Li-O2 is a prominent next-generation battery chemistry, with a theoretical energy density of 3504 Wh/kg, an order of magnitude larger than current Li-ion batteries. However, many challenges stand in the way of their adoption such as pore-clogging in the carbon cathode and degradation of both the electrolyte and cathode, resulting in short-cycling lifetimes. In our lab, we are currently working with optimizing the carbon cathode pore structure and surface chemistry to improve cell capacity and with highly concentrated electrolytes to prevent electrolyte degradation and improve cycling lifetimes.
