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.
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).
The synthesized powder was stored in a drying oven at 70 °C. The negative electrode composite was prepared by quantitatively mixing NTWO, LPSCl, and vapor-grown carbon fibers (VGCF) (Sigma-Aldrich, pyrolytically stripped, platelets (conical), >98% carbon basis, D × L 100 nm × 20−200 μm) in a weight ratio of 6:3:1.
Lithium (Li) metal shows promise as a negative electrode for high-energy-density batteries, but challenges like dendritic Li deposits and low Coulombic efficiency hinder its widespread large-scale adoption.
Yu et al. performed grinding modification of the mixed electrode material, which exposed more native section of the electrode material, strengthened the disparity in hydrophilicity, and recovered 94.38% purity of lithium cobaltate by flotation reach.
