A novel high-throughput setup forin situpowder diffraction on coin cell batteries

Abstract

A new setup forin situexperiments with up to eight electrochemical cells, especially battery coin cells, and the corresponding custom-madein situcells are presented. The setup is primarily optimized for synchrotron powder diffraction measurements. As a newly constructed experimental setup, thein situcoin cell holder was tested for positional errors of the cells and the reliability of the diffraction as well as electrochemical measurements. The overall performance characteristics of the sample holder are illustrated by measurements on LiMn2O4and LiNi0.35Fe0.3Mn1.35O4spinel-based positive electrode materials.
