Abstract

Read online

The development of potassium-ion batteries requires cathode materials that can maintain the structural stability during cycling. Here the authors have developed honeycomb-layered tellurates K2 M 2TeO6 that afford high ionic conductivity and reversible intercalation of large K ions at high voltages.
