PakaLi Battery Laboratory
Main Areas of Research:
  1. Testing of batteries under representative conditions to assess durability in the field,
  2. Battery diagnosis and prognosis using non-invasive and deployable techniques,
  3. Battery packs modeling taking into consideration cell-to-cell variations and inhomogeneities,
  4. Deployed systems state of charge and state of health monitoring,
  5. Battery prototyping and electrode formulation optimization,
  6. Transfer of knowledge from laboratory to real-life applications to facilitate battery engineering, cost estimate, control strategy, and decisions.
‘Alawa Toolbox:

‘Alawa toolbox is a unique toolbox devoted to battery degradation diagnosis and prognosis. The toolbox enables the emulation of the impact of all degradation modes (loss of ion inventory, loss of active material, and kinetic hindrance) on single phased and blended electrodes.

The toolbox is available for free for academic applications and licensing is available for other uses. The toolbox is available in Matlab© and Python. Please visit the ‘Alawa Overview page for more information.

Partnerships and 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.
