Abstract
The present disclosure relates to a multilayer electrode for a secondary battery. The multilayer electrode for a secondary battery includes: an electrode current collector; a first mixture layer including an active material, a binder, and a single-walled carbon nanotube, the first mixture layer being formed on at least one surface of the electrode current collector; and a second mixture layer including an active material, a binder, and a multi-walled carbon nanotube, the second mixture layer being formed on the first mixture layer. According to the present disclosure, by improving the uniformity of the distribution of the conductive material in the electrode mixture layer, it is possible to prevent the resistance from increasing, and as a result, it is possible to improve the output characteristics of the secondary battery.
