Solar Powered Car

The Sion is the first electric car capable of recharging its batteries from the sun. From now on, you’ll have to worry about range a little less. For only 16.000 € excluding the battery (4000 euros or to rent). With the dynamic integration of solar cells in the body work, we set new measures on the road while convincing with an exceptional design concept. The full efficiency of the Sion is guaranteed by the lightweight design. The exterior is mainly made up of rust-proof polycarbonate. It further is scratch-resistant. The most unique feature in the body work are the solar cells, which are located on the roof, on both sides as on the hood and the rear.

The cockpit  uses a very simple design, showing you how fast you are going and the charging level of your battery. On the left side you can see the number of kilometers generated through the viSono System. After 24 hours, these kilometers will be transferred to the right side, where they are added to the total range left. The Sion copes with the requirements of your daily life: A range of 250km, high power rapid charging, and a sophisticated interior concept with an optional trailer hitch.
The Sion is equipped with 330 integrated solar cells, which recharge the battery through the power of the sun. To protect them from harmful environmental influences the solar cells are covered with polycarbonate. It is shatterproof, light and particularly weather resistant. Under proper conditions the solar cells generate enough energy, to cover 30 kilometers per day with the Sion. This system is called  viSono. Thanks to the technology of bidirectional charging the Sion can not only generate but also provide energy. This feature turns the car into a mobile power station. Using a household plug, all common electronic devices with up to 2,7kW can be powered by the Sion. You can plug in your electronic devices and power them with the Sions battery. Over a type 2 plug the Sion can provide even more power with up to 7,6 kW.
For air filtering  a  special moss is integrated into the dashboard. It filters up to twenty percent of the fine dust particles and has a regulating effect on the humidity inside the Sion. No worries, you do not have to water it. It requires no special care at all.

A Pinch Of Salt Improves Drastically Battery Performance

Researchers at Queen Mary University of London, University of Cambridge and Max Planck Institute for Solid State Research have discovered how a pinch of salt can be used to drastically improve the performance of batteries. Surprisingly, the salt reacted with the sponge in special ways and turned it from a homogeneous mass to an intricate structure with fibres, struts, pillars and webs. This kind of 3D hierarchically organised carbon structure has proven very difficult to grow in a laboratory but is crucial in providing unimpeded ion transport to active sites in a battery. In the study, published in JACS (Journal of the American Chemical Society), the researchers demonstrate that the use of these materials in Lithium-ion batteries not only enables the batteries to be charged-up rapidly, but also at one of the highest capacities.

Due to their intricate architecture the researchers have termed these structures ‘nano-diatoms’, and believe they could also be used in energy storage and conversion, for example as electrocatalysts for hydrogen production.

This metamorphosis only happens when we heat the compounds to 800 degrees centigrade and was as unexpected as hatching fire-born dragons instead of getting baked eggs in the Game of Thrones. It is very satisfying that after the initial surprise, we have also discovered how to control the transformations with chemical composition,” said lead author Dr Stoyan Smoukov, from Queen Mary’s School of Engineering and Materials Science.
