This proposal describes the plan for the development of innovative and environmentally friendly extraction and recycling processes to address the sustainability challenges associated with lithium supply-demand imbalance. Nowadays, electrification of transportation and integration of renewables into electric grid are promoted to combat climate change, both relying on batteries. Lithium ion batteries, a notable generation of rechargeable batteries, are widely utilized in the industry; however, considering the projected increase in lithium consumption, the future availability of lithium resources and their cost is of concern. To resolve the bottleneck for the supply of lithium, urban mining of postconsumer batteries as well as enhancement of existing lithium primary extraction processes is imperative. This work will enable near-term waste valorization in Canadian energy storage industry, as well as long-term objectives of delivering significant environmental benefits and resolving lithium supply challenge. The work plan involves three concurrent Segments focusing on: (I) developing a supercritical fluid extraction process to recycle lithium from lithium ion batteries, (II) improving primary hydrometallurgical extraction processes for lithium, and (III) developing an electrodialysis process for producing high purity LiOH. Preliminary results have established proof-of-principle for these processes. To achieve the goals of the project, a multidisciplinary approach that places at the intersection of supercritical fluid engineering, process engineering and optimization, thermodynamics, electrochemistry, and materials characterization will be followed. This project leverages expertise and funds from Hatch, a knowledge-based pioneer consulting firm and technology and in-plant service provider to the global metals, infrastructure, and energy sectors, in a three-year partnership with the Azimi group at the University of Toronto. This project is highly beneficial for Canada in terms of academic excellence, industrial competitive advantage, and highly qualified personnel, as it creates the opportunity for knowledge based economic and environmental impact as well as enhanced technical edge in the Canadian Minerals, Metals, and Energy sectors.

该提案描述了制定创新和环保提取和回收过程的计划，以应对与锂供需不平衡相关的可持续性挑战。如今，将可再生能源到电网的运输和整合的电气化被提升为依赖电池的气候变化。锂离子电池是一代可充电电池，在行业中广泛使用；但是，考虑到锂消耗的预计增加，锂资源的未来可用性及其成本是令人关注的。为了解决锂供应的瓶颈，必须进行消费者电池的城市开采以及对现有锂初级提取过程的增强。这项工作将使加拿大储能行业的近期废物瓦解，以及带来重大环境福利和解决锂供应挑战的长期目标。该工作计划涉及三个并发段，重点是：（i）开发一种超临界流体提取过程，以从锂离子电池中回收锂，（ii）改善锂的主要水平透射术提取过程，（iii）开发出产生高纯度lioh的电读过程。初步结果已经为这些过程确定了原则证明。为了实现项目的目标，将遵循一种多学科的方法，该方法将遵循超临界流体工程，过程工程和优化，热力学，电化学和材料表征的交集。该项目利用基于知识的先驱咨询公司和技术以及在全球金属，基础设施和能源领域的植物内部服务提供商的专业知识和资金，与多伦多大学的Azimi集团进行了为期三年的合作伙伴关系。就学术卓越，工业竞争优势和高素质的人员而言，该项目对加拿大非常有利，因为它为基于知识的经济和环境影响创造了机会，并增强了加拿大矿物质，金属和能源部门的技术优势。
