Imperia Batteries®, a division of Physical Sciences Inc. (PSI), has been awarded a contract from the Naval Air Warfare Center Weapons Division to develop low-temperature, high performance primary and secondary lithium ion batteries.
Low energy density and poor energy retention of commercial batteries at extreme low temperatures limits the warfighter’s effectiveness during missions in the arctic, at high altitudes, or in space. This capability gap must be addressed to improve mission capabilities in these regions. In order to address this capability gap, Imperia Batteries proposes to prototype and deliver primary (non-rechargeable) and secondary (rechargeable) high performance batteries optimized for extreme cold operation. These batteries will be enabled by a previously developed composite separator that has been demonstrated to improve the energy delivered at -40 °C by >3x over conventional technologies. This improvement in ability to deliver energy at cold temperatures will be paired with Imperia’s high energy density cell designs which have >25% (secondary) and >95% (primary) higher energy density than commercial 18650 cells. By both increasing the energy density baseline and improving the ability to deliver energy at low temperatures, Imperia’s low temperature battery solutions will outperform commercial solutions by >3x.
