A power transfer system includes a power transmission device and a power reception device which are capacitively coupled to allow electrical conduction therethrough in the manner of alternating current. The power transmission device includes an active electrode, a passive electrode, a step-up transformer, and a high-frequency voltage generating circuit. The power reception device includes an active electrode, a passive electrode, and a load circuit. A divider for voltage division based on load capacitances (C1 and C2) is provided between the active electrode and the passive electrode. The active electrode and the passive electrode have respective equivalent capacitances to ground (Ca and Cp) relative to the ground potential. A ground leakage current Ig is minimized by adjusting the values of the respective capacitances in an equivalent circuit so as to satisfy the relationship: C2/C1=Cp/Ca.

A multi-layered band and a method for manufacturing a multi-layered band are disclosed. The multi-layered band comprises a support (1) to hold at least one battery structure (10) formed by overlapped layers including a porous material (11) and two electroactive electrodes (12, 13), one oxidizing (12) and one reducing (13), separated at a certain distance between them and in touch with said porous material (11). The battery structure (10) is configured to be activated upon the addition of a fluid into a given region of the porous material (11) and to provide electrical energy while said fluid impregnates by capillarity the porous material (11). The overlapped layers are constituted by parallel strips extending longitudinally along the length of the support (1), such that said multi-layered band can be cut transversally providing individual batteries of a same or different width each including the porous material (11) and the electroactive electrodes (12, 13).

A method of making an electrode material for a lithium-ion electrochemical cell includes sputtering a wire of metal or metal alloy in an atmospheric plasma to produce activated particles of metal or metal alloy and contacting the activated particles of the metal or metal alloy with particles of a lithium-ion cell active electrode material to produce composite particles in which particles of the first lithium-ion cell active electrode material are adhered to particles of the metal or metal alloy.
