Multi‐Scale Characterization Techniques for Polymer‐Based Solid‐State Lithium Batteries

Front Cover: Characterization techniques are essential to explore the interface compatibility and ion transport mechanisms for polymer-based solidstate lithium batteries. In article 2200351, Guanglei Cui, Qian Zhou, Botao Zhang, and co-workers summarize the recent application of multi-scale characterization techniques in polymer-based solid-state lithium batteries, in terms of spectroscopy techniques, microscopy techniques, X-ray techniques, and neutron techniques. Each technique exhibits its own characteristics and advantages, which is suitable for different applications.
