 New cathode materials must account for the accommodation of substantial amounts of , and/or LiOH without causing the cathode pores to block and employ suitable catalysts to make the electrochemical reactions energetically practical.Non-aqueous Li–air batteries were demonstrated first.They usually use mixed ethylene carbonate+ propylene carbonate solvents with LiPF6 or Li bis-sulfonimide salts like conventional Li-ion batteries, however, with a gelled rather than liquid electrolyte.
