Abstract

Electrochemical capacitors (ECCs) are a promising technology for applications where high power at low voltage is needed for short periods (I) of time. Examples where ECCs are of interest include pulsed communication handsets, distributed power supplies such as in PCs, and electrical and hybrid vehicle power trains. ECCs are energy storage devices, blrt unlike batteries they can be charged and discharged at very high rates for thousands of cycles. In many situations a battery and ECC are being envisioned as a hybrid power supply. The battery provides the traditional energy storage function while the ECC provides the high rate (or pulsed power) function which is becom- ing common for many advanced electrical systems. Commercially available capacitors (film, ceramic, electrolytic) are capable of high rate charge/discharge cycles, but they store relatively little energy at a low voltage and hence have only limited capability to meet the demands of pulsed power systems which are designed to operate at low voltage.
