Abstract: An electrical bypass device for a battery is provided for isolating and bypassing a defective battery module made up of secondary cells to allow the battery to continue operating under slightly degraded conditions. The bypass device comprises a first actuator and a second actuator which trigger when a module becomes defective. The actuators each comprise a first, second and third terminal. The first and second terminals are electrically connected to the output terminals of the secondary cells, and the third terminal can be switched between the first and the second terminal. Switching over of the third terminal of an actuator occurs when the actuator is triggered. Triggering (intentional or inadvertent) of one of the actuators leads automatically to triggering of the other actuator if the latter has not triggered.

Abstract: A high voltage capacitor design is provided that provides improved performance. The high voltage capacitor includes a stack of mechanically bonded capacitor cells, which in one variant utilize a separator formed of two layers of paper. In one version, the high voltage capacitor may be used as a capacitative voltage divider.

Abstract: A high voltage capacitor design is provided that provides improved performance. The high voltage capacitor includes a stack of cold welded capacitor cells, which in one variant utilize a separator formed of two layers of paper. In one version, the high voltage capacitor may be used as a capacitative voltage divider. A sealed high voltage capacitor is processed using selectively sealable ports disposed on the capacitor, though which fluids are introduced and expelled.

Abstract: An electrochemical cell having a cell package made of a metallic material to allow the cell package to be sealed by welding, even when contaminated. The electrochemical cell further includes an electrode cell stack and a metallic cell package having a base portion and a lid portion which are welded to each other (peripheral seam) to define an enclosure. The cell package includes a first section for receiving the cell stack and a second section having an inlet port and a degassing port which communicate with the first section. The lid portion is welded to the base portion to form a weld seam located between the first and second sections to seal off the first section from the second section. The weld seam extends from the peripheral seam on a first side of the cell package to the peripheral seam on a second side of the cell package.

Abstract: According to an exemplary embodiment a polyvinylidene diflouride homopolymer and solvent, such as acetone, are mixed together to form a solution. The solution is coated on a porous electrode. The coated electrode is immersed in a bath, such as denatured Ethanol, thereby creating a porous membrane on the electrode. The membrane coated electrode is then dried. After drying membrane coated electrode is placed opposite another porous electrode with the membrane positioned substantially between the first and second electrodes. The membrane is compressed between the electrodes dry bonding the membrane with the other electrode thereby forming a good physical bound. Alternatively the membrane may be formed on both electrodes and the membranes are then compressed between the electrodes thereby dry bonding the first and second electrodes together. In yet another embodiment the membrane may be formed separately then compressed between the electrodes thereby dry bonding the membrane with the two electrodes.

Abstract: A cell contains a device for inserting a stack of electrodes and holding it in place. This device enables a stack of electrodes to be inserted and held in place in a container having a base and receiving a lid, the stack having two opposite plane faces and the container having two opposite plane walls. The device comprises two tapes connected by a central blade and is disposed between the plane faces of the stack and the plane walls of the container. The two tapes form elastic cylindrical sectors, advantageously parabolic in shape, with the concave side facing outwards when fitted.
