Polymer dielectric composites are promising candidates for next-generation pulse capacitors, yet it remains challenging to combine high energy density, high charge-discharge efficiency, and reliable operation at elevated temperatures. Here, 1D core-shell SiO2@Hf0.5Zr0.5O2 (SiO2@HZO) nanofibers are designed as dielectri...

Polymer dielectrics operating under extreme environments require increasingly higher demands on electrical insulation performance. Polyimide (PI), one of the most promising candidates for high‐temperature energy‐storage dielectrics, tends to form charge‐transfer complexes (CTCs) under high temperatures and high ele...

Dielectric polymers for high‐temperature capacitive energy storage require both high thermal stability and electrical insulation. Although the rigid conjugated structure of polyimide affords a high glass transition temperature, making it a promising candidate, it also introduces compromised electrical insulation th...
