A recently granted patent (Publication Number: US11830673B2) discloses a method for preparing a soft carbon material specifically designed for high-voltage supercapacitors. The method involves alkaline activation and electrochemical activation of an initial soft carbon material with specific characteristics, such as defined carbon layer spacing, crystal plane lengths, and intensity ratios. The resulting soft carbon material is intended for use in high-voltage supercapacitors, offering enhanced performance.
Furthermore, the patent also covers the use of the prepared soft carbon material as a positive electrode material in an asymmetrical supercapacitor, in combination with activated carbon as the negative electrode material. The asymmetrical supercapacitor thus formed is capable of operating at voltages greater than 3.8 V, making it suitable for high-voltage applications. The method outlined in the patent aims to provide a reliable and efficient process for producing soft carbon materials tailored for use in advanced supercapacitor technologies, offering improved energy storage capabilities and overall performance.
