Batteries which use nanowires to increase the surface area of its electrodes are known as Nanowire batteries. Nanowires are structures that have a thickness of constrained or unconstrained length. Some (Silicon, Germanium and Transition metal oxides) are the variations of the lithium-ion battery. These nanowires replace the traditional graphite anode and could potentially improve battery performance. Nanowire battery is a Lithium ion battery, which consists of a stainless steel anode and covered by silicon wires. These devices last for longer duration than the conventional batteries that have applications in laptops, cellphones and other electronic devices.
The rechargeable battery is a promising innovation for reversible power storage in electric vehicles. Current electric vehicles are fueled by lead-acid, NiCd or nickelmetal hydride batteries, which are constrained by their energy density and lifetime. The current Li-ion battery technology, which utilizes LiCoO2 as cathode, lithiated graphite (LiC6) as anode, and LiPF6-organic solvent as electrolyte, has been the most vital power hotspot for compact electronics. However, the high cost and low generation volume because of the shortage of Co are the real obstacles to their wide applications in light duty vehicles. To realize electrochemical energy storage for electric vehicles, scientists are working on a nanowire battery architecture combined with selection of appropriate materials. There are many advantages of using nanowires (NWs) such as NWs have a very large surface to volume ratio to contact with electrolyte; NWs form continuous conducting pathways for electrons through the electrodes; the NW geometry can promote facile strain relaxation during battery operation.
Moreover, NWs has wide range of applications in various fields such as electronics, automotive, healthcare, energy storage, power generation, and many more. North America accounts for lion market share for nanowire battery. Existence of global players in U.S. and Canada is giving lead to North America. Asia-Pacific accounts for second position as strong presence of manufacturing in China and Japan.
