Summary: Li-rich Mn-based cathode materials (LRM) have attracted extensive attention for their high energy density, but the irreversible oxygen precipitation and structural transformation during cycling process hinder their practical applications. In this study, a Co-free Li-rich Mn-based cathode material Li1.2Ni0.185Mn0.585Fe0.03O2 was synthesized with the formation of an AlPO4-Li3PO4 double shell in situ on its surface. The synergistic modification of the AlPO4-Li3PO4 dual shell significantly improves the cycling stability and rate performance.

Summary: This study proposes a method of plasma-modified TiN to improve the electrochemical performance and stabilize the cathode-electrolyte interface reaction of Ni-rich LiNi0.8Co0.1Mn0.1O2 (NCM811) cathode material. The physicochemical properties, Li storage performance, and factors for improving the electrochemical performance were systematically investigated. The NCM811-TiN/graphite pouch cell showed high reversible capacity and cycle stability without changing the bulk structure and morphology, facilitating the practical use of safe and high-energy-density Li-ion batteries.

Summary: The research demonstrates that by precisely controlling the coating concentration and temperature, Nb2O5 can effectively bond to the surface of LiMn2O4 spinel cathode material, significantly improving the electrochemical performance. However, at high coating concentrations, Nb5+ ions diffuse into the cathode structure, leading to a decrease in cycling performance.

Summary: Aqueous zinc batteries (ZIBs) have gained attention for their safety and eco-friendliness. Adding Mn2+ salts to ZnSO4 electrolytes has been shown to enhance the energy densities and cycling life of Zn/MnO2 batteries. A new study investigates the role of Mn2+ electrolyte additives by using a ZIB with a Co3O4 cathode instead of MnO2, revealing similar electrochemical characteristics. The study provides insights into the reaction mechanism and pathway, highlighting the reversible Mn2+/MnO2 deposition/dissolution process and the involvement of Zn2+/Zn4SO4(OH)(6)•5H2O deposition/dissolution during part of the charge/discharge cycle.
