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

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 […]

Chemists develop polymer cathodes for ultrafast batteries

In the face of the surging demand for lithium-ion batteries and limited lithium reserves, scientists are searching for alternatives to the lithium technology. Russian researchers from Skoltech, D. Mendeleev University, and the Institute of Problems of Chemical Physics of RAS have synthesized and tested new polymer-based cathode materials for lithium dual-ion batteries. The tests showed […]
