Nanostructured multi-block copolymer single-ion conductors for safer high-performance lithium batteries

Self-assembling, nanophase-separated multi-block copoly(arylene sulfone)s, selectively swelled with ethylene carbonate, provide excellent single-ion conductivity and cycling stability for high-energy lithium/Li[Ni 1/3 Co 1/3 Mn 1/3 ]O 2 batteries.
