At the Power Day conference organized by Volkswagen and dedicated to the development of traction batteries, Porsche also shared its plans. It turned out that the sports car manufacturer is actively working on batteries with a silicon anode that will quadruple the energy density.
Modern lithium-ion batteries use graphite as an anode. However, if you replace it with silicon, you can get batteries with improved performance – that’s what Porsche is working on. So far, the details of the technology are kept secret, but it is already known that the new generation power sources will operate on a fundamentally different “chemistry” and will be able to maintain optimal parameters even at temperatures above 75 degrees Celsius.
The production chain of such batteries will be entirely located in Europe – obviously, we are talking about future Volkswagen “gigafactories”. First, the batteries will be used in customer racing programs and on limited electric vehicles, and only then it will come to mass models. Porsche expects silicon-anode cells to dramatically increase energy storage density and charging speeds.
At the same time, the company announced the development of a network of branded charging stations – they will be installed along major European highways. Each station will be equipped with several charging points (from 6 to 12) with a capacity of at least 350 kilowatts, as well as a recreation area, which can be accessed from a smartphone. The stations will complement the existing Ionity points, but will have a different design.
And on the eve of Volkswagen talked about plans to radically reduce the cost of batteries by simplifying and unifying them. Cells of a new type will appear in 2023, and by 2030 they will be used on 80 percent of electric cars. In the initial version, such batteries will be 50 percent cheaper than existing ones, on average (mainstream) – 30 percent.
