Flash Recycling of Graphite Anodes
Abstract
The ever‐increasing production of commercial lithium‐ion batteries (LIBs) will result in a staggering accumulation of waste when they reach their end of life. A closed‐loop solution, with effective recycling of spent LIBs, will lessen both the environmental impacts and economic cost of their use. Presently, mHCl. The flash‐recycled anode preserves the graphite structure and is coated with a solid‐electrolyte‐interphase‐derived carbon shell, contributing to high initial specific capacity, superior rate performance, and cycling stability, when compared to anode materials recycled using a high‐temperature‐calcination method. Life‐cycle‐analysis relative to current graphite production and recycling methods indicate that flash recycling can significantly reduce the total energy consumption and greenhouse gas emission while turning anode recycling into an economically advantageous process.
