Title:
CARBON FIBER, CARBON FIBER MATERIAL PRODUCTION METHOD, ELECTRICAL DEVICE, AND RECHARGEABLE BATTERY
Document Type and Number:
WIPO Patent Application WO/2017/175262
Kind Code:
A1
Abstract:
Provided is a carbon fiber having low contact resistance and high electro-conductivity. The carbon fiber satisfies the following criteria. The diameter of the carbon fiber is 0.5 to 6.5 µm. The length of the carbon fiber is 5 to 65 µm. The carbon fiber has a "waviness". The carbon fiber has protrusions. The protruding height of the protrusions is 20-300 nm. The number of protrusions is 3 to 25 per 1 µm of length of carbon fiber (the length along the carbon fiber). The carbon fiber is provided with carbon black. The primary particle size of the carbon black is 21-69 nm.
