Extremely promising High performance 'Lithium Air Battery' Development in Japan

A February 2009 report by the National Institute of Advanced Industrial Science and Technology (AIST) describes a new type of Lithium Air battery, the salient features of which are as follows:

  • The lithium air battery uses a combination of aqueous and organic based electrolytes
  •  Has achieved a capacity of 50000mAh/g based on an air electrode
  • The lithium fuel battery is comprised of using lithium metal in the form of cassettes or other forms

Here is a schematic of the battery from their publication and a chart showing its performance.
