New single ion conductors were synthesized by grafting the allyl group-containing lithium salt, lithium bis (allylmalonato) borate (LiBAMB), onto allyl group-containing comb-branch polyacrylate or polymethacrylate ethers by means of hydrosilylation. The highest ambient temperature conductivity of 3.5× 10-7 S cm-1 was obtained for a polyacrylate ether-based single ion conductor containing eight EO units in the side chain and five EO units in the ...
