If everything depended on the German Government, a million electric cars would be circulated by the year 2020, but this goal can be achieved only if the capacity of lithium batteries is increased.

Many find it hard to believe that scientists continue to invest time, energy and resources on the optimization of lithium battery for electric cars. It is said to be too expensive, too heavy, which has very short duration and very short range, and those are just some of the image problems confronting the battery in question.

And is that an electric car can have only 100 miles of supply if the driver wants, in addition, open or close the electric windows, activate the navigation system, heating or air conditioning.

Few electric cars use nickel-metal hydride batteries because they generate less energy – two-thirds less! – The lithium ion batteries, hence the hopes are pinned on the latter.

While many experts still find it hard to imagine a way to increase the energy capacity of Li-Ion batteries, as they are called, the industry is not ready to abandon the search. In this field has been investigating for two decades and some promise huge potential findings.

The researchers anticipate the development of a battery with a supply of several thousand kilowatt-hours per kilogram. Even though this battery can only produce a tenth of that energy, it would be three or four times the current generated by the lithium ion battery and would give an electric car the ability to travel hundreds of miles, even if the inside the car in question is equipped with a sophisticated electronic system. However, the obstacles to putting theory into practice is still large.

Jens Tübke experts as the Fraunhofer Institute for Chemical Technology, say that presents challenges at all levels and that the successes of research around the lithium ion battery will only materialize over the next ten years. For its part, Matthias Vetter, a member of the Fraunhofer Institute for Solar Energy Systems is a more realistic possibility of increasing the reach of electric propulsion vehicles in the nearest future hybrid cars. That is, in cars that use batteries and fuel cells.

The success of research around the lithium ion battery will materialize over the next ten years. A car could cover relatively short distances with the impetus provided by the battery and longer distances with the energy of the fuel cell. “Of course, it is necessary to compare the performance of this technology with a combustion engine equipped with a high efficiency extended range,” says Vetter.

The dominant view among scientists is that electric cars that will run through the streets in the coming years will be implemented by lithium ion batteries and promising findings that begin to be integrated into second-generation models.

Electric vehicle with lithium batteries do not emit CO2 or damage the environment if the electricity comes from renewables such as wind, solar photovoltaic and solar thermal or thermal. Wind turbines can supply electricity to electric vehicles in the future and they will also serve to store and regulate the electricity intermittent wind energy sector.
