  Giant energy storage and power density negative capacitance superlattices

  Using a three-pronged approach — spanning field-driven negative capacitance stabilization to increase intrinsic energy storage, antiferroelectric superlattice engineering to increase total energy storage, and conformal three-dimensional deposition to increase areal energy storage density — very high electrostatic energy storage density and power density are reported in HfO₂–ZrO₂-based thin film microcapacitors integrated into silicon.

  Ultralow-resistance electrochemical capacitor for integrable line filtering

  A miniaturized narrow-channel in-plane electrochemical capacitor shows drastically reduced ionic resistances within both the electrode material and the electrolyte and an ultrahigh areal capacitance by downscaling the channel width with femtosecond-laser scribing.

  Thickness-independent capacitance of vertically aligned liquid-crystalline MXenes

  Electrode films prepared from a liquid-crystal phase of vertically aligned two-dimensional titanium carbide show electrochemical energy storage that is nearly independent of film thickness.
