This Small Business Technology Transfer (STTR) Phase I research project proposes to develop high capacity / high rate nanostructured electrodes and combine them with environmentally benign ionic liquid electrolytes to develop advanced lithium-ion nanobatteries. The proposed work will combine the unique properties of high capacity and high rate capability of nanostructured electrodes with the superior safety-related properties of ionic liquids electrolytes to meet the demands of high energy / power densities, inherently safe operation, and long cycle life for advanced lithium-ion batteries. This research will produce nanostructured electrodes and mate these electrodes with ionic liquid electrolytes to establish the synergism of combining these components to develop batteries with performance and safety exceeding those of the currently available lithium-ion batteries.Lithium-ion batteries represent the current state-of-the-art for rechargeable batteries. However, performance (energy / power densities, safety, and cycle life) of the current lithium-ion batteries is limited by the properties of both electrodes and electrolytes. Improvements in these materials are needed to develop batteries to satisfy the rapidly increasing performance demands for a wide range of applications including consumer electronics, medical electronics, transportation technology, and military/defense. Inaddition to lithium-ion batteries, nanoelectrodes and safe electrolytes in the proposed project will also have a broad impact on the applications to other electronic and electrochemical devices.

这项小型企业技术转移(STTR)第一阶段研究项目建议开发高容量/高倍率纳米结构电极，并将其与环境友好的离子液体电解液相结合，以开发先进的锂离子纳米电池。拟议的工作将结合纳米结构电极的大容量和高倍率能力的独特特性和离子液体电解液的卓越安全相关特性，以满足先进锂离子电池的高能量/功率密度、固有安全操作和长循环寿命的要求。这项研究将生产纳米结构的电极，并将这些电极与离子液体电解液配对，以建立结合这些组件的协同效应，以开发性能和安全性超过目前可用的锂离子电池的电池。锂离子电池代表了当前充电电池的最新技术。然而，当前锂离子电池的性能(能量/功率密度、安全性和循环寿命)受到电极和电解液性质的限制。为了开发电池，需要对这些材料进行改进，以满足消费电子、医疗电子、交通技术和军事/国防等广泛应用对快速增长的性能要求。除了锂离子电池，拟议项目中的纳米电极和安全电解液也将对其他电子和电化学设备的应用产生广泛影响。
