9861091这个小型企业创新研究第一阶段项目将开发用于可充电锂离子电池的更高储能和更低成本的电极材料。锡基氧化物材料表现出非常诱人的可逆电荷存储能力，但具有很高的不可逆容量。提出了一种相关的新材料，它将显著降低不可逆容量，并绕过日本现有的与锡基氧化物电极相关的知识产权壁垒。前驱体的化学成分和反应条件将发生变化，以生产新的候选电极材料。这些材料的成分和微观结构将被确定。将准备测试电池并进行标准电池性能评估，以确定新电极材料的可逆和不可逆容量和循环能力。该项目将开发先进的电极材料，以增加可充电锂离子电池提供的能量。消费应用(无线通信、笔记本电脑、便携式摄像机)以及电动和混合动力汽车的锂离子电池市场增长非常迅速。

9861091 This Small Business Innovation Research Phase I project will develop higher energy storage and lower cost electrode materials for rechargeable lithium ion batteries. Tin based oxide materials have exhibited very attractive reversible charge storage capacities but high irreversible capacities. A related new material is proposed that should significantly reduce the irreversible capacity and circumvent existing Japanese intellectual property barriers associated with the tin based oxide electrodes. Precursor chemistries and reactive conditions will be varied to produce new candidate electrode materials. The composition and microstructure of these materials will be determined. Test cells will be prepared and subjected to standard battery performance evaluations to determine the reversible and irreversible capacity and cyclability of the new electrode materials. This project will develop advanced electrode materials to increase the energy delivered by rechargeable lithium ion batteries. There is a very rapidly growing market for lithium ion batteries for consumer applications (wireless communications, laptop PC's, camcorders) as well as for electric and hybrid vehicle propulsion.
