Particle‐Size‐Dependent Lithium‐Ion Transport in PEO/LLZO Composite Electrolytes

Small Structures, Volume 7, Issue 6, June 2026.
A continuum modeling framework quantifies the critical polymer/ceramic interfacial resistance required for ceramic fillers to reduce polarization in PEO/LLZO composite electrolytes. The model shows that this threshold scales linearly with LLZO particle size, while remaining largely insensitive to ceramic loading.

A Control Strategy for Variable Speed Condenser Based on Doubly‐Fed Machine

IET Smart Energy Systems, Volume 2, Issue 2, Page 120-130, June 2026.
This paper proposes a variable speed condenser (VSC) control strategy based on a doubly fed machine. It can be installed in PV stations and wind farms to enhance the grid‐connection performance of renewable energy power plants. ABSTRACT The lack of active power support capability in power systems with large‐scale renewable energy integration has become
