Embodiment Construction

[0080] In electrical circuits, batteries and capacitors are used to provide power to other components. However these power supplies work in completely different ways. Batteries use electrochemical reactions to generate electricity. They consist of two electrical terminals (electrodes) separated by an electrolyte. At the negative electrode (anode), an oxidation reaction occurs to produce electrons. These electrons then flow around the external circuit from the anode to the positive electrode (cathode) causing a reduction reaction to take place at the cathode. Oxidation and reduction reactions can continue until complete conversion of the reactants. Importantly though, electrochemical reactions cannot occur unless electrons can flow from the anode to the cathode via an external circuit. This allows the battery to store power for long periods of time.

[0081] In contrast, capacitors store charge electrostatically and cannot generate electricity. conventional capacitors ( ...

Abstract

An apparatus comprises a rigid-flex circuit board and an electrolyte, the rigid-flex circuit board comprising first and second rigid regions physically and electrically connected to one another by a flexible region, the flexible region comprising first and second sections each comprising an electrically conductive layer and a capacitive element, wherein the apparatus is configured such that a chamber is defined between the first and second sections with the respective capacitive elements contained therein and facing one another, the chamber comprising the electrolyte, and wherein the apparatus is configured to store electrical charge when a potential difference is applied between the respective capacitive elements.

Description

technical field [0001] The present disclosure relates to the field of so-called "supercapacitors", and related devices, methods and computer programs, with particular focus on the integration of supercapacitors in flexible printed circuit (FPC) structures. Certain disclosed aspects / embodiments relate to portable electronic devices, in particular so-called handheld portable electronic devices, which may be used by hand (although they may be placed in a stand when in use). Such hand-portable electronic devices include so-called Personal Digital Assistants (PDAs).
