[27.04.2019] Thanks to a special 3D printing process, the range of electric cars can soon reach up to 1,600 kilometers; in a new process, ceramics with lasers can be given a completely new shape.
The range of electric cars is one of the things that most people – who have never driven even with a purely electric car driven – first complain.
Although today's Stromer already have ranges between 200 to 500 kilometers, many people say that they need a longer range. However, most people drive only up to 50 kilometers a day.
3D printers and electric cars are among the fascinating devices that have made it back on the market in recent years.
A team of scientists from Clemson University (South Carolina) has developed a whole new process with the combination of laser and 3D printer.
In order to improve energy storage, scientists have combined lasers and 3D printing in one process, so that ceramics can be brought into completely new forms and compositions. Thus, completely new technological possibilities in material research are conceivable.
On the one hand, hydrogen could be produced more cheaply and, on the other hand, accumulators could be developed which have a higher capacity.
This not only makes cheaper production of hydrogen possible, but also the development of batteries with significantly increased capacity.
Once they come out of the 3D printer from ceramic materials, they are sintered by a laser.
(As sintering is called a process for the production or modification of materials, it is heated, for example, fine-grained ceramic or metallic materials.
However, the temperatures remain below the melting temperature of the main component to keep the product in shape.)
Thus, after printing, the objects do not have to be in an oven, but at the same time, a highly complex component of several different types of ceramics can arise.
Ceramic 3D printing is also important for hydrogen cars
An electrician turns water into hydrogen and oxygen, and hydrogen can be used to power hydrogen cars, for example.
For an electrolyzer four different types of ceramics are needed, which must lie on each other in different positions.
After 25 complete loadings theoretically new tires must be bought
If the new super battery is used, you would theoretically have to buy a new set of tires after 25 complete charges. Because on average, a car tire holds about 40,000 km.
Electric cars could drive more than three times that far
Material researchers assume that ceramic increases the capacity of battery cells. According to the researchers, few changes in the structures and materials are enough with the method to greatly change the capacity of the energy storage.
