摘要:
An inspection system is provided. The inspection system comprises a light source, a grating, a phase shifting unit, an imager, and a processor. The light source is configured to generate light. The grating is in a path of the generated light and is configured to produce a grating image after the light passes through the grating. The phase shifting unit is configured to form and reflect a plurality of phase shifted patterns of the grating image onto an object surface to form a plurality of projected phase shifting patterns. The imager is configured to obtain image data of the projected phase shifted patterns. The processor is configured to reconstruct the object surface from the image data. An inspection method and a phase shifting projector are also presented.

Improved lithium-sulfur energy storage systems can utilizes LixSy as a component in an electrode of the system. For example, the energy storage system can include a first electrode current collector, a second electrode current collector, and an ion-permeable separator separating the first and second electrode current collectors. A second electrode is arranged between the second electrode current collector and the separator. A first electrode is arranged between the first electrode current collector and the separator and comprises a first condensed-phase fluid comprising LixSy. The energy storage system can be arranged such that the first electrode functions as a positive or a negative electrode.

A method of calibrating an inspection system is provided. The method includes contacting a test part with a run-out measurement device and rotating the test part and measuring a first run-out using the run-out measurement device. The method also includes moving the run-out measurement device to a new position and repeating the steps of contacting and rotating the test part to measure a second run-out at the new position. The method further includes using the first and second run-outs to adjust measurements of the inspection system.

Electrolyte additives are described that enhance cycling stability of electrolytes and lithium composite electrodes that prolong cycling lifetimes and improve electrochemical performance of lithium ion batteries. The electrolyte additives minimize voltage fading and capacity fading observed in these batteries by reducing accumulation of passivation films on the electrode surface.
