Topic: Energy Materials for Emerging Electronic Devices under Extreme Conditions

Emerging electronic devices for modern energy systems are increasingly required to maintain high performance and long-term reliability under extreme or fluctuating environmental conditions. These conditions include wide temperature variations, high humidity, chemical corrosion, mechanical stress such as bending or stretching, and prolonged electrical or operational fatigue. Under such circumstances, the stability and reliability of energy materials play a decisive role in ensuring sustained device functionality.

This Special Issue focuses on recent progress in energy materials for emerging electronic devices operating under extreme conditions, with particular emphasis on materials engineering, interface design, and device optimization aimed at ensuring durability and operational stability. Promising approaches—such as composition tuning, defect management, interfacial passivation, barrier layer engineering, and robust encapsulation—have opened new pathways to mitigate degradation and improve long-term device stability.

Furthermore, reliability testing methodologies, including thermal aging, bias stress testing, environmental cycling, and mechanical fatigue evaluation, provide critical insights into degradation pathways and performance retention under realistic operating conditions.

The goal of this issue is to gather cutting-edge research that advances the understanding of environmental stability in energy materials and enables the practical deployment of electronic devices in applications such as batteries, solar cells, solar hydrogen production systems, and other advanced energy technologies. Contributions that bridge fundamental material mechanisms with real-world reliability requirements are particularly encouraged.
