Our research program focuses on the application of advanced, high-resolution solid-state Nuclear Magnetic Resonance (NMR) methods to characterize structure-property relationships in ion conductors. The two areas of interest are proton-conducting materials for fuel-cell membranes, and inorganic cathode materials for lithium ion batteries. In this proposal, we extend our interest to include two new types of proton conductors, namely solid acids and ionic liquids. All of these materials are linked by the common goal of achieving clean, portable sources of energy. Using solid-state NMR, we are able to probe the molecular-scale mechanisms and process which govern ionic transport; the rate-limiting step in the use of either proton or lithium ion conductors. We expect that these results will impact the design and development of new, improved materials in these areas.

我们的研究项目重点关注应用先进的高分辨率固态核磁共振（NMR）方法来表征离子导体的结构与性质关系。两个感兴趣的领域是用于燃料电池膜的质子传导材料和用于锂离子电池的无机阴极材料。在这个建议中，我们扩展我们的兴趣，包括两种新类型的质子导体，即固体酸和离子液体。所有这些材料都是由实现清洁，便携式能源的共同目标联系在一起的。使用固态核磁共振，我们能够探测分子尺度的机制和过程，支配离子传输;在使用质子或锂离子导体的限速步骤。我们预计这些结果将影响这些领域新的改进材料的设计和开发。
