Abstract: Meta-Capacitors In article number 2501848, Kai Sun, Yuan Yuan, Chaoyun Song, Runhua Fan, and co-workers pioneer a laminated meta-capacitor architecture comprising an epsilon-negative AgNWs/BaTiO3/PVDF intermediate layer sandwiched between two epsilon-positive BaTiO3/PVDF outer layers. The designed structure exploits plasma oscillation-induced negative permittivity to achieve a dramatically enhanced dielectric constant and significantly improved energy storage density, while maintaining low dielectric loss, offering a promising design for next-generation high-performance capacitors.
