Partnerships & Funding:
PBL has been a partner with various research institutions in government, industry, and academia, in the U.S. and abroad. Current funding sources include the Office of Naval Research, the Department of Interior Bureau of Reclamation, SAFT Batteries (France), Element Energy, ACCURE battery intelligence (Germany), the Defence Science and Technology Group (Australia), and Trevi Systems. Previous funding included the U.S. DOE’s Office of Energy Efficiency and Renewable Energy (through the Idaho National Laboratory), the Department of Transportation (via the Electric Vehicle Transportation Center), the Air Force Research Laboratory (through the Hawai‘i Center for Advanced Transportation Technologies), and the Hawai‘i Renewable Energy Development Venture funds.
Present and Past Collaborations (in alphabetical order):
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.
