项目摘要

This research program will explore newly discovered breakthroughs in battery materials synthesis made in Dr. Obrovac's laboratory. New dry synthesis methods enabling the production battery-grade materials in large amounts with lower cost raw materials, and with no waste and ~100% yields will be explored. This is in contrast to the current production methods that utilize high cost, highly refined raw materials, and produce large amounts of waste water and waste solids. Research will be conducted to utilize these new methods to make commercial-quality materials and in scaling them up for evaluation in commercial format Li-ion batteries. This research has the potential of making batteries with greatly reduced cost and lower environmental impact than today's Li-ion cells. These low cost and low environmental impact methods also enable the creation of battery materials more advanced than today's materials, including particles having precisely controlled internal structure and composition modulation, particle coatings to protect the particles from degradation, and particles having high energy density nanoparticles embedded within their structure. This synthesis flexibility allows researchers to specifically design highly engineered particles with internal chemistries to enable high energy density and long lifetimes. Such materials will be scaled-up for evaluation in commercial format Li-ion batteries. Materials resulting from this research program have the potential to significantly lower battery cost (> 30% cost reduction) and environmental impact, while providing a 15-20% increase in battery energy storage and in lifetime.

该研究计划将探索Obrovac博士实验室中的电池材料合成中新发现的突破。新的干合成方法将探索生产量级的材料，其原材料较低，而无需浪费，〜100％的产量将被探索。这与当前利用高成本，高度精制原材料并生产大量废水和废物固体的生产方法相反。将进行研究以利用这些新方法制造商业质量材料，并将其扩展以进行商业格式的锂离子电池进行评估。这项研究的潜力比当今的锂离子细胞制造了大大降低的成本和降低环境影响的电池。这些低成本和低环境影响方法还可以使电池材料的创造比当今的材料更先进，包括具有精确控制的内部结构和组成调制的颗粒，颗粒涂层，以保护颗粒免受降解以及具有高能量密度纳米粒子嵌入其结构中的颗粒。这种合成的灵活性使研究人员可以专门设计具有内部化学成分的高度工程颗粒，以使高能量密度和寿命长。此类材料将进行扩展以进行商业格式的锂离子电池进行评估。该研究计划产生的材料有可能显着降低电池成本（降低30％）和环境影响，同时提供了电池能量存储和寿命增加15-20％。
