Electrode and electrochemical device including the same |
| abstract |
The present invention relates to an electrode and an electrochemical device including the electrode, and more particularly, to an electrode current collector; A first electrode active material layer formed on at least one surface of the electrode current collector and including a first electrode active material having a particle size of 1 to 20 m; And a second electrode active material layer formed on the first electrode active material layer and including a second electrode active material having a particle size of 10 to 100 mu m, and an electrochemical device including the electrode. According to the present invention, an electrode active material layer including a relatively small-sized electrode active material is formed on the lower layer, and the resistance can be reduced by lowering the diffusion resistance in the electrode active material layer in the vicinity of the current collector, , An electrode active material layer containing a relatively large-sized electrode active material is formed on the upper layer so that the side reaction can be reduced by lowering the specific surface area in the electrode active material layer near the separator where the side reaction is vigorous, The lifetime performance can be improved. |
