Greener approaches to recycle spent electric vehicle (EV) battery in a closed Loop

加拿大最近的目标是到2035年使所有新的轻型轿车和乘用车销售达到100%零排放，这给加拿大的清洁技术行业带来了巨大的经济挑战和机遇。为了实现这一目标以及最近联合国缔约方会议第26届气候首脑会议期间作出的其他承诺，加拿大政府正在包括运输部门在内的所有部门采取行动。为了实现这一目标，迫切需要创新废旧电动汽车(EV)锂离子(Li-ion)电池的绿色回收。拟议的伙伴关系有两个主要目标。与我们的合作伙伴Cnem合作，我们将：(I)利用回收的电池材料开发增值的多功能复合材料、泡沫和无纺布纤维结构，以及(Ii)回收和重复使用废旧电动汽车电池工艺废水中的电解液，这些废水目前无法回收，焚烧时会产生二氧化碳和有毒气体。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，年复合增长率为12.3%。拟议的合作伙伴是多伦多大学、圭尔夫大学和Cnem团队之间的合作。该伙伴关系为研究和发展可持续的电动汽车电池业务提供了重要的框架，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流程。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，并用回收电池材料取代电池生产中的原始材料。此外，该项目还将培训和形成几名高素质的人员，这些人员最终将把他们的专业知识带给加拿大先进的制造、能源和环境工程界以及学术界。

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.
