Abstract

Official abstract text for this publication.

A method and apparatus for in-situ x-ray scatter imaging of battery electrodes. An apparatus includes an X-ray source, a grid, the grid comprising stainless steel wires with uniform spacing, and a cell, the X-ray source directing a beam of energy through the metal grid and components of the cell, the cell blurring a previously sharp projection of grid wires on an image detector. A method includes providing a Spatial Frequency Heterodyne Imaging system, providing a grid, providing a cell, generating X-rays from the Spatial Frequency Heterodyne Imaging system that pass through components of the cell and the grid, and detecting a scatter image from the X-rays.

First claim

Opening claim text (preview).

What is claimed is: 1. A method comprising: providing a Spatial Frequency Heterodyne Imaging system; providing a grid; providing a cell, wherein providing the cell comprises charge cycling of the cell; generating X-rays from the Spatial Frequency Heterodyne Imaging system that pass through components of the cell and the grid; and detecting a scatter image from the X-rays. 2. A method comprising: providing a Spatial Frequency Heterodyne Imaging system; providing a grid; providing a cell, wherein the cell is a chemical reactor including one or more surfaces covered with heterogeneous catalysts undergoing chemical transformations; generating X-rays from the Spatial Frequency Heterodyne Imaging system that pass through components of the cell and the grid; and detecting a scatter image from the X-rays.
