Conventional Electrolytes Vs. Lewis-Acidic Polymer Electrolytes

Caption

Contrasting solvation strategies in conventional electrolytes (top-left) and a new class of Lewis-acidic polymer electrolytes (bottom-left). Strong lithium ion coordination and weak anion coordination in Lewis-basic polymers (top-right) leads to a slow conduction of lithium ions and an unfavorably fast conduction of anions. Reduced lithium ion coordination and strong anion coordination in Lewis-acidic polymers (bottom-right) allows for rapid conduction of positive lithium ions -- a property that lithium-ion batteries require to maintain efficiency during discharge/charge cycles.
