ELECTRODE FOR LITHIUM ION SECONDARY CELL, METHOD FOR PREPARING PASTE FOR SAID ELECTRODE AND METHOD FOR MANUFACTURING SAID ELECTRODE

摘要

This electrode for a lithium ion secondary cell includes a conductive assistant, a binding agent, and an active material. The conductive assistant includes carbon black and carbon nanofibers. The carbon nanofibers are configured to electrically crosslink the active material with the carbon black so that the carbon nanofibers are fixed by the binding agent to cover a portion of or the entire outer surface of the active material. Moreover, 10 to 100% of the outer surface of the active material is covered by the carbon nanofibers, where 100% represents the entire outer surface of the active material, and electrical crosslinking is achieved due to the carbon black being bound with the carbon nanofibers covering the outer surface of the active material.
