Canada is on the verge of a clean energy technological revolution. In coming years, clean technologies are expected to become the primary solution to support Canada in meeting its greenhouse gases reduction objectives set by the Glasgow Climate Pack. Under said agreement, Canada aims to reduce by 2030 CO2 equivalent (CO2 eq) emissions by 30% (relative to 2005 emission levels). Based on recent emission data between 2005 and 2019, solutions must be proposed and rapidly implemented to achieve this goal as little to no progress has been achieved toward this CO2 reduction goal. Indeed, in 2019, 2015, 2010 and 2005, annual emission levels were respectively 730, 723, 703 and 739 megatonne CO2 eq. Electric vehicles are one of the avenues to correct this situation. The present Alliance grant research project tackles the urgent need to develop a new coating technology for electric vehicles lithium-ion battery natural graphite anodes that can circumvent current industrial limitations. The proposed Alliance project aims to scale an ongoing collaboration between Nouveau Monde Graphite and McGill University. This new coating process will not require a deagglomeration processing operation, will have the lowest CO2 eq carbon footprint of the market by successfully substituting industry standard fossil fuel coating precursors with biosourced coatings. These coatings will also provide enhanced performance of the battery in terms of total energy storage capacity, battery shelf life, and the capacity of the battery to be charged/discharged under intense charge/discharge regimes. The present Alliance research proposal has four research objectives: A = develop a biosourced chemical synthesis process to coat natural graphite anodes for enhanced performance as lithium-ion battery anodes; scale-up the coating technology for eventual application under industrial settings; C = Optimise the mechanical properties of lithium-ion battery coatings for superior downstream electrochemical performance; D = Optimise the heat treatment process to stabilise the electrochemical performance of coated natural graphite anodes using biosourced precursors.

加拿大正处于清洁能源技术革命的边缘。在未来几年中，清洁技术预计将成为支持加拿大实现格拉斯哥气候包规定的温室气体减排目标的主要解决方案。根据该协议，加拿大的目标是到2030年将二氧化碳当量排放量减少30%（相对于2005年的排放水平）。根据2005年至2019年的最新排放数据，必须提出解决方案并迅速实施以实现这一目标，因为在实现这一二氧化碳减排目标方面几乎没有取得任何进展。事实上，在2019年、2015年、2010年和2005年，年排放水平分别为730、723、703和739兆吨二氧化碳当量。电动汽车是纠正这种情况的途径之一。目前的联盟赠款研究项目解决了迫切需要开发一种新的涂层技术，用于电动汽车锂离子电池天然石墨阳极，可以规避当前的工业限制。拟议的联盟项目旨在扩大新世界石墨公司和麦吉尔大学之间正在进行的合作。这种新的涂层工艺将不需要解聚处理操作，通过用生物来源的涂层成功地替代工业标准的化石燃料涂层前体，将具有市场上最低的CO2当量碳足迹。这些涂层还将在总能量存储容量、电池保存寿命和电池在强充电/放电状态下充电/放电的容量方面提供增强的电池性能。目前联盟的研究提案有四个研究目标：A =开发一种生物源化学合成工艺，以涂覆天然石墨阳极，以增强锂离子电池阳极的性能;扩大涂层技术，以最终在工业环境下应用; C =优化锂离子电池涂层的机械性能，以获得上级下游电化学性能; D =优化热处理工艺，以稳定使用生物源前体的涂覆天然石墨阳极的电化学性能。
