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，预计干净的技术将成为支持加拿大的主要解决方案，以实现格拉斯哥气候包设定的减少温室气体目标。根据所述协议，加拿大的目标是在2030年的二氧化碳（CO2 EQ）排放量下降30％（相对于2005年排放水平）。根据2005年至2019年之间的最新排放数据，必须提出和迅速实施解决方案，以实现这一目标，因为对这种二氧化碳减少目标几乎没有进展。实际上，在2019年，2015年，2010年和2005年，年度排放水平分别分别为730、723、703和739 MEGATONNE CO2 EQ。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为电动汽车锂离子电池天然石墨阳极开发新的涂层技术的迫切需求，该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展Nouveau Monde Phaphite和McGill University之间的持续合作。这个新的涂层过程不需要涂层处理操作，通过成功将行业标准的化石燃料涂料前体用生物化的涂料取代行业标准化石燃料涂料前体，将具有最低的CO2 EQ碳足迹。这些涂料还将以总的储能容量，电池搁板寿命以及在强烈的充电/放电方式下充电/排放的电池容量来增强电池的性能。目前的联盟研究建议有四个研究目标：A =开发一个生物化化学合成过程，以覆盖天然石墨阳极，以增强锂离子电池阳极的性能；扩展在工业环境下最终应用的涂料技术； c =优化锂离子电池涂层的机械性能，以进行上游电化学性能； D =优化使用生物化前体的涂层天然石墨阳极的电化学性能的热处理过程。
