery material recycling has multiple economic values, including energy value re-excavation and material regeneration value. The economic aspect is also worthy of attention. It mainly includes three aspects: 1 After the lithium battery is retired on high-end electrical appliances, it can still meet the demand of some low-end electrical appliances, usually electric toys, energy storage facilities, etc. The use can give lithium batteries more value; 2 even if the electrical performance can not meet the deeper use, but the relatively rare metals such as Li, Co, Cu, etc. still have the regeneration value; 3 due to the partial metal reduction energy consumption and metal There are huge differences in regenerative energy, such as Al, Ni, and Fe, which cause metal recovery to have economic value in energy consumption.

China’s new energy automobile industry has developed rapidly. At the national level, as early as 2009, various incentive policies were introduced to promote the healthy development of the industry, and the future policy will gradually transition to mandatory. In recent years, the sales growth rate has remained at a high level. From 2013 to 2017, the national sales growth rate has exceeded 100%. It is estimated that 2020 will realize the sales of 2 million new energy vehicles nationwide, and the corresponding battery is expected to reach 80Gwh or above.
Since the power battery has maintained a high growth rate since 2013, and then began to enter the medium and high growth rate in 2018, the timeline for scrapping will lag five years. From 2018 to 2021, it will show a high growth rate, when the base is raised to a certain level. To the extent, the market began to grow steadily. Chuan Cai Securities expects that the lithium battery scrap will be around 30Gwh this year, and the number will increase to about 150Gwh by 2025.
Power lithium batteries have entered a period of high growth of centralized decommissioning. In addition, recycling policies have been introduced one after another, and corresponding laws and regulations have been gradually improved. Companies in the industry are expected to achieve steady growth in profits.
