Do nanostructured storage devices increase capacitance density?

Nanostructured storage devices with 3D metal–insulator–metal (MIM) architectures—which require conformal metal and insulator deposition inside porous nanostructures—have successfully increased capacitance density, and therefore energy storage, per unit planar area (Fig. 3b, Supplementary Table 3).

Do thin film microcapacitors have record-high electrostatic energy storage density?

Here we report record-high electrostatic energy storage density (ESD) and power density, to our knowledge, in HfO 2 –ZrO 2 -based thin film microcapacitors integrated into silicon, through a three-pronged approach.

Are energy storage devices unipolar?

Furthermore, because energy storage devices are unipolar devices, for practical application, we must consider the non-switching I–V transients, as there will be no voltage of the opposite polarity to switch any ferroelectric polarization that may be present.

Are electrostatic microcapacitors the future of electrochemical energy storage?

Moreover, state-of-the-art miniaturized electrochemical energy storage systems—microsupercapacitors and microbatteries—currently face safety, packaging, materials and microfabrication challenges preventing on-chip technological readiness2,3,6, leaving an opportunity for electrostatic microcapacitors.

Does -E BD limit energy storage in dielectric capacitors?

This approach can overcome the conventional κ -E BD trend which limits energy storage in dielectric capacitors (Supplementary Text), ultimately leading to the largest volumetric ESD value reported for a BEOL-compatible dielectric (Supplementary Table 1).
