Abstract

Abstract

As a key raw material supporting the development of strategic emerging industries, lithium metal is also an important new energy metal in this century. In this paper, the technology and process flowsheet of lithium metal recovery and reuse from terminal waste products in the world were studied. The optimal recovery rate was obtained under different technical conditions. From 2000 to 2019, the in-use stock of lithium metal in lithium ion batteries increased rapidly, from 30 tons to 18 000 tons, and will increase to 430 000 tons in 2035; Under the existing recycling technology, only lithium metal in alloy and lithium ion battery used can be recycled, and the recycling technology is mainly focused on lithium ion battery. Based on this, the material flow analysis method was further used to evaluate the potential of lithium metal recovery and reuse in Mainland China from 2020 to 2035. The results show that: (1) Lithium ion batteries are the main source of recovered lithium; (2) By 2035, the in-use stock of lithium metal will increase to 430 000 tons, and the recovery potential of lithium metal will increase year by year and exceed 40 000 tons by 2035;(3) The recovery potential of lithium in alloy is small and difficult. Finally, relevant suggestions are put forward in the conclusion to provide support for effective supply of lithium metal resources.
