Lithium Polymer Batteries: Porous SnO2/C Nanofiber Anodes and LiFePO4/C Nanofiber Cathodes with a Wrinkle Structure for Stretchable Lithium Polymer Batteries with High Electrochemical Performance (Adv. Sci. 17/2020)

In article number 2001358, Jae‐Kwang Kim, Sang Mun Jeong, Jung Sang Cho, and co‐workers successfully demonstrate an approach for high‐performance stretchable batteries via 1D nanofiber active materials, stretchable gel polymer electrolyte, and wrinkle structure electrode. The stretchable full‐cell battery in this study shows the highest energy densities as compared to the other stretchable batteries reported previously.
