The storage technology promises ten times the energy density offered by lithium-ion batteries but notorious cycling instability remains a concern. Researchers in South Korea may have come a step nearer a solution.Amid intense global competition to identify optimal battery chemistries, lithium-oxygen has stirred interest due to its reported potential to offer ten times more energy density than lithium-ion devices. The claims of the energy storage tech are still undermined, however, by poor cycling stability caused by unstable molecules recombining into heterogeneous and unstable particles, prompting ...Den vollständigen Artikel lesen ...
