TL;DR: A remarkable electrode performance results from the facile charge transfer and Zn insertion in the structurally robust spinel featuring small particle size and abundant cation vacancies, as evidenced by combined electrochemical measurements, XRD, Raman, synchrotron X-ray absorption spectroscopy, FTIR, and NMR analysis.

TL;DR: The physicochemical characteristics of spinels such as their compositions, structures, morphologies, defects, and substrates have been rationally regulated through various approaches and can yield spinels with improved ORR/OER catalytic activities, which can further accelerate the speed, prolong the life, and narrow the polarization of fuel cells, metal-air batteries, and water splitting devices.

TL;DR: In this paper, the authors provide an overview of the development and characteristics of SSEs, followed by analysis of ion transport in the bulk and at interfaces based on different single-valent (Li+, Na+, K+) and multivalent (Mg2+, Zn2+, Ca2+, Al3+) cation carriers of contemporary interest.

TL;DR: Graphene, with a low lattice mismatch for Zn, is shown to be effective in driving deposition of Zn with a locked crystallographic orientation relation, and the resultant epitaxial Zn anodes achieve exceptional reversibility over thousands of cycles at moderate and high rates.

TL;DR: Batteries using quinone cathodes and metal anodes in aqueous electrolyte are reliable approaches for mass energy storage and an electrostatic potential computing method is developed to demonstrate that carbonyl groups are active centers of electrochemistry.
