Production capacity is 10 times, the cost is greatly reduced and the charging time is shortened! I only added a coating?

High performance battery is the key to the launch of electric vehicles. ETH Pioneer PAULBADE is studying how to make them in more cost-effective way. From 0.

6 seconds from 0 to 100 km / h. Top speed 120 km / h. All battery powers.

The first electric racing won in 2013 with traditional internal combustion engine cars. Paulbaade is a 22-year-old mechanical engineering professional student in the Association of the Zurich Federal Institute of Technology, one of the brains behind the battery. Baade and a group of Eth students have spent a year of time to study and fine-tune their super sports cars, participate in the competitions around Europe and have won countless awards.

Our goal is to make the fastest car. The weight of the battery has a big impact, Bad said when reflecting this project. As an undergraduate student at the time, he quickly clearing the lithium-ion battery will be the key to the future of electric cars.

Today, this 30-year-old German is Ethpioneerfellow, and it is necessary to manufacture high performance batteries more economically and efficiently. After all, electric cars are still too expensive, and cannot use internal combustion engines to replace models. The most expensive component is battery.

If we want private transportation to stay away from fossil fuel, Bad said, then we need cheaper, better batteries. Equation Students: The experience of forming a sexual experience to participate in Formulastudentral_made (one of the world's largest engineering competition) has a lasting impact on Baade. Eight years later, in the laboratory in Lu Shili, he enthusiastically reviewed this time.

You can turn your thoughts into reality in the workshop; you can install your own design on your computer. At that time I learned a lot. But there is a problem that he can't stop thinking: How is the battery work? Then, during the master's degree in the master's degree, he began to study the materials used in the battery in depth.

He studied micro and nanotechnology to better understand the internal work of the battery. In his master's thesis, he turned to the famous Lawrence Burkeley National Laboratory, where he studied a special type of titanium dioxide as an anode material. He even built a battery with a glass window to better observe and analyze the diffusion behavior inside the battery, otherwise it is difficult to distinguish.

It is this practical approach to make Baade different. During his study, he has been developing prototypes and experimental devices so that he can immediately test and optimize conditions. In the process of doing this, his focus is increasingly turning to process projects and its actual implementation.

According to Baade, those who don't fully admit or understand this risk will waste time in unrealistic ideas. High-speed coating Baade returned ETH in 2016, pursuing a Ph.D.

in Binnig and Rohrer Nanotechnology Center, which is jointly operated by Zurich Federal Institute of Technology and IBM, where he can study cost-effective lithium ions more deeply. Production of the battery. With the head of the current Eth Knowledge Transfer and the Vice President of the Enterprise Relationship, he has been developing a new solid battery manufacturing process.

The main focus of Baade is the coating process. He built a miniature production facility to accurately simulate and optimize the conditions in real life. Baade uses his own test equipment to demonstrate how to increase the coating speed with typical industrial equipment by applying a thinner coating.

This technique provides impressive potential: it can not only increase production 10 times, thereby greatly reduce production costs, but also shorten the charging time, because thinner coating can achieve faster charging. But this is not all, the battery with solid electrolyte benefits from the faster coating, Baade explains. Today, most lithium-ion batteries contain liquid electrolytes because they have higher conductivity.

But at the same time they are more flammable. BADE's faster coating technology can compensate for lower conductivity by faster coating more quickly. This makes the battery not only more efficient, more cost-effective, and safer.

From the laboratory to the industry, how is the high-speed coating process outside the experiment in a real production facility? This is the problem that Paulbaade will pay attention to the pioneer researcher in the next few years. Our next step is to use the pilot facility to test the scalability of the production process. This is what we are looking for a suitable partner, the engineer added.

Baade is optimistic that the test production process will bring better results in the test facility: "We have been able to produce batteries in our test facilities under quite real-world conditions. Therefore, compared with us, we have a much higher opportunity to expand the scale. Normal laboratory test.
