Single-ion BAB triblock copolymers as highly efficient electrolytes for lithium-metal batteries

Development of the classical lithium-ion technology based on liquid electrolytes has been limited to a certain extent by the intrinsic instability of liquid electrolytes and their mechanical properties. A multifunctional single-ion polymer electrolyte based on polyanionic block copolymers consisting of polystyrene segments is now shown to exhibit enhanced lithium-ion transport, mechanical properties and electrochemical stability window.
