Development of inexpensive, safe, and environmentally benign energy storage technologies to replace lithium ion batteries are imperative in order to realize the immense benefits of smart grid systems both in Canada and globally. To create an efficient and reliable smart grid, storing the electricity with an electrochemical energy storage (EES) device and delivering it on demand is a high priority. Recently, aqueous zinc lithium-ion batteries (ZLIBs) have attracted significant attention as an efficient EES system. This technology is completely safe and environmentally friendly, and its cost is much lower than a typical lithium-ion battery. In a ZLIB, metallic zinc is used as the anode which is naturally an abundant metal in Canada and lithium intercalation electrodes, e.g. lithium iron phosphate is used as the cathode. Instead of organic electrolyte of typical lithium-ion battery, aqueous electrolyte will be used which reduces the overall cost, increase safety, and reduce environmental impacts. Currently, Dr. Zhongwei Chen's research group at the University of Waterloo has developed and patented a high performance and durable thick, semi-solid cathode for the ZLIB application. The present proposal entails the optimization of our patented semi-solid cathode, along with scaling up the manufacturing process while simultaneously ensuring quality control and product consistency. Electrode design and strategies will be furtherly investigated to optimize the semi-solid cathode. The strategies consist of optimization of semi-solid cathode physical parameters such as electrode loading and porosity, evaluating the capacity and durability performance in a full-cell, and eventually upscaling the fabrication process to prepare a 30Wh battery prototype for the demonstration. Successful scaling up the fabrication process can be employed by industrial manufacturers to accomplish a commercially viable rechargeable ZLIB for future generation of smart grids. It is expected that the results of the proposed research will provide the potential breakthrough required for successful rechargeable ZLIB commercialization.

必须开发廉价，安全和环境的良性储能技术来取代锂离子电池，以实现加拿大和全球智能网格系统的巨大好处。要创建有效且可靠的智能电网，请使用电化学能源存储（EES）设备来存储电力并按需提供电源。最近，作为有效的EES系统，锌锂离子电池（Zlibs）引起了极大的关注。这项技术完全安全且对环境友好，其成本远低于典型的锂离子电池。在Zlib中，金属锌用作加拿大自然是丰富金属的阳极和锂插入电极，例如磷酸锂用作阴极。将使用水溶液，而不是典型的锂离子电池的有机电解质，可降低整体成本，提高安全性并降低环境影响。目前，滑铁卢大学的陈陈研究小组已开发并为Zlib应用提供了高性能且耐用的较厚，半固定阴极的专利。本提案需要优化我们专利的半固体阴极，同时扩大制造过程，同时确保质量控制和产品一致性。电极设计和策略将进一步研究以优化半固体阴极。这些策略包括优化半固体阴极物理参数，例如电极加载和孔隙率，评估全电池中的容量和耐用性能，并最终将制造过程提高制造过程，以准备30Wh的电池原型用于演示。工业制造商可以成功地扩大制造过程，以完成商业上可行的可充电Zlib，以实现未来的智能电网。 预计拟议的研究结果将为成功充电Zlib商业化提供潜在的突破。
