Dendrite‐Free, High‐Rate, Long‐Life Lithium Metal Batteries with a 3D Cross‐Linked Network Polymer Electrolyte

A 3D network gel polymer electrolyte (3D-GPE) is designed for lithium metal batteries and prepared by an initiator-free one-pot ring-opening polymerization technique. This 3D-GPE exhibits an unprecedented combination of mechanical strength, ionic conductivity, and more importantly, effective suppression of Li dendrite growth. The produced lithium-based battery presents long life, high rate, and excellent safety. As a service to our authors and readers, this journal provides supporting information supplied by the authors.
