ACTIVATED CARBON, CARBON STARTING MATERIAL FOR ACTIVATED CARBON, METHOD FOR PRODUCING ACTIVATED CARBON, AND METHOD FOR PRODUCING CARBON STARTING MATERIAL FOR ACTIVATED CARBON
Document Type and Number:
WIPO Patent Application WO/2016/031423
Kind Code:
A1
Abstract:
Provided is activated carbon which is capable of achieving sufficiently high electrostatic capacitance under low temperature conditions if used in an electric double layer capacitor or in a lithium ion capacitor. Specifically provided is activated carbon for capacitors, which has a sodium content of 20 ppm or more but less than 4,000 ppm, a phosphorus content of 100 ppm or more but less than 2,000 ppm, and an average particle diameter of 1 μm or more but less than 50 μm as determined by a laser scattering particle size distribution measuring instrument, and a BET specific surface area of 1,400 m2/g or more but less than 3,300 m2/g.
