Electrodes for electrochemical energy storage devices with optimised output and energy storage

Electrode layer composite comprises first layers (6, 8) containing electrode material and second layers (7, 9) containing electrode material. The first layers have a higher specific capacity than the second layers, while the second layers have a higher power density or current carrying capability than the first layers. Independent claims are also included for the following: (1) Electrochemical storage element with the above electrode layer composite; and (2) Method for the production of the electrode layer composite.
