India, May 5 -- The research team of professor Young-joon Kim(co-author), SKKU Advanced Institute of Nano Technology, announces that they developed high-density electrode design technology that reduces size of lithium-ion batteries through graphene (Gr) coating with Chang-won Park (first author, Ph.D. course) and other researchers.For the existing high-nickel layered anode materials, they have limitations in increasing electrode density due to low strength of particles, and carbon-black materials used as conductive additives are an obstacle to increasing electrode density due to inefficient distribution.As a way to overcome these problems, Gr of fine particles with excellent electronic conductivity is uniformly coated on the surface of th...
