Technology Overview Current Status

  • PowerPanels are integrated structural panels

and Li-Ion energy storage.

  • Sandwich panel construction takes advantage
  • f structural strength of current collectors.
  • COTS battery materials provide state-of-the-art

electrochemical performance.

  • Structure and battery occupying the same

volume doubles the energy density.

  • Many potential applications in vehicles.
  • Developed stacked battery material fabrication

process including electrolyte-resistant adhesive

  • Fabricated several small-scale PowerPanels
  • Demonstrated structural stiffness/strength and

280 Wh/L energy storage after mechanical testing

  • Demonstrated capacity retention for 100 cycles
  • Technical Needs: Vehicle structural design &

scale-up manufacturing.

  • T2M Need: Commercialization partners

Value Added of Structural Batteries

Analysis of Tesla Model S:

  • POWERPANEL has similar size, weight,

and electrical performance as the existing Tesla Model S battery pack.

  • POWERPANEL floor eliminates the need

for rocker panels and cross members

  • Saves 84 kg of aluminum (material

cost alone ≈ $185).

  • Increases interior space by 6 ft3.
  • POWERPANEL floor is dense and sound

absorbing for a quiet ride.

  • POWERPANEL floor gives the vehicle a

low CG and 50/50 weight balance for excellent handling.
