Abstract
An electrical or electrochemical cell, including a cathode layer, an electrolyte layer, and an anode layer is disclosed. The cathode layer includes a first material providing a cathodic electric transport, charge storage or redox function. The electrolyte layer includes a polymer, a first electrolyte salt, and/or an ionic liquid. The anode layer includes a second material providing an anodic electric transport, charge storage or redox function. At least one of the cathode and anode layers includes the ionic liquid, a second electrolyte salt, and/or a transport-enhancing additive.
