Abstract: A cathode configured for a solid-state battery includes a body having grains of inorganic material sintered to one another, wherein the grains comprise lithium. A thickness of the body is from 3 ?m to 100 ?m. The first major surface and the second major surface have an unpolished granular profile such that the profile includes grains protruding outward from the respective major surface with a height of at least 25 nm and no more than 150 ?m relative to recessed portions of the respective major surface at boundaries between the respective grains.

Abstract: A roll-to-roll sintering system for wide inorganic tape material may include a spool on which is wound a continuous tape material comprising a green tape material and a backing layer, a take-up reel, and a heating station including at least one furnace. The heating station is configured to receive an unwound length of the continuous tape. The heating station further includes a first curved section such that the continuous tape material is bent through a radius of curvature of 0.01 m to 13,000 m, and at least two rollers defining the first curved section over which the continuous tape material is bent. The heating station is controlled to provide at least a portion of the heating station with an air free atmosphere, that being at least one of vacuum, hydrogen, or helium.

Abstract: A manufacturing system includes a tape advancing through the manufacturing system and a station of the manufacturing system. The tape includes a first portion having grains of an inorganic material bound by an organic binder. The station of the manufacturing system receives the first portion of the tape and prepares the tape for sintering by chemically changing the organic binder and/or removing the organic binder from the first portion of the tape, leaving the grains of the inorganic material, to form a second portion of the tape and, at least in part, prepare the tape for sintering.

Abstract: Two transferred electron devices are provided in a thermally coupled relationship. One transferred electron device is operated above threshold voltage as an amplifier or oscillator, while the other transferred electron device is operated below threshold voltage so as to supply heat to the first device, to compensate for any operating temperature changes and thereby maintain the first device at a substantially constant temperature.
