An energy storage device sits within a trench with electrically insulated sides within a substrate. Within the trench there is an anode, an electrolyte disposed on the anode, and a cathode structure disposed on the electrolyte. Variations of an electrically conductive contact are disposed on and in electrical contact with the cathode structure. At least part of the conductive contact is disposed within the trench and the conductive contact partially seals the anode, electrolyte, and cathode structure within the trench. Conductive and/or non-conductive adhesives are used to complete the seal thereby enabling full working electrochemical devices where singulation of the devices from the substrate enables high control of device dimensionality and footprint.

A module includes a first member that is a battery or a gas tank in which pressure fluctuation happens along one axis direction, a pair of second members, the second members being arranged on end portions of the first member in the one axis direction, respectively, and a binding member binding the first member and the second members while pressurizing them. The binding member is formed as fiber-reinforced plastic (FRP) containing fiber and resin is revolved. The FRP includes a base fiber layer with a fiber direction along a revolution direction, and a reinforcing fiber layer with a fiber direction different from that of the base fiber layer. The reinforcing fiber layer has a non-overlapping portion between both end portions in a revolved state. The non-overlapping portion is positioned in a region facing the first member.
