Technology Description:

Oak Ridge National Laboratory (ORNL) is developing an innovative battery design to more effectively regulate destructive isolated hot-spots that develop within a battery during use and eventually lead to degradation of the cells. Today's batteries are not fully equipped to monitor and regulate internal temperatures, which can negatively impact battery performance, life-time, and safety. ORNL's design would integrate efficient temperature control at each layer inside lithium ion (Li-Ion) battery cells. In addition to monitoring temperatures, the design would provide active cooling and temperature control deep within the cell, which would represent a dramatic improvement over today's systems, which tend to cool only the surface of the cells. The elimination of cell surface cooling and achievement of internal temperature regulation would have significant impact on battery performance, life-time, and safety.

Potential Impact:

If successful, ORNL's temperature-regulated Li-Ion cells would increase cooling efficiency and result in better battery performance at substantial system-level cost savings.

Security:

Advances in energy storage management could reduce the cost and increase the adoption of electric vehicles and renewable energy storage technologies, which in turn would reduce our nation's dependence on foreign sources of energy.

Environment:

Improving the reliability and safety of electric vehicles and renewable energy storage facilities would enable more widespread use of these technologies, resulting in a substantial reduction in carbon dioxide emissions.

Economy:

Enabling alternatives to conventional sources of energy could insulate consumers, businesses, and utilities from unexpected price swings.
