Off-grid communities and industrial sites, such as those in Northern Ontario, often rely on diesel powered generators for both primary and back-up power. These generators contribute to air and noise pollution and emit greenhouse gases. e-Zinc is commercializing a low cost, safe and environmentally benign, zinc-air battery which can be integrated into micro-grids with solar/wind power and are designed to deliver energy for long-durations (> 24h). These systems can eliminate the need for diesel generators altogether. The gravity driven design of e-Zinc's battery reduces pumping and overall storage costs but leads to a unique challenge in that the air-breathing cathodes must operate under large hydrostatic pressures. In collaboration with the Pope Group at the University of Waterloo, e-Zinc aims to design a completely new cathode design which can resist even higher pressures as they scale up the size of their system. Expanding on the team's initial work which showcased a promising proof-of-concept air-cathode, the team will investigate new methods to reduce electrode flooding, more stable catalysts and improve the throughput of the novel laser-based production approach used to create the cathodes from a biomass-derived polymer resin. The success of this project will help e-Zinc to more rapidly scale their system and to improve energy utilization efficiency of micro-grids - in particular for off-grid communities. In addition to the expected economic benefits and increased job opportunities that will arise in manufacturing the new air cathodes and scaled zinc-air batteries, the expected reduction in pollution and greenhouse gases are expected to positively impact all Canadians - in particular those in off-grid communities.

离网社区和工业场所（例如安大略省北部的社区和工业场所）通常依靠柴油发电机提供主要和备用电源。这些发电机会造成空气和噪音污染，并排放温室气体。 e-Zinc 正在将一种低成本、安全且环保的锌空气电池商业化，该电池可以集成到太阳能/风能微电网中，旨在长时间（> 24 小时）提供能源。这些系统可以完全消除对柴油发电机的需求。 e-Zinc 电池的重力驱动设计降低了泵送和总体存储成本，但也带来了一个独特的挑战，即呼吸空气的阴极必须在较大的静水压力下运行。 e-Zinc 与滑铁卢大学 Pope Group 合作，旨在设计一种全新的阴极设计，当他们扩大系统尺寸时，该设计可以承受更高的压力。该团队的初步工作展示了一种有前途的概念验证空气阴极，该团队将扩展该团队的初步工作，研究减少电极溢流的新方法、更稳定的催化剂以及提高用于制造阴极的新型激光生产方法的产量来自生物质衍生的聚合物树脂。该项目的成功将帮助 e-Zinc 更快地扩展其系统并提高微电网的能源利用效率 - 特别是对于离网社区。除了制造新型空气阴极和规模化锌空气电池带来的预期经济效益和增加的就业机会外，预期污染和温室气体的减少预计将对所有加拿大人产生积极影响，特别是那些离网的加拿大人社区。
