Summary: By using a simple self-assembly strategy, nanoarchitectures were synthesized as anode materials for sodium-ion batteries, showing high capacity and cycle stability. The nanofiber electrode exhibited a high specific capacity of 271 mAh g-1 at a current density of 50 mA g-1, maintaining a capacity retention of 97% after 200 cycles. Furthermore, it retained 85% capacity after 1000 charge-discharge cycles at a high current density of 1 A g-1. The nanofiber structure enhanced electrochemical properties and the carboxylic group decreased solubility in the organic electrolyte, making it a potential material for sustainable and stable organic anodes in sodium-ion batteries.

Summary: This study performed operando dual-edge X-ray absorption spectroscopy on both transition-metal ordered and disordered Li-Ni0.5Mn1.5O4 materials during the electrochemical delithiation and lithiation process. The analysis of a large dataset using a chemometric approach provided reliable insights into the redox activity and local structural changes of Ni and Mn. The results confirm the dominant redox activity of the Ni2+/4+ redox couple involving a transient Ni3+ phase, and also highlight a reversible minority contribution of Mn3+/4+ in both LNMO materials. While the reaction steps and involved reactants are generally similar in ordered and disordered LNMO materials, differences in reaction dynamics and local structural evolution induced by TM ordering are emphasized.

Summary: Microwave calcination is proposed as an alternative route to prepare layered P2-Na2/ 3Ni1/3Mn2/3O2 for sodium-ion batteries. The sample obtained under the fastest conditions of a heating ramp of 20 degrees C min-1 for 2 hours showed well-crystallized rounded particles. It exhibited low internal cell resistance and high diffusion coefficients, allowing for the highest capacity at 1 C and maintaining discharge capacity for at least two hundred cycles.

Summary: Microwave calcination is introduced as a substitute for conventional heating in electric furnace for the production of high-performance electrodes for sodium-ion batteries. The microwave annealing process allows for shorter annealing time and the preparation of pure and highly crystalline Mg-doped Na2/3Ni1/3Mn2/3O2 samples. The electrochemical performance of the microwave calcined samples is superior to a reference sample prepared by conventional heating methods, as evidenced by the kinetic response at different stages of galvanostatic cycling. This improvement can be attributed to the larger crystallite size and lower microstrains achieved through microwave annealing, which result in reduced resistive behavior, higher Na+ diffusion coefficient, and lower internal resistance of the positive electrode.

Summary: The magnesium driven reaction in the olivine-type MgMn0.5Zn0.5SiO4 structure is investigated through experimental tests and density functional theory (DFT) calculations. Partial replacement of Mn in Oh sites by Zn in the MgMn0.5Zn0.5SiO4 cathode is successfully achieved using a simple sol-gel method. Comparison with the well-known MgMnSiO4 olivine-type structure provides insights into the structure and magnesium extraction/insertion properties of the novel olivine-type (Mg)(M1)(Mn0.5Zn0.5)(M2)SiO4 composition. DFT calculations further extend the study to other divalent elements in the olivine-type (Mg)(M1)(Mn0.5M0.5)(M2)SiO4 structure with M = Fe, Ca, Mg, and Ni. The results suggest that the energy density can be tuned between 520 and 440 W h kg(-1) based on the atomic weight and redox chemistry properties, offering new possibilities for cathode material development in Mg batteries.

Summary: After a delay of more than 30 years, sodium analogs are now entering the market as an alternative to lithium-ion batteries. These sodium-ion batteries address concerns about sustainability, production costs, safety, and toxicity. The electrode materials of these batteries can contain sodium, iron, or manganese, eliminating the need for cobalt cathode compounds and copper anode current collectors. Manganese, with its multiple oxidation states and abundance, is favored as a component in these batteries. However, further research is needed to explore the role of manganese in different structural families.
