Three McMaster-based investigators will collaborate with Salient Energy to discover, develop and implement new, high performance positive electrode materials for rechargeable zinc-ion intercalation batteries (Zn-ion batteries). This project will directly address the energy storage capacity, capacity retention and cost limitations of current state-of-the-art manganese oxide electrodes that limit their techno-economic viability for energy storage applications. Particularly, Zn-ion batteries are targeted for non-portable applications, such as grid-scale energy storage - a sector predicted to grow to >$15 billion annually by 2030. High performance and affordable batteries are needed for these applications, as they will enable carbon emissions reductions by providing load leveling/storage to facilitate the integration of renewable but variable energy source (wind, solar) into global electricity infrastructures. The interdisciplinary project team will take a targeted and holistic approach to discover, understand and implement new positive electrode materials for rechargeable Zn-ion batteries to address performance, stability and cost challenges. The approach includes: (1) Experimental synthesis, characterization and integration of newly designed positive electrode materials into Zn-ion batteries for performance evaluation; (2) Computational materials discovery, where hundreds of compounds will be screened based on first principles and down selected to guide experimental activities; and (3) in situ characterization of existing and new positive electrode Zn-ion battery materials to understand mechanisms and guide computational/experimental efforts. This project will result in Zn-ion battery materials and technology designs with higher performance and decreased cost. These inventions will be transferred to Salient Energy for pilot-scale production and demonstration, with the intellectual property expected to provide Canada a competitive edge in the manufacture and sale of rechargeable Zn-ion batteries for grid scale energy storage.

三名麦克马斯特大学的研究人员将与Salient Energy合作，发现、开发和实施用于可充电锌离子插入电池（锌离子电池）的新型高性能正极材料。该项目将直接解决当前最先进的氧化锰电极的储能容量、容量保持和成本限制，这些限制了它们在储能应用中的技术经济可行性。特别是，锌离子电池的目标是非便携式应用，比如电网规模的能源存储——到2030年，这一领域预计将增长到每年150亿美元。这些应用需要高性能和价格合理的电池，因为它们将通过提供负载均衡/存储来减少碳排放，从而促进可再生但可变的能源（风能、太阳能）与全球电力基础设施的整合。跨学科项目团队将采取有针对性和全面的方法来发现、理解和实施可充电锌离子电池的新正极材料，以解决性能、稳定性和成本方面的挑战。该方法包括：(1)实验合成、表征并将新设计的正极材料集成到锌离子电池中进行性能评估；(2)计算材料发现，数百种化合物将根据第一性原理进行筛选，并从中选出来指导实验活动；(3)原位表征现有和新的正极锌离子电池材料，以了解机制和指导计算/实验工作。该项目将带来性能更高、成本更低的锌离子电池材料和工艺设计。这些发明将被转移到Salient Energy进行中试规模的生产和示范，其知识产权有望为加拿大在制造和销售用于电网规模储能的可充电锌离子电池方面提供竞争优势。
