The scientific objective of the project is to develop the synthesis of alkali metals and silicon monoxide bymetallothermic reduction method. These high energy density materials will be used for the fabrication of newgeneration of rechargeable battery anodes. The project provides for collaboration of two regional researchcenters, the Laboratoire des technologies de l'énergie (LTE) of Hydro-Québec in Shawinigan and the Centre demétallurgie du Québec (CMQ) of Cégep de Trois-Rivières for the development of a high-temperature reactor.The materials studied will be, firstly, magnesium (Mg) and calcium (Ca) for the furnace commissioning; andthen, silicon monoxide (SiO) and lithium (Li) for battery materials synthesis tests. HQ will use new anodematerials for the development of new electrochemical storage systems. The CMQ is interested in metallurgy oflight alloys and wishes to increase its expertise in the manufacturing domain thereof. The project will includethree students, one per year. Expected outcome is to develop two processes one for lithium and one for siliconmonoxide ready for a pilot plant scale. Project finality is the development of high energy density batterieswhich is the key to transport electrification leading to greenhouse emission reduction.

本项目的科学目标是发展金属热还原法合成碱金属和一氧化硅。这些高能量密度材料将用于制造新一代可充电电池阳极。该项目为两个区域研究中心-位于沙维尼甘的魁北克水电公司的能源技术研究中心和位于三河塞格普的魁北克省能源技术中心-提供合作，以开发高温反应堆。然后进行了一氧化硅（SiO）和锂（Li）电池材料的合成试验。HQ将使用新的阳极材料开发新的电化学存储系统。CMQ对轻合金冶金感兴趣，并希望增加其在制造领域的专业知识。该项目将包括三名学生，每年一名。预期成果是开发两种工艺，一种用于锂，另一种用于一氧化硅，准备用于试验工厂规模。项目的最终目标是开发高能量密度电池，这是实现交通电气化以减少温室气体排放的关键。
