Synthesis, Structure And Properties of Electrochemically Active Nanocomposites
Abstract
The need for miniaturization of high-speed and high-power devices to meet consumer demand for easy access and portability has placed stringent demands on the energy requirements. There is therefore a need for high-energy density lightweight energy storage systems to meet these challenging demands of portable devices. The Li-ion battery since its commercialization by Sony in 1990 is still the major choice of rechargeable energy source for portable consumer electronic devices such as camcorders, laptops and cellular phones. Since 1990 however, the materials systems used in Li-ion batteries have considerably matured. The area of cathodes has witnessed considerable research activity and a number of systems have been identified with potential capacities for use in high-energy systems. In the area of anodes however, graphite still appears to be the material of choice. There is therefore a need to identify alternative electrochemically active anode systems better than carbon that could be competitive with existing and advanced cathode systems of the future while at the same time meeting the challenges posed by high-energy devices.
