Engineering energy dense electrodes (e.g. lithium metal, conversion cathodes, etc.) with solid electrolytes is important for enhancing the practical energy density of solid-state batteries. However, large electrode volumetric strain can...
Commercial lithium-ion (Li-ion) batteries built with Ni- and Co-based intercalation-type cathodes suffer from low specific energy, high toxicity and high cost. Conversion-type cathodes offer an opportunity to overcome such limitations.
