Material regeneration technology for lithium batteries and the current status of industrial applications in China and Overseas

This presentation will give a comprehensive overview of the lithium battery market. There will be a summary of the research on battery recycling and regeneration technologies for both LFP and ternary lithium batteries.  as well as the development of an ultra-short separation system via a hydro-metallurgical process for high nickel EV batteries, a direct recycling method for various spent electrodes, carbon assessment system for battery whole life, and more.

For the ternary lithium battery hydrometallurgical process, after removing impurities, a novel extractant named BC196, independently developed by Botree Cycling, can co-extract Ni, Co, and Mn from solution in one step, and the stripping can be directly utilised to produce ternary precursor materials.

The LFP battery market is growing rapidly and is widely used for EV and energy storage. The ph regulated precipitation method developed by Botree Cycling is well-suited to black powder with high impurities and effectively recovers Li, Fe, and P.

Additionally, a short and efficient direct recycling process for spent electrodes has been developed by Botree Cycling. Non-destructive de-powdering solutions and essential equipment are suitable for the most widely used batteries, including LFP, NCM, and LMO, which can help reduce the use of complex chemical reagents during hydrometallurgical processes with high recovery rates, short process times, low cost, and reduce carbon emissions significantly. Efficient recycling and reproducing new battery materials can reduce its carbon footprint by at least 30%. Recycling also creates new carbon footprints, with 90% coming from the raw materials (acid and alkali) and energy (electricity and heat) used during battery manufacturing.
