Fig. 2 Structure of the anionic borate network polymer[35] (a) The single-ion conducting anionic borate network polymer, ANP-5, developed as an electrolyte for an all-solid-state lithium metal battery; (b) The tetrafluorophenyl borate anion nodes (red) are physically anchored while the lithium cations are mobile throughout the material, acting as the dominant contributors to ionic conductivity. The cis-2-butene-1,4-diol linker (green) facilitates crosslinking to generate a membrane polymer resistant to swelling in the presence of plasticizer; (c) Schematic of a lithium metal battery featuring ANP-5 as the electrolyte
