With global energy demands ever-increasing, allied to efforts to reduce the use of fossil fuel and eliminate air pollution, it is now essential to provide efficient, cost-effective, and environmentally friendly energy storage devices. The growing market for smart grid 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, and 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 the 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 particle size, effectively address these issues.
Advantages of nanomaterials include:
- Nanoscale shortens lithium-ion diffusion length.
- New reactions at the nanoscale are not possible with bulk materials.
- Nanoscale combination with electronic conductive coating improves electronic transport.
- Decreased mechanical stresses due to volume change lead to increased cyclability and lifetime.
- Nanoscale enhances the electrode capability of Li storage.
- The ordered mesoporous structure favors both Li storage and fast electrode kinetic.
- Nano-structure enhances cycle stability.
