Title:
ELECTRODE MATERIAL FOR CAPACITOR
Document Type and Number:
WIPO Patent Application WO/2019/097815
Kind Code:
A1
Abstract:
Provided are a boron-doped nanodiamond having a large specific surface area and a high electrical conductivity, an electrode comprising the boron-doped nanodiamond, and a sensor or an electrical storage device that includes the electrode. The boron-doped nanodiamond is characterized by having a specific surface area of 110 m2/g or more and an electrical conductivity at 20°C of 5.0×10-3 S/cm or more. The boron-doped nanodiamond preferably has a median diameter of 200 nm or less. Additionally, the electrode is characterized by comprising the boron-doped nanodiamond.
