Univ. of Illinois team develops high-power Li-ion microbatteries that can out-power supercapacitors while retaining comparable energy density
Ragone plot showing the performance of the new microbattery cells (A-H) and conventional power technologies. The energy and power density of our microbattery cells (A–H) at low to high C rates, along with previous microbattery cells having 3D electrodes (MB1 through MB3). The plot also includes the performance range of conventional power technologies and commercial batteries from A123 (high power) and Sony (high energy). Source: Pikul et al. Click to enlarge. Researchers at the University of Illinois at Urbana-Champaign have demonstrated a high-power and high-energy density microbattery constructed from interdigitated three-dimensional (3D) bicontinuous nanoporous electrodes. The new microbatteries out-power…
