<p>A team of researchers from the Chinese Academy of Sciences Institute of Physics has published a paper in <em>Nature Energy </em>showing a potentially game-changing development in electrolytes for sodium-ion batteries that may accelerate the commercial use of sodium-ion technology.</p>
<p>The team, led by Prof. Hu Yongsheng, claimed the world’s first “zero thermal runaway” in ampere-hour-level sodium-ion batteries. The breakthrough is the development of a self-protecting polymerizable non-flammable electrolyte (PNE), which appears to have largely solved a core safety aspect of batteries.</p>
<p>The breakthrough centers on a transition from passive fire retardation to active thermal blocking from the PNE material, which as a system, employs a three-in-one defense to what the researchers claim eliminates fire and explosion risks.</p>
