SBIR Phase I: Carbon-Coated Nano-Structured Electrodes for Next-Generation Lithium-Ion Ultra-Capacitors

这个小企业创新研究（SBIR）第一阶段项目解决了实现高存储容量和高充放电率的关键技术挑战，这是下一代纳米材料基锂离子电极在超级电容器配置中所承诺的。提出的创新方法使用钛酸锂尖晶石（阳极）的单分散纳米级颗粒，单独涂覆结构化碳层，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。提议的设计应该提供显著增强的锂离子通道和涉及整个纳米材料组装的电连接。业界估计，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约为20亿美元；镍氢电池的销售额正在缓慢下降（15亿美元），而锂离子电池的销售额则稳定在20亿美元。这项研究的成功将为具有成本效益的电极材料提供性能上的突破，这将刺激商用锂离子电力设备市场的显著增长。

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.
