Developing a safe, low-cost anode free solid-state battery with improved energy density, and longer cycle life

Solid-state lithium metal batteries (SSLBs) are considered the “holy grail” of battery chemistry because of their high capacity and energy density and will remain the dominating technology for the foreseeable future.
However, lithium-metal anodes may trigger dendrites growth at high current, which reduces their cycle life, and safety, making SSLBs more challenging to commercialize. Also, escalating demand and shortage of precious battery raw materials like lithium affect the market value of electric vehicles in Canada.
My research objective is to develop a anode free solid-state batteries with high energy density, longer cycle life, and greater safety which are the key to future decarbonization of transportation.
The absence of lithium metal at the anode side reduces the weight and cost of the battery. Meanwhile, the solid-state electrolyte prevents flammability and dendrite growth, enhancing commercialization. My research outcome will also help address global climate change issues and help Canada transition from an energy provider to an energy innovator.
