Batteries and Supercapacitors

batteriesLithium-ion or otherwise, batteries keep lots of things going, and enable a mobile lifestyle: from mobile phones to intercontinental air travel. Batteries are complex devices whose overall performance and usefulness depend on many factors such as energy density, efficiency, durability, and sustainability. Research in this area is by nature interdisciplinary and involves chemists, physicists, materials scientists, and engineers.

Hollow Carbon Nanopolyhedra for Enhanced Electrocatalysis via Confined Hierarchical Porosity

Hollow Carbon Nanopolyhedra for Enhanced Electrocatalysis via Confined Hierarchical Porosity

A novel strategy for synthesizing hollow Co, N-codoped carbon nanopolyhedra from metal–organic frameworks using in situ evaporation of ZnO templates is proposed. The hollow carbon catalyst shows noticeable improvements in electrokinetics, oxygen reduction reaction selectivity/stability, and resistance to CH3OH, and the corresponding Zn–air battery exhibits a record open circuit potential, thanks to strong confinement effect.

Objectively Evaluating the Cathode Performance of Lithium-Oxygen Batteries

Objectively Evaluating the Cathode Performance of Lithium‐Oxygen Batteries

The cathode performance evaluation in lithium-oxygen batteries is much more complicated than that in lithium-ion batteries because of the complexity of the multi-phase electrochemical reaction. Conventional half-cell testing methods may give misleading conclusions. Modified half-cell testing methods are needed to get more instructive results for understanding the cathode chemistry and building high specific energy prototype cells.

Origin of Capacity Increasing in a Long‐Life Ternary Sn–Fe3O4@Graphite Anode for Li‐Ion Batteries

The origin of the capacity increasing is verified by a long-life Sn–Fe3O4@graphite composite anode, demonstrating that the capacity increasing comes from the partial reversible formation and dissolution of growing solid electrolyte interphase on the surface of active materials. This process causes the Li+ irreversible consuming, but also favors the kinetics of the ternary composite anode in the battery system.

Hydrogen-Treated Rutile TiO2 Shell in Graphite-Core Structure as a Negative Electrode for High-Performance Vanadium Redox Flow Batteries

Hydrogen‐Treated Rutile TiO2 Shell in Graphite‐Core Structure as a Negative Electrode for High‐Performance Vanadium Redox Flow Batteries

Hydrogen-treated TiO2-covered electrodes: A rutile shell is built around a graphite felt electrode to increase its selectivity for the V3+/V2+ redox reaction and to inhibit the hydrogen evolution reaction. The shell is partially reduced in hydrogen, forming oxygen vacancies in the TiO2 structure, which enhances the catalytic activity for the vanadium negative reaction. This results in an electrode that is suitable for vanadium redox flow batteries at high rates (up to 300 mA cm−2) and for long-term cycling.
