Abstract
An electrochemical device has at least one carrier substrate (1) provided with a stack (2) of functional layers, including at least one electrochemically active layer (4), which is capable of reversibly and simultaneously inserting ions and electrons and is arranged between two electroconductive layers. The device can be of the electrochromic type. The functionality of at least one of the functional layers, with the exception of one of the electroconductive layers (3,8), is locally inhibited so as to delimit inactive peripheral or non-peripheral regions in the stack (2).
Claims24
An electrochemical device having at least one carrier substrate in contact with a stack of functional layers comprising two electroconductive layers and at least one electrochemically active layer, which is capable of reversibly and simultaneously inserting ions and which is arranged between the two electroconductive layers, wherein
- at least one of the functional layers, with the exception of one of the two electroconductive layers, comprises an active region, and a deactivated peripheral region, where the active region is surrounded by the deactivated peripheral region;
- and
- the deactivated peripheral region has a higher electrical resistivity than the active region.
An electrochemical device having at least one carrier substrate in contact with a stack of functional layers comprising two electroconductive layers and at least one electrochemically active layer, which is capable of reversibly and simultaneously inserting ions and which is arranged between the two electroconductive layers, wherein
- at least one of the functional layers, with the exception of one of the two electroconductive layers, comprises at least one deactivated non-peripheral region surrounded by an active region.
An electrochemical device having at least one carrier substrate in contact with a stack of functional layers comprising two electroconductive layers and at least one electrochemically active layer, which is capable of reversibly and simultaneously inserting ions and which is arranged between the two electroconductive layers, wherein
- a first at least one of the functional layers, excluding one of the two electroconductive layers, comprises a first active region surrounded by a first deactivated peripheral region;
- and
- a second at least one of the functional layers, excluding the one of the two electroconductive layers, comprises at least one second deactivated non-peripheral region surrounded by a second active region.
