Porous Power Signs $1.41M CRADA with Oak Ridge National Laboratory to Commercialize a New Lithium-Ion Battery Manufacturing Process

Porous Power Technologies LLC, a developer of highly porous, laminable separator membranes for lithium-ion batteries, has signed a $1.41 million cooperative research and development agreement (CRADA) with Oak Ridge National Laboratory to accelerate the SYMMETRIX production process. (Earlier post.)

The SYMMETRIX production process reduces the cost of free-standing separator membranes by coating SYMMETRIX separator film directly on to electrodes. In addition to reducing overall battery cost, this film can:

  • Extend the life and high-power capacity of lithium-ion batteries.
  • Minimize heat generation in batteries so more energy is available for application use, which enables the batteries to operate at a safer, cooler temperature.
  • Allow batteries to charge 50% faster than equivalent batteries with traditional separators.

Porous Power has paired its separator material with a new manufacturing technique that will enable companies to produce dozens of batteries in the same time it currently takes to produce a single cell.

This dramatically alters the cost equation and paves the way for mass production of more affordable lithium-ion car batteries. This project with Oak Ridge will accelerate the development of the patent-pending SYMMETRIX production process and confirm the safest, most cost-effective materials to use in these batteries.

ORNL selected this project, in part, because it answers all four of the key technology barriers cited in the DOE Vehicle Technologies Program 2008 Annual Progress Report: cost, performance, abuse tolerance and battery life.
