电化学能量存储是本世纪的主要社会挑战之一。基于液体电解质的经典锂离子电池技术在过去的二十年里取得了很大的进步，但液体电解质固有的不稳定性导致了安全问题。固体聚合物电解质将是解决这些安全问题，小型化和提高能量密度的完美解决方案。然而，如在液体中一样，锂离子携带的电荷的比例很小（
Electrochemical energy storage is one of the main societal challenges of this century. The performances of classical lithium-ion technology based on liquid electrolytes have made great advances in the past two decades, but the intrinsic instability of liquid electrolytes results in safety issues. Solid polymer electrolytes would be a perfect solution to those safety issues, miniaturization and enhancement of energy density. However, as in liquids, the fraction of charge carried by lithium ions is small (
