Nanotechnology is providing potential solutions to the high cost and short running times of batteries for electric vehicles and consumer electronics.
Lithium (Li) ion batteries are one of the most common types of batteries being used today – in consumer electronics such as mobile phones and laptops, but also as a replacement for lead acid vehicle batteries. Nanotechnology offers the potential to improve the performance of Li-ion batteries by increasing their capacity and their lifetime (enabling more charge and discharge cycles to take place) and reducing their weight.Nanoparticles coated onto electrolytes dramatically increase the surface area over which current can flow without using any more material. This translates to savings in the weight of the battery.
Super-capacitors are commonly used in commercial power storage applications such as light-rail, electric vehicles and power grids. Carbon nanotubes (CNTs) are being used to improve their performance in terms of capacitance, charge and discharge rates, lifetime and cost.
Graphene aerogel processes are being researched with potential future applications in energy storage. The materials produced are ultralight and porous with good insulating properties. Graphene aerogel lattices have been produced using 3D printing and have high surface area, good electrical conductivity, low density and good mechanical stiffness, suitable for energy and other applications.
