Integrated High Voltage Lithium Ion Battery - Ultracapacitor Hybrid

Satellite batteries used to store and deliver pulse power for low-earth and geosynchronous orbital missions must function over many years. As power demands increase with expanded functionality, ultracapacitors must be coupled with the batteries to store and deliver the power necessary in short pulses. Giner, Inc. will integrate the two power devices in order to maintain high specific power and specific energy without adding multiple electronic components needed for separate sets of batteries and capacitors. We will develop the electrochemical material processing and composition to produce small integrated pulse-power supplies and explore the relationships between pulse width, duty cycle and specific power and energy. BENEFIT: This Phase I will provide the proof of concept for a power supply capable of expanding the capabilities of the current generation of lithium-ion batteries used in cell phones and portable tools, which demand high power pulses. Short power surges needed in electric vehicles during acceleration will also require combinations of ultracapacitors and rechargeable lithium-ion batteries.
