Abstract: An encapsulated electrode for an electrochemical cell and a method for producing an encapsulated electrode. The encapsulated electrode structure has a first solid-state electrolyte composite (SSE) that has a top surface, a bottom surface, and a peripheral surface. Another layer of the encapsulated electrode structure is the electrode that has a top surface, a bottom surface, and a peripheral surface. Yet another layer of the encapsulated electrode structure is a second SSE that has a top surface, a bottom surface, and a peripheral surface. The first SSE is arranged so as to be attached to the electrode, wherein the bottom surface of the first SSE is attached to the top surface of the electrode. The bottom surface of the electrode is attached to the top surface of the second SSE. Pressure is applied to this stack so that the SSEs deform and encapsulate the electrode.

Abstract: Systems and methods for utilizing one or more spools and/or rollers for the gentle application of a lithium layer onto a separator layer in an electrode stack of a solid-state battery cell to prevent or minimize damage to the conductive layer. In one embodiment, a feeder spool of provides a conductive foil and interleaf stack combination to an application roller. The application roller may then apply the conductive foil onto a separator layer of the electrode stack. An interleaf rewind spool may collect the remaining interleaf material from the conductive foil/interleaf combination once the conductive foil is deposited onto the separator layer. The conductive foil may adhere to the separator layer through a combination of a gravity force pressing the conductive foil and/or surface energy between the conductive foil and the SSE layer, thereby allowing the interleaf rewind spool to pull the interleaf material from the combination.

Abstract: Aspects involve systems and methods for producing an electrode laminate for a battery that includes a stack of a center electrode layer, a solid-state electrolyte (SSE) layer, and carrier film layer (such as an aluminum foil layer), which is removed prior to use in a cell. To laminate the lithium foil layer to the SSE layers, the stack may be fed through a calender press device comprising a first roller and a second roller. The rollers exert a compressive force on the stack to laminate the layers together while also reducing the porosity of the materials within the stack (densifying), enhancing material contact, causing some layers to adhere or otherwise laminate, and/or also causing some layers to partially separate. The pressure applied to the stack by the calender press may correlate to a spacing between the first roller and the second roller, which may be adjustable by a controller.

Abstract: A peeling device for manufacturing of an electrode stack includes an upper wedge and a lower wedge between which the electrode stack is fed after a calendering process. A respective lifting roller may be located at the output ends of each of the wedges, which through coordinated action peels the aluminum layers away from the corresponding layer of the electrode stack. The peeling force, exerted by rollers capturing upper and lower aluminum foil sheets of the stack, may be controlled and relatively uniform, thereby enhancing the ability to peel the foil from the stack while not damaging the relatively delicate remaining layers. The aluminum foil is directed away from the stack along an outer planar surface of the respective wedge where the foil can then be wound around the respective rollers.

Abstract: A light device for attaching to tool members, includes a base, a light device pivotally coupled to the base, and a magnetically attaching device for magnetically attaching the base to the tool members. The base has one or more bars to receive the magnetically attaching device. A coupler may be pivotally coupled between the base and the light device. The base has a spherical member disposed on a stud, and pivotally attached to the coupler. A ring is attached to the light device, and has a spherical member disposed on a pin, to pivotally attach to the coupler. The coupler has two plates to rotatably receive the spherical members of the base and of the ring.

Abstract: A portable scale includes a spring member coupling a grip device to a weighing device, to allow the grip device to be moved relative to the weighing device against the spring member to weigh objects. The grip device includes a fixed jaw having a hook member for attaching to the objects, and a pivotal jaw pivotally attached to the fixed jaw and having a hook member movable toward the hook member of the fixed jaw, to grip the objects, and to allow the objects to be solidly attached to the grip device before conducting a weighing operation. A latch may be used to latch the pivotal jaw to the fixed jaw.
