Reliable and Reusable All‐Solid‐State Contact‐Type Pre‐Lithiation Platform for High‐Performance All‐Solid‐State Batteries

Advanced Materials, EarlyView.
A reusable contact‐type pre‐lithiation platform enables uniform, precisely controllable pre‐lithiation at low stack pressure, suppressing interfacial degradation and thereby markedly improving initial Coulombic efficiency and cycling performance in all‐solid‐state batteries.

Photocatalytic Water Splitting on the Lunar Surface: Prospects for In Situ Resource Utilization

Advanced Materials Interfaces, EarlyView.
Water has been found in craters on the moon nearby locations which are illuminated >80% of the time. Photocatalysis uses energy from sunlight to drive chemical reactions such as water splitting to produce oxygen and hydrogen. It is a scalable technology that requires lighter equipment and utilizes resources available on the moon. ABSTRACT The discovery
