  • New 3D microbatteries stand up to industry standard thin-film counterparts

    Portrait of postdoctoral researcher Pengcheng Sun

    The batteries that power today’s microdevices have very thin electrodes that save space, but do not pack the punch needed for today’s wireless technologies. In response, Illinois postdoctoral researcher Pengcheng Sun and his colleagues have developed a way to make more powerful microbatteries using different materials and fabrication techniques.
