Lithium (Li) metal is widely recognized as a highly promising negative electrode material for next-generation high-energy-density rechargeable batteries due to its exceptional specific capacity (3860 mAh g −1), low electrochemical potential (−3.04 V vs. standard hydrogen electrode), and low density (0.534 g cm −3).
To reduce the risk in the crushing process of used lithium batteries, 10 used lithium batteries (weighing approximately 1 kg) were first immersed in a NaCl solution with a mass fraction of 20 % and fully discharged for 24 h.
Efficient separation of small-particle-size mixed electrode materials, which are crushed products obtained from the entire lithium iron phosphate battery, has always been challenging. Thus, a new method for recovering lithium iron phosphate battery electrode materials by heat treatment, ball milling, and foam flotation was proposed in this study.
This method offers a purified electrode material suitable for the subsequent hydrometallurgical recovery process, thereby presenting a novel approach to recovering waste lithium-ion batteries. Discover the latest articles, news and stories from top researchers in related subjects.
