ionic liquids (emim salts) drastically decreases
as temperature is decreased, as shown in
Figure
6.20
. This is due to the rapid increase in their
viscosity with decreasing temperature. This
trend causes a big problem when
electrochemical devices like batteries and
capacitors that use ionic liquids as electrolytes
are utilized during winter in a cold area. The
development of ionic liquids with excellent
conductivity is eagerly anticipated.
