背景技术Background technique
锂离子电池广泛应用于储能、电动汽车、便携式电子设备等等多个领域。储能系统以及电动汽车被认为具有减少化石能源消耗、提高再生能源利用率的巨大潜力，因而近年来得到了国家的大力扶持。此外，随着生活水平的提高，手机、笔记本电脑等移动电子设备的需求量逐渐增加，使得对锂离子电池的需求不断增长。然而，锂离子电池使用寿命一般在8年以下，因而近年报废锂离子电池的数量急剧增加。我国是锂资源短缺的国家，从废旧锂锂离子电池中回收锂具有战略价值。然而由于磷酸铁锂电池的锂含量低，目前的火法冶金技术无法从磷酸铁锂电池回收锂资源。湿法冶金技术对锂有较高的回收率，然而湿法冶金技术常需要大量的酸、碱，产生大量的废水，环境负担较大。Lithium-ion batteries are widely used in energy storage, electric vehicles, portable electronic devices and many other fields. Energy storage systems and electric vehicles are considered to have great potential to reduce fossil energy consumption and improve the utilization rate of renewable energy, so they have been vigorously supported by the state in recent years. In addition, with the improvement of living standards, the demand for mobile electronic devices such as mobile phones and notebook computers has gradually increased, resulting in an increasing demand for lithium-ion batteries. However, the service life of lithium-ion batteries is generally less than 8 years, so the number of discarded lithium-ion batteries has increased sharply in recent years. my country is a country with a shortage of lithium resources, and it is of strategic value to recover lithium from waste lithium-ion batteries. However, due to the low lithium content of lithium iron phosphate batteries, the current pyrometallurgical technology cannot recover lithium resources from lithium iron phosphate batteries. Hydrometallurgical technology has a high recovery rate of lithium, but hydrometallurgy technology often requires a large amount of acid and alkali, produces a large amount of wastewater, and has a large environmental burden.
