Partial Inhibition of Spontaneous Voltage Recovery (`Memory Effect') of Commercial EDLC Supercapacitors by Stationary Magnetic Field

TL;DR

This study investigates how a stationary magnetic field can partially inhibit the spontaneous voltage recovery, known as the memory effect, in commercial EDLC supercapacitors after full charge and discharge cycles.

Contribution

It presents preliminary evidence that a stationary magnetic field can reduce the memory effect in EDLC supercapacitors, a novel approach to controlling supercapacitor behavior.

Findings

Magnetic field partially inhibits voltage recovery in EDLCs.

The effect observed in supercapacitors with 1-25 Farad capacitance.

Potential for magnetic field application in supercapacitor management.

Abstract

We report preliminary findings on partial inhibition of spontaneous voltage recovery under open circuit conditions, following full charge and discharge to null potential (`memory effect'), of commercial EDLC supercapacitors of Faradaic values ranging between 1-25 Farad (rated at 2.7 volts), upon exposure to an approximately homogeneous, stationary magnetic field of about 100 milli-Tesla.
