▎ 摘　　要

NOVELTY - The cathode has a conductive carbon layer which is formed at one side of anode current collector and composed of graphene and CNT. A primer layer of specific thickness includes first binder for binding the components of conductive carbon, current collector and cathode mixture layer. The cathode mixture layer arranged on the primer layer includes cathode active material and second binder for binding between the cathode active material particles. USE - Cathode for secondary battery such as lithium secondary battery in battery module of device (all claimed) such as EV, hybrid EV (HEV), notebook computer, tablet PC, cellular phone, MP3, wearable electronic device, power tool, plug-in HEV (PHEV), electric bicycle (E-bike), electrical scooter (E-scooter), and electric golf cart. ADVANTAGE - The conductive carbon composed of graphene and CNT is formed between the cathode collector and the cathode mixture layer, and the electron transport path between the current collector and the cathode mixture layer is secured by forming web structure in the form of a web in the primer layer so that the conductivity is improved. The conductive carbon has a greater anisotropy than conventional conductive materials and can be flatly coated on the current collector. The conductive carbon is advantageous in terms of coating processability and can exhibit excellent adhesion even with a thinner thickness. As a result, it is possible to secure excellent adhesion and conductivity even after discharging, so that the overall performance of the secondary battery can be improved. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacturing method of the cathode for the secondary battery.
