Technology Overview
Mounting Energy Storage Demands Fuel the Development of Power Supplies for Extended Battery Life
The miniaturization of microprocessors is redefining the size of electronic appliances such as notebooks, cell phones, and DVD players. Compatibility with these compact devices demands reduction in size of the energy storage devices. The extensive proliferation of electronic devices and increasing integration of functions in a single electronic device, such as Internet access, multimedia, and games, have resulted in increasing demand for power and greater shelf life of a battery. Power management plays an integral role in reducing the size of the energy storage device while simultaneously extending battery life.
Ultracapacitors and battery management integrated circuits are being used to improve battery life management, notes the analyst of this research service. They have the potential to bridge the gap between the energy and power density of a battery, and are largely used in applications that require quick bursts of peak power such as automobiles, cell phones, and laptops.
Emerging Technologies to Improve Energy Density of Electronic Devices
Research on ultracapacitors is heavily concentrated on developing new materials that help increase the surface area of the conductive plates in an ultracapacitor, which would aid in storing more electrical charges, thereby increasing the energy density of the device. Different materials such as carbon aerogel (CA) and other forms of carbon are experimented around the world to improve the conductivity and power density of ultracapacitors.
One of the leading industry participants has come up with a new battery-supercapacitor hybrid that marks the first innovation in the field of lead acid batteries in a long time. This technology aims at providing a higher cycle life for lead acid batteries. It reportedly increases the cycle life by about six times of its current value. Some researchers are arguing about the possibility of combining the two emerging technologies - ultracapacitors and fuel cells, to achieve a reliable power source in automobiles, cites the analyst. This combination could be used with batteries to help in better power management, especially in automobiles. Another participant has developed a new line of DC-DC converters, charge pumps, and power management units that specifically aid in battery management and increase the life of the battery.
