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.

该小型企业创新研究(SBIR)第一阶段项目解决了在超级电容器配置中实现下一代基于纳米材料的锂离子电极所承诺的高存储容量、高充放电速率方面的重大改进的关键技术挑战。提出的创新方法使用单分散的纳米级钛酸锂尖晶石颗粒(阳极)，分别涂覆有结构的碳覆盖层，并压实成适当的结构，用于薄膜混合超导体原型的性能测试。拟议的设计应能极大地增强对锂离子的获取，并提供涉及整个纳米材料组装的电气连接。业内估计，一次电池市场的价值超过130亿美元，电子应用、玩具和游戏以及电话的二次电池市场的价值约为20亿美元；虽然镍氢电池的销售额正在缓慢下降(15亿美元)，但锂离子电池的销售额稳定在20亿美元。这方面的成功将为具有成本效益的电极材料提供性能上的突破，这将刺激商业锂离子动力设备市场的显著增长。
