In his interview with MaterialsViews, Jaephil Cho talks about his work on new lithium battery anode and cathode materials at the Ulsan National Institute of Science and Technology. Cho, who is affiliated with UNIST’s Interdisciplinary School of Green Energy, describes active coatings on nanoparticle surfaces that can reduce charging times, and using ordered porous silica nanotubes to provide capacities more than ten times higher than graphite.

Cho received his Ph.D in ceramic engineering from Iowa State University in 1995 and now directs investigations at UNIST’s Nano Energy Storage Materials Lab.
