Identification of a major factor influencing the cycle life of high energy density lithium-air batteries

By Tech Online Things

NIMS and SoftBank discovered that the cycle life of high energy density lithium-air batteries is predominantly influenced by the ratio of electrolyte volume to electrode areal capacity. The team developed a technique to quantify side reaction products formed and oxygen used in battery electrochemical reactions. Using this technique, the team was able to precisely assess the overall balance between reactants and products, leading to this discovery. These results may facilitate R&D concerning practical lithium-air batteries.
