Canada's recent target to reach 100% zero-emissions for all new light-duty cars and passenger trucks sales by 2035 poses significant economic challenges and opportunities for Canada's CleanTech sector. In order to reach this target, and other pledges set during the Recent United Nations COP26 Climate Summit, the Canadian Government is taking action in all sectors including the transportation sector. Innovation for green recycling of post-use Electric Vehicle (EV) Lithium-ion (Li-ion) batteries is urgently needed to achieve this target. The proposed partnership has two primary objectives. Working with new green recycling of EV battery process of our partner, Cnem, we will: (i) develop value added multifunctional composites, foams, and non-woven fiber structures from recycled battery materials, and (ii) recover and reuse electrolytes in spent EV battery process water effluent which are currently not recycled and generate CO2 and toxic gases upon incineration. The global Li-ion battery market size is projected to grow from USD 41.1 billion in 2021 to USD 116.6 billion by 2030, at a CAGR of 12.3%. The proposed partnership is a collaboration between University of Toronto, University of Guelph and Cnem teams. The partnership provides an essential framework for the research and development of a sustainable EV battery business, including new technology to build cleaner batteries and a cleaner constructive process to recycle EV batteries. These innovations will also result in significant energy savings, reduction in greenhouse gas and toxic gas emissions, minimized wastewater generation and the substitution of virgin materials in battery production with recycled battery materials. In addition, this project will allow for the training and formation of several highly qualified personnel, which will eventually bring their expertise to the Canadian advanced manufacturing, energy, and environmental engineering community, as well as to academia.

到2035年，加拿大最近的所有新型轻型汽车和乘客卡车销售的目标是100％零排放，这对加拿大清洁技术领域构成了重大的经济挑战和机遇。为了达到这一目标，以及最近联合国COP26气候峰会期间设定的其他承诺，加拿大政府正在包括运输部门在内的所有部门采取行动。迫切需要使用后使用后电动汽车（EV）锂离子（Li-ion）电池进行绿色回收的创新来实现这一目标。拟议的合作伙伴关系有两个主要目标。使用合作伙伴CNEM的电动电动电动电池电量过程的新绿色回收，我们将：（i）从回收电池材料中开发增值的多功能复合材料，泡沫和非织造纤维结构，（ii）在过去的电动汽车电池中恢复和重复使用电池中的电解质，目前又不回收二氧化碳和有毒的气体，并产生了浓度和有毒的含量。预计全球锂离子电池市场规模将从2021年的411亿美元增长到2030年的1,166亿美元，复合年增长率为12.3％。拟议的合作伙伴关系是多伦多大学，圭尔夫大学和CNEM团队之间的合作。该合作伙伴关系为可持续电动汽车电池业务的研究和开发提供了一个基本的框架，包括新技术来建造清洁电池和更清洁的建设性过程，以回收电动汽车电池。这些创新还将导致大量节能，减少温室气体和有毒气体排放，最小化的废水产生以及用回收的电池材料在电池生产中替代维珍材料。此外，该项目将允许几名高素质的人员培训和成立，最终将其专业知识带入加拿大高级制造，能源和环境工程社区以及学术界。
