With global energy demands ever increasing, allied to efforts to reduce the use of fossil fuel and eliminate air pollutions, it is now essential to provide efficient, cost-effective, and environmental friendly energy storage devices. The growing market for smart grit networks, electric vehicles (EVs) and plug-in hybrid electric vehicles (PHEVs) is also driving the market for improving the energy density of rechargeable batteries.
Rechargeable battery technologies (such as Li-ion, Li-S, Na-ion, Li-O2 batteries) and supercapacitors are among the most promising power storage and supply systems in terms of their widespread applicability, and tremendous potential owing to their high energy and power densities. LIBs are currently the dominant mobile power sources for portable electronic devices used in cell phones and laptops.
Although great advances have been made, each type of battery still suffers from problems that seriously hinder the practical applications for example in commercial EVs and PHEVs. The performance of these devices is inherently tied to the properties of materials used to build them. Carbon nanomaterials will play an important role in all aspects of the energy sector:
Lithium-ion batteries have shown great promise in portable electronics and electric vehicles due to their long lifespan and high safety. However, hurdles relating to the sluggish dynamics and poor cycling stability restrict the practical application. Carbon nanomaterials such as graphene and carbon nanotubes (CNTs), due to their significantly decreased particles size, effectively address these issues. Advantages of nanomaterials include:
Carbon nanomaterials are also finding application in Lithium-sulfur (Li-S) batteries, sodium-ion batteries, lithium-air batteries, magnesium batteries and paper, flexible and stretchable batteries. Carbon nanomaterials have been widely investigated as effective electrodes in supercapacitors due to their high specific surface area, excellent electrical and mechanical properties. Applications of Carbon nanomaterials in batteries and supercapacitors include:
