项目摘要

This proposal covers basic studies in three areas: 1) Combinatorial and high-throughput materials science methods where hundreds of samples are prepared and tested in parallel; 2) Fundamental understanding and elimination of degradation in Li-ion batteries leading to batteries well-suited to electric vehicle applications and 3) a new project now beginning on rechargeable Zn-air batteries. The Discovery Grant (DG) supports fundamental studies and basic science while Dahn's other funding supports more applied studies.Jeff Dahn's NSERC/Industrial Research Chair (IRC) program supports applied studies that continually use the combinatorial and high-throughput materials science methods developed during the DG work. New methods involving the use of a newly acquired combinatorial solutions handling robot will be developed under DG funding and used to characterize positive electrode materials for Li-ion batteries. The impact of new electrode materials and electrolyte additives on lithium-ion battery lifetime and cycle life will be studied using newly developed, unique in the world, methods. Presently, the way that 99% of such battery chemistry changes affect cycle and calendar life of Li-ion batteries is not well understood and this is where the DG research will play a major role. Zn-air batteries have the largest volumetric energy density of any commercially available battery technology, however, they are not presently rechargeable. Even a tiny Zn-air hearing aid battery, which is largely made up of the battery casing, has a measured energy density of 1800 Wh/L, compared to 700 Wh/L for the best Li-ion cells. We have started a small project in rechargeable Zn-air batteries which will continue under DG funding.
这项建议涵盖三个领域的基础研究:1)组合和高通量材料科学方法,其中数百个样品被制备和并行测试;2)从根本上了解和消除锂离子电池的退化,从而制造出适合电动汽车应用的电池;以及3)一个关于可充电锌空气电池的新项目现已开始。探索基金(DG)支持基础研究和基础科学,而丹的其他资金支持更多的应用研究。Jeff Dahn的NSERC/工业研究主席(IRC)计划支持继续使用DG工作期间开发的组合和高通量材料科学方法的应用研究。在DG的资助下,将开发使用新获得的组合解决方案处理机器人的新方法,并用于表征锂离子电池的正极材料。新电极材料和电解液添加剂对锂离子电池寿命和循环寿命的影响将使用新开发的、世界上独一无二的方法进行研究。目前,99%的电池化学变化对锂离子电池循环和日历寿命的影响方式尚不清楚,这是DG研究将发挥重要作用的地方。锌空气电池的体积能量密度是所有商用电池技术中最大的,但目前它们不能充电。即使是一个很小的锌空气助听器电池,主要由电池外壳组成,测得的能量密度为1800WH/L,而最好的锂离子电池的能量密度为700WH/L。我们已经开始了一个可充电锌空气电池的小项目,该项目将在DG的资助下继续下去。
