Abstract: A positive electrode for an air battery includes a current collector and a porous layer including an electroconductive material. The current collector includes a base having a first major surface, and a plurality of projections disposed on at least the first major surface of the base. The first major surface of the base is a planar surface. The porous layer is disposed on the first major surface of the base and is in direct contact with the first major surface. The projections are in direct contact with the porous layer in the interior of the porous layer.

Abstract: A direct heat to electricity engine includes solid state electrodes of an electrochemically active material that has an electrochemical reaction potential that is temperature dependent. The electrodes are configured in combination with electrolyte separators to form membrane electrode assemblies. The membrane electrode assemblies are grouped into pairs, whereby each membrane electrode assembly of a given pair is ionically and electronically interconnected with the other. One membrane electrode assembly of a given pair is coupled to a heat source with the other to a heat sink. One membrane electrode assembly of the pair is electrically discharged while the other is electrically charged, whereby the net and relative charge between the two remains constant because of the electronic and ionic interconnection and the difference in temperature of the membrane electrode assemblies, and thereby voltage, results in net power generation.

Abstract: A battery stick for the oval-shaped electronic cigarette comprises a rod shaped housing, and a battery, a control circuit board, and a power button which are accommodated in the housing, wherein an engagement portion for fixed connection with a vaporizer is arranged on an inner wall of the housing proximal to the open end, a mounting frame fitted inside the housing comprises a battery section and a circuit section arranged at one side of the control circuit board with a frame side plate having a same curvature as the inner wall of the housing, an outer border of the mounting frame is arranged with electrodes; the power button is arranged on the power switch of the control circuit board and is received in the first button hole of the housing; and a wedge part is arranged between the inner wall of the housing and the frame side plate.

Abstract: A method produces a laminate-type battery which can suppress short-circuiting even when a positioning guide is used. The method for producing a laminate-type battery having a first current collector layer, a first active material layer, a solid electrolyte layer or a separator layer, a second active material layer, and a second current collector layer laminated in this order, the method includes arranging a first layer along a first contact surface of a positioning guide, rotating the positioning guide, and thereafter arranging a second layer on the arranged first layer along a second contact surface of the positioning guide. The first layer and the second layer are different from each other and include an arbitrary layer selected from the first current collector layer, the first active material layer, the solid electrolyte layer or the separator layer, the second active material layer, and the second current collector layer.
