Reliable, inexpensive, high-energy density and adaptable power density, low Size, Weight, Power Consumption and Cost (SWaP-C) batteries are essential for space exploration, civil aviation and national defense, as well as for internal and externally carried weaponry and electronic equipment. Energy storage solutions for national security missions must not only provide reliable, energy-dense performance under extreme conditions, but must also be independent from the supply chains originated within the adversary nations.
High
Energy Density Advanced Battery for Aircraft and Spacecraft, Voltogen, is based on innovative manganese
fluoride electrochemical reactions and new modular, highly scalable
and adjustable design. The battery utilizes inexpensive widely
available materials, and is characterized by high current density,
high volumetric energy density, low self-discharge rate, high energy
utilization rate, high number of charge/discharge cycles, wide range
of operating temperatures, as low as -112°F (-80°C) and as high as
248°F (120°C).
The
proposed battery has a real specific energy density of 3140 Wh/kg, 10
times the energy density of the best modern lithium-ion batteries
that are already approaching their theoretical limit, and a specific
discharge current of at least 500 A/kg.
