The Journal of The Electrochemical Society is publishing a focus issue in connection with the Heterogeneous Functional Materials for Energy Conversion and Storage 4 symposium held at the 249th ECS Meeting in Seattle, WA, from May 24–28, 2026.
Heterogeneous functional materials (HeteroFoaMs) are pervasive in electrochemical devices. These devices consist of multiple materials combined at multiple scales (from atomic to macro) that actively interact during their functional history in a manner that controls their collective performance as a system at the global level. The principal motivation for this focus issue is to provide a place to publish the science that controls emergent properties in heterogeneous functional materials as a foundation for design of functional material devices with performance not bound by constituent properties.
