Recovery characteristics of lithium iron phosphate battery

Rapid growth and large scrap volume
Since the development of the electric vehicle industry, China has been the world's largest consumer market for lithium iron phosphate. Especially from 2012 to 2013, it grew at a rate of nearly 200%. In 2013, the sales of lithium iron phosphate in China were about 5797t, accounting for over 50% of global sales. 
In 2014, 75% of lithium iron phosphate cathode materials were sold to China. The theoretical life of lithium iron phosphate battery is 7 to 8 years (calculated by 7 years). It is estimated that about 9400 tons of lithium iron phosphate will be scrapped by 2021. If such a huge amount of waste is not treated, it will not only bring environmental pollution, but also energy waste and economic losses. 
Significant harm
Chemical substances such as LiPF6, organic carbonate and copper contained in lithium iron phosphate battery are included in the national hazardous waste list. LiPF6 has strong corrosiveness and is prone to decompose into HF when exposed to water; Organic solvents and their decomposition and hydrolysis products can cause serious pollution to the atmosphere, water, and soil, and pose a threat to ecosystems; Heavy metals such as copper accumulate in the environment and ultimately harm humans through the biological chain; Once phosphorus enters lakes and other water bodies, it is highly likely to cause eutrophication. It can be seen that if the waste lithium iron phosphate battery is not recycled, it will do great harm to the environment and human health.
