Abstract
The discovery of rechargeable Lithium-Air (Lithium-Oxygen) battery has attracted a lot of
attention in recent years because of its high specific energy (~3620 mAh g -1 ). This type of
battery utilizes ambient oxygen as active material of cathode and lithium metal as an anode.
Number of studies are focused on the practical implementation of Li-air batteries by developing
the appropriate electrode and electrolyte materials. This type of battery can be potentially
implemented into high-performance electric vehicles. However, number of challenges need to
be addressed before the battery can be placed on commercial production. The main problem
limiting the performance of battery is the formation of side products in the reaction of
intermediate oxygen radicals with electrolyte compound. Therefore, the main challenge today
is to find an appropriate electrolyte that will be inert towards all components of the cell.
Number of studies have shown that solid-state electrolytes are more suitable and safer than any
of the electrolytes based on organic or inorganic solvent. This presentation will provide a
review on recent advances in the development of solid-state lithium-air batteries.
