Materials Horizons

Quasi-solid-state micro-supercapacitors with cellular graphene film as the active material and polyvinyl alcohol/H₃PO₄as the gel electrolyte have been fabricated. The 3D porous graphene films not only serve as high performance supercapacitor electrodes, but also provide an abundant ion reservoir for the gel electrolyte.

Nature-inspired ionic conductors based on supramolecular nanofibril are developed for flexible and stretchable strain/pressure sensors.

This review provides insights into the role of particle geometry in biomedical applications.

Strategies that could be used to develop non-precious-metal based catalysts towards the OER/ORR in alkaline electrolyte based zinc–air systems are briefly reviewed.

The concept of electronic dimensionality,i.e., the connectivity of the atomic orbitals that comprise the lower conduction band and upper valence band, is introduced to better account for the device performance of the perovskite-based solar cells.

The emergence of oxidized oxygen RIXS features at high voltages for Ni-rich layered oxide cathodes.

This review systematically summarizes the limitations of solid electrolytes including inorganic solid electrolytes, solid polymer electrolytes, and composite solid electrolytes.

A general strategy for the fabrication of mechanically robust ionogels by hydrogen bonding between elastomers and [NTf₂]-based ILs is demonstrated.

A new way to fabricate asymmetric, flexible, and ultrathin liquid metal Janus films with electrical, optical, and thermal anisotropies is demonstrated.
