When high-end sports cars fall in love with supercapacitors
Release time:
Aug 02,2022
Sports car companies such as Rolls-Royce and Lamborghini have announced that they will carry out research and development around high-energy storage technologies such as supercapacitors and apply them to new models. Thanks to the current development of electrochemical basic material science, supercapacitors will have a certain high energy density while maintaining the original high power density characteristics, thereby providing strong power and acceleration for automobiles.
In the past two years, top sports car manufacturing companies have frequently released news on the research and development of new concept models based on supercapacitor energy storage. Rolls-Royce and British technology company have signed a partnership agreement to explore the potential of developing a new generation of high-energy storage technology using new hydrophilic polymers. The latter has applied for a patent on a new polymer superdielectric discovered in the research and is working to commercialize it for use in supercapacitor electrolyte materials and electrical energy storage. Lamborghini claims to be working with the Massachusetts Institute of Technology to develop a new supercar that will use supercapacitors to power it, which is very different from the conventional batteries of the past.
Analysts pointed out that top sports car companies have paid unprecedented attention to the research and development of energy storage devices such as supercapacitors, and the popularity has even surpassed the trend of traditional batteries. Although Tesla's CEO's assertion that lithium batteries will be outdated and supercapacitors are kings is too extreme, it also reflects that the application of supercapacitors in global passenger cars is optimistic.
Prior to this, the main commercial application of supercapacitors in passenger cars was hybrid braking energy recovery. The generated kinetic energy is converted into electricity for use in air conditioners, stereos and other in-vehicle electrical equipment, reducing fuel consumption during actual driving with frequent acceleration and braking. This technology is derived from the Toyota Le Mans LMP1 racing car. It mainly uses the energy storage characteristics of "super capacitors" that can quickly charge and discharge a large amount of power, and are not easy to age after long-term repeated use. In the retrofit market, super capacitors are often used in car audio, and a certain amount of compensation is made during startup or when the vehicle voltage fluctuates, so that the speaker is not affected.
