Li-air
battery
Lithium–air
(Li–air) batteries have recently received much attention due
to their extremely high theoretical energy densities. The
significantly larger theoretical energy density of the
lithium–oxygen batteries is due to the use of a pure lithium
metal anode and the fact that the cathode oxidant, oxygen,
is stored externally since it can be readily obtained from
the surrounding air. If successfully developed, this battery
could provide an energy source for electric vehicles
rivaling that of gasoline in terms of usable energy density.
However, before Li–air batteries can be realized as
high-performance, commercially viable products there are
still numerous scientific and technical challenges that must
be overcome, from designing the cathode structure, to
optimizing the electrolyte compositions and elucidating the
complex chemical reactions that occur during charge and
discharge.
