A battery includes a stacked arrangement of electrochemical cells. Each electrochemical cell is free of a cell housing and includes a bipolar plate having a substrate, a first active material layer formed on a first surface of the substrate, and a second active material layer formed on a second surface of the substrate. Each cell includes a solid electrolyte layer that encapsulates at least one of the active material layers, and an edge insulating device that is disposed between the peripheral edges of the substrates of each pair of adjacent cells. Within each cell, an elastic seal is provided between the edge insulating device and the first surface of one cell or the solid electrolyte layer of an adjacent cell.

A battery includes a stacked arrangement of electrochemical cells. Each electrochemical cell is free of a cell housing and includes a bipolar plate having a substrate, a first active material layer formed on a first surface of the substrate, and a second active material layer formed on a second surface of the substrate. Each cell includes a solid electrolyte layer that encapsulates at least one of the active material layers, and an edge insulating device that is disposed between the peripheral edges of the substrates of each pair of adjacent cells. The edge insulating device physically contacts and is directly secured to one of the first surface of one cell and the solid electrolyte layer of an adjacent cell, and is movable relative to, the other of the first surface of the one cell and the solid electrolyte layer of the adjacent cell.

Battery including bipolar cells that have an edge insulating device

A battery includes a stacked arrangement of electrochemical cells. Each electrochemical cell is free of a cell housing and includes a bipolar plate having a substrate, a first active material layer formed on a first surface of the substrate, and a second active material layer formed on a second surface of the substrate. Each cell includes a solid electrolyte layer that encapsulates at least one of the active material layers, and an edge insulating device that is disposed between the peripheral edges of the substrates of each pair of adjacent cells.

Polyacrylonitrile-sulphur composite having increased capacity

A method for manufacturing a solid electrode. To more strongly utilize the intrinsic properties of a porous active material with respect to capacitance and therefore energy density and also rate and high-current capability, in the method, porous active material particles are impregnated using an ion-conducting liquid which contains monomers and/or oligomers in particular and a solid electrode is formed from the impregnated active material particles by adding at least one solid electrolyte. In addition, the invention relates to such solid electrodes and all-solid-state cells.

An assemblage having a thermally insulating switch and a thermal insulator for constituting an electrical conductor passthrough through the thermal insulator. The thermal insulator insulates an inner space from an outer space, the assemblage having inner connector on the side of the inner space and outer connector on the side of the outer space, which are electrically conductively connectable by the switch. The assemblage has a control unit for controlling the thermally insulating switch, a current flowing through the switch is detectable by the control unit, the switch is controllable by the control unit in such a way that the switch is actuatable only in a substantially zero-current state, and the switch is disposed in the thermal insulator in such a way that thermal insulation between the inner connector and the outer connector is accomplished by way of the switch in the open state.
