A sputtered platinum nano-interlayer can react with lithium in situ to form a highly conductive lithium–platinum alloy, creating a stable lithium/electrolyte interface, which was atomically resolved by cryo-transmission electron microscopy.
Understanding lithium dendrite propagation in solid-state electrolytes requires highly advanced techniques due to the challenges arising from the lack of characterization techniques to visualize the interior of a solid. In this work, a high-pressure in-situ cell was made to monitor the dynamic changes occurring within an All-Solid-State-Battery under cycling using multiple characterization techniques.
