The protecting method involves periodically operating a thin-layer battery (11) at its maximum discharge current, and disconnecting the battery as soon as a voltage across it reaches a threshold value greater than its critical voltage for the maximum disch...

The device (20) has a chamber (22) in which a hydrogen-air/methanol-air fuel cell (2) is arranged. An opening is formed on an upper wall (30) of the chamber. The fuel cell is arranged on a lower wall of the chamber such that a surface of the fuel cell expo...

The method involves forming a stack of a cathode collector layer (34) in which lithium ions are inserted, an electrolyte layer (44) and an anode layer (48) of a lithium-ion battery, on a substrate (30), where the cathode layer is made of material i.e. tita...

Formation of lithium-ion battery involves forming insulating layer (12) with opening, over substrate (10); depositing stack (30, 32) comprising layers of cathode collector, cathode, electrolyte and anode, and having smaller thickness than insulating layer;...

Formation of lithium-ion battery involves forming insulating layer (12) with opening, over substrate (10); depositing stack (30, 32) comprising layers of cathode collector, cathode, electrolyte and anode, and having smaller thickness than insulating layer;...

A thin-film lithium-ion type battery is encapsulated by forming, on substrate (40), an active stack (44) having cathode collector layer (46) extending over surface area larger than that of other layers; forming, over the structure, a passivation layer (56)...
