In the case of polypropylene, a polyolefin presents in the automotive industry with fiber reinforcement, it is possible to achieve significant improvements in structural and functional properties, by nanometric inclusions of graphene particles. The addition of graphene enhances its mechanical properties while adding useful life and lightness, making it an interesting option for the sector. ...A material allied to these alternative technologies is graphene, few layers (usually up to 6) of Carbon atoms arranged in a hexagonal and crystalline form in a two-dimensional plane lattice. ...From this innovative and sustainable perspective, achieving weight reduction for structural and non-structural applications, increasing the useful life of materials, and more efficient battery charging requires finding an alternative material capable of filling this gap, with graphene being an excellent candidate to perform the improvement generation of electric vehicles, as lightweight construction and efficiencies will continue to be one of the decisive requirements for electric vehicles.

These nanostructures of 1D, such as nanowires, nanotubes and nanorods, present great potential for enhancing photon absorption, electron transit, and electron collection in solar cells. Graphene is a 2D hexagonal lattice of carbon atoms that is atomically thin. The remarkable mechanical properties of graphene are due to its structure, in which each carbon atom shares three of its four electrons in covalent bonds with its nearest neighbours (sp2 bonds). ...The remarkable mechanical properties of graphene are due to its structure, in which each carbon atom shares three of its four electrons in covalent bonds with its nearest neighbours (sp2 bonds). ...At the same time, the remaining fourth electrons are delocalized across the two-dimensional lattice in an orbital that accounts for the majority of the material’s optoelectronic capabilities. Also, Graphene is noted for having mobility that exceeds that of good metals. Furthermore, since a number of solution-based techniques, such as simple spin coating, may be used to create thin films of graphene a range of compositions can be created utilising low-cost, straightforward, and large-scale processes.

In Figures 3-5, 3D graphene "floats" a first stack of two-dimensional (2D) planar sheets of six-member carbon atoms within the same 3D space as a second stack of graphene oriented at a 90° angle. 3D graphene atomic trap nanomembranes in Figure 3 that ring link six-member carbon atoms together maintain an extremely high vacuum for the greatest buoyancy of a Vacua Dirigible. 3D graphene atomic trap nanomembranes can become an extremely high pressure air beam where no other material is as thin, strong, flexible, electrically conductive, and gastight. ...New graphite ultrathin nanomembranes made of layered graphene make vacuum bags gastight. An electric swing cycle is applied across nanomembranes to reduce air density on selected outside dirigible surfaces to gracefully control buoyancy. ...These thirty-two vacuum bags are manufactured from gastight six-member carbon molecules of graphene arrayed into composite ultrathin nanomembranes. Each surface of the hexagon vacuum bags gastight nanomembranes are individual electric circuits.

In this article, Co9S8 nanoparticles were embedded in reduced graphene oxide (rGO) via a simple anneal approach as high efficient and stable electrodes for SCs. ...The Co9S8 nanoparticles were inserted tightly between the rGO layers due to strong intermolecular forces, preventing the cluster in reduction process of rGO from graphene oxide (GO). The rGO provides the conductive network for Co9S8 and shortens the ion diffusion paths, improving rate performance and enhancing the stability of the electrode material.

Future Technology for Hybrid and Pure Electric Cars 2015-2025

2014-11-01
E-cars are oversupplied and changing in all respects but in this frenzy of birth and death the future is being created with hybrid cars rapidly gaining market share. The sales of pure electric cars are likely to take off in the second half of the coming decade as certain technical and cost challenges are resolved. Toyota and Tesla have hugely benefitted from correct market positioning. Yet, Toyota is now betting strongly on fuel- cell hybrids, and Tesla on mainstream pure electric cars. A vicious shakeout of car and battery manufacturers has commenced with the winners expecting a handsome pay-off. IDTechEx finds that the global sales of hybrid and pure electric cars will triple to $178.9 billion in 2024 as they are transformed. For example, components are becoming integrated; the range extender, as an optional extra, breaks down the difference between pure electric and hybrid. Car manufacturers vertically integrate and collaborate, competing with their suppliers.

Electric Vehicle Forecasts, Trends and Opportunities 2015-2025

2014-10-01
This master report summarizing and forecasting every sector of the EV industry remains unique. It adds new sectors as they become substantial, the latest being car-like micro-EVs homologated as quadricycles in Europe. Many profitable niches are emerging just as the largest major sectors are changing in importance; the industrial and commercial sector is now bigger and much more profitable than e-cars, and is set to remain so for at least eight more years. All components are changing with supercapacitors sometimes replacing or partly replacing batteries and also new types of battery, energy harvesting, power electronics and structure powering growth. Disruptive change is now the norm and the fruits of all this are truly spectacular; including such things as the Marian fast- surface boat that acts as a submarine when necessary, the fixed-wing plane that will stay aloft for five years on sunshine and the flying jet ski.
