This Small Business Innovation Research (SBIR) Phase I project addresses the key technical challenge for realizing the substantial improvements in high storage capacity, high charge-discharge rates promised by the next generation of nanomaterial-based lithium-ion electrodes in supercapacitor configurations. The innovative approach proposed uses mono-disperse nano-sized particles of lithium titanate spinel (anode), individually coated with a structured carbon overlayer, and compacted into appropriate structures for performance testing in a thin-film hybrid superconductor prototype. The proposed design should provide dramatically enhanced access to lithium ion and electrical connectivity involving the entire assembly of nanomaterials. Industry estimates the value of the primary battery markets over $13 billion, secondary battery markets for electronics applications , toys and games, and telephones around $2 billion; while NiMH cell sales are slowly falling ($1.5 billion), lithium-ion cells are holding steady at $2 billion. Success here will provide a breakthrough in performance for cost effective electrode materials that will stimulate significant growth in the commercial lithium-ion power device markets.

这项小型企业创新研究（SBIR）I阶段项目解决了实现高存储容量，高电荷放电率的重大改善，下一代基于纳米材料的锂离子电极在超级电容器配置中所承诺的。拟议的创新方法使用钛酸锂（阳极）的单分散纳米大小的颗粒，分别用结构化的碳覆盖层覆盖，并将其压缩到适当的结构中，以在薄膜混合型杂交超级导管原型中进行性能测试。所提出的设计应极大地增强涉及整个纳米材料组装的锂离子和电连接性的访问。行业估计，主要电池市场的价值超过了130亿美元，电子应用，玩具和游戏的二级电池市场以及电话约为20亿美元；虽然NIMH细胞销售正在缓慢下降（15亿美元），但锂离子细胞的稳定为20亿美元。这里的成功将为具有成本效益的电极材料提供绩效的突破，这将刺激商业锂离子电源设备市场的显着增长。
