Lockheed Martin Missiles & Space (LMMS), Ultralife Batteries, Inc. (UBI), Eagle Picher Technologies, LLC (EPT), Sandia National Laboratories (SNL) and Rentech, Inc. (RTI) are developing Lithium Ion Solid Polymer Electrolyte (Li-ion SPE) batteries. Under a new Advanced Technology Program (ATP), this team will develop new high-energy density cells and batteries for space and portable electronics applications. These new batteries will utilize new high-energy density anode and cathode active materials developed by SNL and RTI. UBI will incorporate these new materials into an optimized Li-ion SPE electrode laminate. EPT will develop batteries for aerospace applications based on this electrode laminate technology while LMMS will design the battery charge management controller and provide system expertise.
