Lithium-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.

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.

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.

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.

Nitrogen-doped carbon nanospheres are synthesized from two cheap, readily available and sustainable precursors: tannic acid and urea. In combination with a structuring agent, the nitrogen content, sphere size and surface can be tuned. The straightforward oven synthesis offers a more sustainable synthesis alternative to classical conductive soots.
