项目摘要

The proposed project targets the development of advanced nanostructured coating materials that address challenges of formation of lithium (Li) dendrite of metal lithium used in next-generation Li ion batteries for energy storage. This innovative research project will take full advantage of Dr. Sun's expertise in nanotechnology for clean energy. It is expected that the techniques developed will significantly protect metal lithium of next-generation Li ion batteries such as solid-state batteries and Li-sulfur batteries. The goals of this research are to apply the advanced atomic layer deposition (ALD) and molecular layer deposition (MLD) coating techniques to deposit various coatings on lithium metal materials to address the challenge of formation of lithium dendrite to significantly increase durability of Li ion batteries. An important aspect is the understanding and control of reactions between coatings and lithium metal. The highly stable and protected Li anode developed in this project will be used to develop the next generation of advanced solid-state battery systems with high energy densities (such as all-solid-state Li ion batteries, Li-S batteries and solid electrolyte-based Li-Air battery). Successful completion of the proposed project will provide benefits to Canadian industry and the nanotechnology community by transferring new knowledge, expertise and technologies to Canadian energy and nanotechnology industries, by accelerating the next-generation Li ion battery commercialization process, and by directly reducing environmental pollution.

拟议的项目针对高级纳米结构涂层材料的开发，这些材料解决了用于储能存储的下一代电池中使用的金属锂形成的锂（Li）树突的挑战。这个创新的研究项目将充分利用Sun博士在清洁能源方面的纳米技术专业知识。预计开发的技术将显着保护下一代电池的金属锂，例如固态电池和Li-Sulfur电池。这项研究的目标是将晚期原子层沉积（ALD）和分子层沉积（MLD）涂料技术应用于锂金属材料上的各种涂层，以应对树突形成的挑战，以显着提高李离子电池的耐用性。一个重要的方面是理解和控制涂料和锂金属之间的反应。该项目中开发的高度稳定和受保护的LI阳极将用于开发具有高能量密度（例如全稳态的Li Ion电池，Li-S Townies和实心电解质的Li-Air电池）的下一代高级固态电池系统。通过将新的知识，专业知识和技术转移到加拿大能源和纳米技术行业，通过加速下一代李离子电池商业化流程，并直接降低环境污染，成功完成拟议项目将通过将新知识，专业和技术转移给加拿大能源和纳米技术行业，从而为加拿大工业和纳米技术社区提供好处。
