Discovery of a potential solid electrolyte for future all-solid Na-ion batteries

The novel compound Na2-x(CB11H12)x(B12H12)1-x shows a fast ionic Na conductivity of 2 mS cm-1 at room temperature, reaching the superionic regime above 333 K. A low activation energy of 314 meV, in a thermodynamically and electrochemically stable structure, suggest its usage as a potential solid electrolyte in future all-solid Na-ion batteries. The discovery was just published in Journal of Power Sources.
