Li-ion battery (LIB) recycling has become an urgent need with rapid prospering of the electric vehicle (EV) industry, which caused a shortage material resources and led to increasing amount retired batteries. However, global LIB effort is hampered by various factors such as insufficient logistics, regulation, technology readiness. Here, challenges associated their possible solutions are summarized. Different aspects recycling/upcycling techniques, worldwide government policies, economic...
Lithium-ion batteries (LIBs) are widely applied in portable electronics, electric vehicles (EVs), and grid storage systems. They need sustainable end-of-life battery management to reduce greenhouse emissions resource consumption create a low-carbon future. Here, we report an efficient upcycling method, converting spent polycrystalline LiNi0.33Co0.33Mn0.33O2 (NCM111) up single-crystal LiNi0.8Co0.1Mn0.1O2 (NCM811) with lean input of precursors. A systematic investigation the microstructure...
Abstract Despite significant progress in energy retention, lithium‐ion batteries (LIBs) face untenable reductions cycle life under extreme fast‐charging (XFC) conditions, which primarily originate from a variety of kinetic limitations between the graphite anode and electrolyte. Through quantitative Li + loss accounting comprehensive materials analyses, it is directly observed that operation LIB pouch cells at 4 C||C/3 (charging||discharging) results plating, disadvantageous...
Abstract Dry‐process fabrication using fibrillatable binder is emerging as a promising method to produce high‐loading electrodes for energy storage applications, favored by its cost‐efficiency and eco‐friendliness. While previous studies have demonstrated the advantages of dry process over traditional slurry method, there remains gap in understanding how particle size active materials influences mechanical electrochemical performance electrodes. In this study, four different NaCrO 2 (Average...
Abstract The rapid accumulation of end‐of‐life lithium‐ion batteries necessitates sustainable recycling pathways, particularly for the industry‐prominent nickel‐rich NCM (LiNi x Mn y Co z O 2 , x+y+z = 1, x>0.8) materials. Direct presents a promising solution but is hindered by susceptibility these materials to impurities, moisture, particle cracking, and thermal degradation, especially in hydrothermal relithiation methods. This study reveals that impurities lead severe surface...
Despite significant progress in recycling spent lithium-ion batteries (LIBs), nondestructive, direct methods still face untenable discrepancies multiple cathode chemistries, which primarily originate from a variety of structure stabilities during the process. Through systematic investigation microstructure evolution relithiation treatment, we observed inevitably induced defects and Li/Mn disordering LiNi0.5Mn1.5O4 cathode, contributing to sluggish Li+ transport irreversible capacity loss....
Lithium-ion batteries (LIBs) face untenable reductions in cycle life under extreme fast-charging (XFC) conditions, which primarily originate from a variety of kinetic limitations between the graphite anode and electrolyte. Through quantitative Li+ loss accounting comprehensive materials analyses, it is directly observed that operation LIB pouch cells at 4 C||C/3 (charging||discharging) results Li plating, disadvantageous solid-electrolyte-interphase formation, solvent co-intercalation...
