Porsche is researching high-performance batteries with silicon instead of graphite anodes in order to achieve a high energy density and fast-charging capability. They will be produced in Europe and initially used in limited-production, high-performance vehicles and in customer motorsport.
Porsche is systematically building up its expertise in the field of cell chemistry for high-performance batteries. In order to meet the extreme demands placed on cell systems in high-performance applications, it is necessary to change the cell chemistry from graphite to silicon anodes. New electrolytes and additives allow operation even at temperatures above 75 degrees Celsius. Such innovative high-performance batteries based on silicon will be used initially in limited-production, high-performance vehicles and in customer motorsport. However, volume and power cells will also benefit from the technological experience gained. Porsche will also ensure that there is a completely European production chain for high-performance batteries.
»The battery cell is the combustion chamber of tomorrow«, says Oliver Blume, Chairman of the Executive Board of Porsche AG. »Our electrified high-performance sports and racing cars place the highest demands on battery technology. To meet these demands, Porsche needs special high-performance cells. Silicon has big potential.« This is because silicon enables a higher energy density and improves energy recovery as well as fast-charging capability.
Additionally, the car manufacturer is planning its own fast-charging stations along the most important European major highways and motorways. These will offer customers a high-quality, brand-appropriate charging experience while complementing the Ionity network. A unique design will showcase the special character of the Porsche fast-charging stations to the outside world.
