Science Daily  July 3, 2024 Anode-free batteries possess the optimal cell architecture due to their reduced weight, volume and cost. However, their implementation has been limited by unstable anode morphological changes and anode–liquid electrolyte interface reactions. An international team of researchers (USA – UC San Diego, University of Chicago, University of Korea) showed that an electrochemically stable solid electrolyte and the application of stack pressure could solve these issues by enabling the deposition of dense sodium metal. An aluminium current collector was found to achieve intimate solid–solid contact with the solid electrolyte, which allowed highly reversible sodium plating and stripping […]
