Novel Electrode Materials for Rechargeable Batteries

This Special Issue of Molecules, “Novel Electrode Materials for Rechargeable Batteries”, features ten published papers that reflect the diversity and dynamism of current research in energy storage and conversion. Several studies focus on lithium- and sodium-ion batteries, investigating Ni-rich cathode materials, hard carbon anodes, F-doped layered transition metal oxides, and stable anode-free configurations. Other contributions explore magnesium–sulfur batteries and highlight recent advances in electrolyte design. Beyond batteries, research on photocatalysts, thermoelectric materials, and hydrogen production technologies provides complementary insights into sustainable energy solutions. Together, these contributions demonstrate significant progress in material design, electrochemical performance optimization, and catalytic strategies, offering crucial perspectives for the future of rechargeable batteries and green energy technologies.
