Ionic systems with enhanced proton conductivity are widely viewed as promising electrolytes in fuel cells and batteries. Nevertheless, a major challenge toward their commercial applications is determination of the factors controlling the fast proton hopping in anhydrous conditions. To address this issue, we have studied novel proton-conducting materials formed via a chemical reaction of lidocaine base
具有增强质子传导性的离子系统被广泛认为是燃料电池和电池组中很有前途的电解质。然而,对其商业应用的主要挑战是确定控制无水条件下快速质子跳跃的因素。为了解决这个问题,我们研究了通过利多卡因碱与一系列酸的化学反应形成的新型质子传导材料,这些酸具有多种质子活性位点。从环境和高压实验数据中,我们发现所检测盐的导电性能存在根本差异。另一方面,DFT 计算表明,阳离子结构内的内部质子跳跃强烈影响电荷载流子的迁移路径。
