The ever-increasing global energy need and its impact on climate change have motivated intensive research in various renewable energy alternatives. Among these include energy conversion from sources such as the sun and wind, to name a few. In addition, the storage of energy via clean methods is equally important. The use of rechargeable batteries, like lithium ion batteries (LIBs), has proven to be the technology of choice. LIBs are rechargeable, electrochemical storage devices that have gained significant attention and now serve as an integral power source for many of today’s portable electronics and automobiles.
Today, lithium iron phosphate battery systems are very attractive but are hindered by constraints due to its poor lithium ion diffusion dynamics and extremely low electronic conductivity. The battery research group is exploring advanced lithium ion material compositions using nanomaterials such as metallic nanoparticles, carbon nanotubes, carbon nanofibers and graphene. The overarching goal of the renewable energy researchers is to overcome challenges which impede the practical applications of LIBs.
