Lab Equipment

PBL is well equipped for electrode preparation and assembly for different types of half-cells (coin cells, swageloks, PAT-cells) with 30 independent channels for testing. For larger full cells, the laboratory has more than 80 channels available with temperature chambers and state-of-the art safety procedures. Material characterization including x-ray diffraction as well as scanning and transmission electron microscopy, will be done in collaboration with the UHM Material Science Consortium for Research and Education.
