Abstract
The adhesion strength as well as the electrochemical properties of LiNi Mn Co O electrodes containing various
conductive carbons (CC) such as fiber-like carbon, vapor-grown carbon fiber, carbon nanotubes, particle-like carbon,
Super P, and Ketjen black is compared. The morphological properties is investigated using scanning electron micro-
scope to reveal the interaction between the different CC and the active material. The surface and interfacial cutting
analysis system is also used to measure the adhesion strength between the aluminum current collector and the com-
posite film, and the adhesion strength between the active material and the CC of the electrodes. The results obtained
from the measured adhesion strength points to the fact that the structure and the particle size of CC additives have
tremendous influence on the binding property of the composite electrodes, and this in turn affects the electrochemical
property of the configured electrodes.
