An environmentally friendly leaching process for recycling valuable metals from spent lithium-ion batteries is developed. A sol–gel method utilized to resynthesize LiNi1/3Co1/3Mn1/3O2 the leachate. Lactic acid chosen as a and chelating agent. The efficiency investigated by determining contents of metal elements such Li, Ni, Co, Mn in leachate using inductively coupled plasma optical emission spectroscopy. cathode materials pretreatment regenerated freshly synthesized are examined X-ray...
Rapid development of energy storage system causes a burst demand lithium-ion batteries (LIBs), and large number spent LIBs with high valuable metals are produced. Here we propose novel application oxalic acid leaching to regenerate Li(Ni1/3Co1/3Mn1/3)O2 (NCM) cathodes from LIBs. With lithium dissolving into the solution, transition transform oxalate precipitates deposit on surface NCM cathodes, separating in one simple step. After mixing certain amount Li2CO3, together unreacted directly...
Abstract Although the flexibility of quasi−solid polymer electrolyte favors its surface conformal to electrode, interfacial damage originating from side reactions between and electrode remains dominant for battery failure. The design electrolytes compatible with both aggressive nickel−rich cathode lithium metal anode persists critical application high−voltage batteries (LMBs). Herein, a chemical/electrochemical response strategy is proposed construct simultaneously stable cathodic anodic...
Abstract LiFePO 4 is extensively used as a cathode material in lithium‐ion batteries because of its high safety profile, affordability, and extended cycle life. Nevertheless, inherently low transport kinetics restricted electronic conductivity considerably limit rate performance. Furthermore, the failure mechanisms specific to various cycling rates are not well examined. This study presents functional interface layer designed regulate rate‐dependent behavior . At elevated charge/discharge...
Constructing composite solid electrolytes (CSEs) integrating the merits of inorganic and organic components is a promising approach to developing high-performance all-solid-state lithium metal batteries (ASSLMBs). CSEs are now capable achieving homogeneous fast Li-ion flux, but how escape trade-off between mechanical modulus adhesion still challenge. Herein, strategy address this issue proposed, that is, intercalating highly conductive, homogeneous, viscous-fluid ionic conductors into robust...
The high-viscosity issue of ionic liquids hinders the practical use liquid electrolytes for high-energy density batteries. Here, we demonstrate a novel heteroatom Si substituent imidazolium-based electrolyte, which has low viscosity and high conductivity, weakens activity C-2 position imidazolium cation, prevents formation highly loose lithium corrosion layer, enables Li/LiFePO4 cycling with coulombic efficiency (up to 99.7%) greatly enhanced stability. electrolyte is intrinsically safe...
