Overview of electrochemical double layer capacitor
ABSTRACT
The paper [5] shows that Electrochemical liquid double layer capac-
itors (ELCC)are energy storage devices with properties intermediate
between batteries and electrolytic capacitors. The commercial success
of carbon based ELCC is due to their low cost, extremely high cycle life,
and wide range of operating temperatures. They are used mainly for
power backup for electronic circuits. ELCC are also used for load lev-
eling applications in electric vehicles and also pulse power applications.
Nonaqueous electrolytes, such as organic, solid polymers, and inorganic
offer higher energy densities due to the greater decomposition voltages.
