The Major Differences Between Supercapacitors and Batteries

White Paper Overview

Supercapacitors and batteries are storage technologies which have strengths for different applications. Supercapacitors are ideal where power bursts are required, long life backup power or a high number of charge/discharge cycles. The two technologies can complement each other in systems that require a combination of these as well as long discharge times requiring high energy. This whitepaper by Eaton Electronics outlines the key differences between supercapacitors and batteries in construction, specifications, capabilities, and applications.

Areas of comparison include:

Calendar and cycle life
Operating temperature
Energy density
Power density and charge rate/discharge time
Efficiency

Components & Materials

Design & Manufacturing

Reliability Security

Transmission & Distribution

Consumer Electronics

Distributed Energy Resources

Non-Renewable Energy
