 Abstract solid polymer electrolytes, SPEs, are a promising alternative to liquid electrolytes for high safety and flexible lithium batteries. Topological polymer electrolytes possess many advantages over linear polymer electrolytes, including higher ionic conductivity, improved solubility, and greater design flexibility. These properties make them ideal candidates for use in next-generation high-safety flexible energy storage devices. This article was authored by Yulu, Qin Huixing, Qin Fengli, and others.
