The cover photo describing the crystal structure of Na5YSi4O12 with glass-ceramic Na+ superionic conductors. As discussed by Toshinori Okura, these glass-ceramic conductors have great potential and are one of the most important groups of solid electrolytes, not only because of its practical usefulness for advanced batteries but also for its three-dimensional ionic conducting nature.

Thermal energy storage (TES) by water vapor adsorption process has attracted increasing interest for its thermal applications such as space heating and cooling. However, the experimental energy density of the adsorbents may vary as the operating system and conditions change, which could be much lower than the theoretical energy density. In this manuscript, an experimental system has been designed and built to examine the effects of the regeneration temperature and relative humidity (RH) on a commercial silica gel material’s performance as adsorption TES material. The experimental energy density under different operating conditions were calculated. Up to 25 adsorption-desorption cycles were performed to examine the stability of the material and the repeatability of the results.
