After finishing his MRes degree in Nanoscience and Nanotechnology in 2020, Jien joined the NanoManucfacturing group led by Dr Michael De Volder for his PhD. The focus of his project is to improve the packing of active materials and the transport of ionic species within battery electrodes. To this end, a bottom up approach will be undertaken to sequentially assemble primary particles into higher order structures that can bring about improved battery stability and greater energy density.
