Energy storage options that are reliable, long lasting and affordable are becoming an essential component in developing viable sustainable energy systems. Historically, lead acid batteries have been employed to store excess electrical energy, however, their short lifespan combined with their high maintenance requirements have limited their use. Lithium-ion batteries also have been extensively studied and installed for different applications; however, their high cost, environmental issues and shorter lifespan compared with aluminum-ion (Al-ion) batteries has further hindered their utilization in large-scale applications. Volta Energy Inc. and Lambton College in close collaboration through the proposed project will develop a novel, high-efficiency aluminum-ion battery capable of ultrafast charge and discharge with long cycle life exceeding those of state-of-the-art, commercially available secondary batteries, including lithium-based batteries. . In addition to single cell development and optimization, a series of battery banks, ranging from 1.0 kW to 25.0 kW, 30-minute (0.5 kWh to 12.5 kWh) will be developed and tested under varying operational conditions. Material development and optimization for different battery components, including anode, cathode and electrolyte with emphasis on the last two, will be the primary focused areas. The Lambton College research team will include IRCC Dr. Shahram Karimi, 2 graduate research students and 3 research students. The developed energy storage system into Volta Energy's industrial activities will greatly enhance their ability to serve their existing and future customers while creating economic growth and providing positive environmental impact for Canada.
