Abstract

An electrode comprising a crimped carbon fiber having a multilayer structure comprising a hollow structure in the inside, with the inner layer part having a carbon structure containing a herringbone structure and the outer layer part having a carbon structure differing from the carbon structure of the inner part.

Claims

exact text as granted — not AI-modified
1 . An electrode comprising a crimped carbon fiber having a multilayer structure comprising an inner layer part and an outer layer part with hollow structure in the inside thereof, the inner layer part having a carbon structure containing a herringbone structure, the outer layer part having a carbon structure differing from the carbon structure of the inner layer part. 
     
     
         2 . A secondary battery comprising the electrode as claimed in  claim 1 . 
     
     
         3 . An electrode comprising a crimped carbon fiber having a multilayer structure comprising a center part and an outer layer part outside the center part with no hollow structure inside thereof, the center part having a carbon structure containing a shape that carbon layers vertical to the carbon fiber axis are stacked, the outer layer part having a carbon structure differing from the carbon structure of the center part. 
     
     
         4 . A secondary battery comprising the electrode as claimed in  claim 3 .
