An electrical-energy storage device 1 configured for use in a time-varying electromagnetic field, the storage device 1 comprising: an electrode 6 at least part of which is configured so as to hinder the ability of eddy currents induced by said field to circulate therein. Eddy currents may be hindered by forming an electrode having discrete fingers (32, 34, figure 5), and/or by having a thickness below a predetermined fraction of a skin depth at a fundamental frequency. The device may also comprise a casing, such as a foil casing, whose thickness is less than a predetermined fraction of a skin depth at a chosen frequency. The storage device may be used in combination with an inductive power transfer system. |
