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.

加拿大最近的目标是到2035年实现所有新轻型汽车和乘用车销售的100%零排放，这对加拿大的清洁技术部门构成了重大的经济挑战和机遇。为了实现这一目标，以及在最近的联合国COP 26气候峰会上做出的其他承诺，加拿大政府正在包括交通运输部门在内的所有部门采取行动。为了实现这一目标，迫切需要对电动汽车（EV）锂离子（Li-ion）电池的绿色回收进行创新。拟议的伙伴关系有两个主要目标。与我们的合作伙伴Cnem的电动汽车电池新绿色回收工艺合作，我们将：（i）从回收的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，以及（ii）回收和再利用目前未回收并在焚烧时产生二氧化碳和有毒气体的废电动汽车电池工艺废水中的电解质。全球锂离子电池市场规模预计将从2021年的411亿美元增长到2030年的1166亿美元，复合年增长率为12.3%。拟议中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重要框架，包括制造更清洁电池的新技术和回收电动汽车电池的更清洁的建设性过程。这些创新还将显著节省能源，减少温室气体和有毒气体排放，最大限度地减少废水产生，并用回收电池材料替代电池生产中的原始材料。此外，该项目还将培训和培养一些高素质的人才，最终将他们的专业知识带到加拿大先进制造业，能源和环境工程界以及学术界。
