Team develops lithium-air battery with an energy density higher than current lithium ion batteries

NIMS and Softbank Corp. have developed a lithium-air battery with an energy density over 500Wh/kg—significantly higher than that of current lithium ion batteries. The research team then confirmed that this battery can be charged and discharged at room temperature. In addition, the team found that the battery developed by the team shows the highest energy densities and best cycle life performances ever achieved. These results signify a major step toward the practical use of lithium-air batteries.
