Guide: Rolls-Royce, Lamborghini and other sports car companies announced that they will develop research and development around high-energy storage technologies such as supercapacitors for new models. Thanks to the current development of electrochemical basic materials science, supercapacitors will also have a certain high energy density while maintaining the original high power density characteristics, thus providing strong power and acceleration for the car.
