Contradictory to the conventional understanding of solid-state ionics, we find that some organic crystals are highly ion conducting (>10^–4 S/cm at room temperature). Through the microparticles of charge-transfer (CT) complexes, dissociated lithium ions move readily. Fast conduction is observed for a wide variety of compounds that form CT complexes, irrespective of the functional groups. Automatic relationship analysis via machine learning indicates the importance of polarization of the CT complexes for the ionic conduction. The decoupling system, where ion transport is not dominated by the segmental motion of media molecules, paves the way for achieving superionic properties in organic monomeric and polymeric conductors.

固态Li ⁺传导的电荷转移络合物

与传统上对固态离子的理解相反，我们发现某些有机晶体具有很高的离子传导性（室温下> 10 ^–4 S / cm）。通过电荷转移（CT）配合物的微粒，离解的锂离子容易移动。可以观察到形成CT络合物的各种化合物的快速传导，而与官能团无关。通过机器学习进行的自动关系分析表明，CT络合物极化对离子传导的重要性。去耦系统在离子传输不受介质分子的分段运动支配的情况下，为在有机单体和聚合物导体中实现超离子性能铺平了道路。
