Thin slice battery technology


According to the report, American drivers drive an average of 30 miles (48 kilometers) a day. Although electric vehicles charge three times as much as the above, there are still many people who are not willing to buy.

This is the so-called “mileage worry” issue, but a team of scientists is trying to resolve the problem.

Walter, a project manager for mobile energy storage systems at the German Industrial Technology Institute, is working with a team to research a new battery that can charge an electric car for 620 miles (1000 kilometers).

The project was launched three years ago when the German Industrial Technology Institute and researchers from ThyssenKrupp Systems Engineering and IAV Automotive Engineering gathered to discuss how to improve the energy density of automotive lithium batteries. They turned their attention to the popular all-electric car Tesla and began research.

One way to achieve a cruising range of 1,000 kilometers is to optimize the battery material and store it for more energy. In addition, there is another way to improve the overall design of the system.

Approximately 50% of the space in each cell is occupied by components such as the outer casing, the positive pole, the negative pole, and the electrolyte (a liquid that moves the charged particles). If you need to install the battery into the car, you need more space because you need to connect the battery to the car's power system. This design wastes space. So the scientists decided to adjust the overall design of the battery. Instead of encapsulating the outer casing of a single battery, the scientists replaced the cylindrical design with a sheet design. The metal sheet is coated with an energy storage material made of powdered ceramic and a polymeric binder. One side of the metal piece is a positive level and the other side is a negative electrode.

The researchers stacked the so-called bipolar electrodes one by one, like stacking sheets of paper, separated by a thin electrolyte, and a material inside to prevent charge shorts. The scientists then packaged the stacked sheets in a size of about 10 square feet (1 square meter) with the upper and lower parts connected to the car's power system.

The ultimate goal of the researchers is to develop a battery system that is the same size as a Tesla or other electric vehicle. More electrodes can be placed in the same space to store more power. Their goal is to test the system on the car by 2020.
