The development of new energy sources is ongoing, thinking different applications that range from the use of different Gadgets to supplant the lithium ion batteries which became very popular between the world of hybrid and electric cars.


One of the projects that have been released in recent days is a Flat Sodio-Níquel drums, which will override or supplement to various formats and designs of rechargeable, offering a high durability in a comfortable design.

Its form is the main advantage highlights above other batteries, similar to a flat disk, conformation which gives physical advantages over others: allows you to deliver up to 30% more energy at low temperatures, a problem that has been reported recently in electric cars, and as a result of frost, for example.
 
Another advantage is the cost of its manufacture, its components are made with aluminum, nickel, sodium chloride, much cheaper than those used in the lithium-ion batteries, and offering the same or better performance.

Nickel in photovoltaic cells reducira cost of solar energy

One of the most promising technologies in search of cheaper solar energy production is being studied by scientists of the University of Toronto (Canada).

And addition, it is expected that this reduction in the cost remains reasonable efficiency photovoltaic cells.

Recently published studies have proven that nickel - a material of low-cost - you can replace the use of gold in certain components of the photovoltaic cells.This change of raw materials would reduce the price cells between 40-80%.

On the application of nanotechnology, has been that the full spectrum of sunlight (visible light and infrared light) in the production of energy can be utilized.This improves performance of solar cells based on components of silicones, since part of the light spectrum is not seized with such technologies.

The team of scientists has reached in initial testing an increase of effectiveness of 5 per cent, and expect reach 10 per cent the commercial launch of this new technology.

The promising results just published were part of an arduous process of research.According to relate some members of the team of research of the University of Toronto, his initial hypothesis that nickel could serve to such processes failed to start.Material nickel blocked the normal flow of current, but then dilucidaron that the incorporation of a nanometer lithium fluoride created a barrier that blocked the original reaction to the expected result.
