Summary: Biomass-derived porous carbon/MoO2@TiO2 (LC/MoO2@TiO2) anode materials were prepared via hydrothermal route for lithium-ion batteries (LIBs). Transmission electron microscopy and energy dispersive X-ray spectroscopy of LC/MoO2@TiO2 showed that MoO2 and TiO2 nanoparticles were uniformly embedded in the porous and surface of honeycomb porous carbon (LC). The LC/MoO2@TiO2 anode exhibits excellent rate capability and maintains a stable specific capacity of-600 mAhg-1 at a current density of 100 mAg-1 after 100 cycles. Moreover, at a current density of 500 mAg-1 its reversible capacity can reach 310 mAhg-1 after 250 cycles. Therefore, the structure of MoO2 and TiO2 nanoparticles anchored of a porous LC can not only buffer the volume change during lithiation /delithiation process but also provide more active surface area, and more convenient and efficient channel for lithium-ion transport and storage.

Summary: The addition of acrylonitrile (AN) in carbonate-based electrolytes has been reported as an effective method to achieve uniform and dense lithium (Li) deposition and improve the coulombic efficiency of Li metal anodes. The electrochemical, spectroscopic, and theoretical studies show that AN is cathodically electropolymerized on the Li surface, forming a polyacrylonitrile artificial solid electrolyte interface that allows for uniform nucleation and growth of Li deposition with reduced side reactions. The effectiveness of AN additive is demonstrated in Li pouch cells with excellent cycle stability under realistic charge-discharge conditions.

Summary: Lithium-sulfur (Li-S) batteries are highly promising high-energy-density secondary batteries due to their ultrahigh energy density and low cost. A dual-functional electrolyte additive, lithium selenide (Li2Se), is proposed to address the challenges faced by Li-SPAN batteries, including sluggish sulfur kinetics and uncontrollable Li deposition. Li2Se improves kinetics by attacking polysulfides and forms a stable selenide-containing organic-inorganic hybrid solid electrolyte interphase (SEI) to enhance Li deposition. The Li2Se-assisted Li-SPAN battery exhibits high discharge capacities, enhanced rate performance, and outstanding cycling stability.

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.
