His work focuses on improving the production processes and properties of activated carbon, particularly for use in electric double layer capacitors.
Latest Patents
One of his latest patents is a process for producing activated carbon for electric double layer capacitor electrodes. This invention provides a method that allows for the easy and inexpensive production of activated carbon that is free from the fusing of carbon particles during activation. The resulting activated carbon has a small diameter, a uniform particle size, and a relatively large specific surface area, making it suitable for commercial applications. The process involves calcining an easily graphitizable carbon material and activating it to achieve an average particle diameter of 0.5 to 7 micrometers and a BET specific surface area of 1500 to 3000 m²/g. Another notable patent involves a raw coke designed for electricity storage carbon material and needle coke. This invention describes a raw coke structure that, when graphitized, results in a product with specific crystallite size ratios, which simplifies the washing operation and reduces the remaining alkali content.
