Christina Lampe-Onnerud will attend the Ernst and Young, Entrepreneurial Winning Women program at the annual Strategic Growth Forum in Palm Springs, November 16, 2017.

Cadenza’s Unique Cell Design

combines the best properties from wound jelly rolls and large prismatic cells and allows for game-changing high energy density at low cost for EV, PHEV and grid markets

Grid Storage

 |  Prismatic Cells

Partnering in today’s grid energy paradigm driving better economics while supporting sustainability goals

FIAT 500e Structure

Electric Vehicles

 |  Li-ion battery

Enabling mass adoption of electric cars through affordable and high-performing battery technology

Cylindrical Jelly Rolls

  • Longer and wider jelly rolls compared to those in 18650 cells
  • These larger jelly rolls lead to significant packaging advantages (higher Wh/L)
  • Lowest cost and highest yield manufacturing process
  • Mature manufacturing with easily accessible mass production tools
  • Use of all state-of-the-art chemistries, power or energy

Novel Housing Support Material

  • Thermally isolating housing enables a closely packed jelly roll configuration without cascading failure
  • Novel and proprietary, non-combustible ceramic fiber material formulations with high levels of fire retardant
  • Thermal isolation is sufficient to allow large jelly rolls with no roll-to-roll runaway

Large Prismatic Cell

  • Configuration allows open jelly roll structure with shared atmosphere
  • Non-expanding cells and no cascading result in space effective and low cost module designs
  • Uses entire jelly roll capacity distribution with no need for sorting
  • Large format size allows easily incorporated low pressure vent and pressure disconnect designs in a space effective way
  • Jelly rolls’ reconfigurable arrays can optimize battery pack to format and capacity
  • Enables low profile packs
