TL;DR

This paper presents a method to enhance super-capacitor capacitance by transforming the separator into an active diode-like component, achieving significant increases without and with bias.

Contribution

It introduces a novel separator modification that actively boosts super-capacitor capacitance, a new approach in energy storage device design.

Findings

15% capacitance increase with passive diode-like separators

Additional 15% increase with biased separators

Separator modification effectively enhances super-capacitor performance

Abstract

We show how to increase the capacitance of super-capacitors by modifying the otherwise passive separator layer and turn it into an active diode-like structure. We demonstrate 15% capacitance increase for a diode-like separators without a bias. Additional 15% capacitance increase has been observed for biased separators.
