This work proposes acetamide/zinc perchlorate hexahydrate (AA/ZPH) ionic liquid (IL)-polyacrylamide (PAM) polymer electrolytes, here defined as IL-PAM. The novel Zn 2+-conducting IL is able to accommodate trace water and can achieve both high conductivity (15.02 mS cm 1) and alleviation of side reactions (>90% reduction). Cross-linked PAM acts as the three-dimensional framework to suppress dendrites and obtain flexibility.
