Graphene/TiO2 Nano Composites for Sodium Ion Batteries - Paperback

by C. P. Hemantha Rajapaksha (Author)

Energy is a key factor in day today life for all the people in the world. Decreasing the availability of fossil fuels and the rapid development of the renewable energy sources, energy storage systems become more important. Among various energy storage systems, electrochemical batteries become more promising. Among them Lithium-ion batteries become the most popular due to their excellent properties. High price, safety issues, limited natural deposit are the disadvantages of the lithium-ion battery. A good alternative would be Na since it has similar properties as Li and it is much cheaper as well as abundant. Small life time, law capacity, low voltages and poor cycling stability are the drawbacks associated with the Na ion batteries.Graphene based nano-composite materials exhibit high reversible capacities, better cycle life and good cycling stability. So, graphene/TiO2 nano-composite was used as the anode material for the sodium ion rechargeable battery in this research. This book covers the synthesis of graphene/TiO2 nano-composite and its potential application as an anode in Na-ion rechargeable battery and characterization of the battery is discussed.
