A novel high-throughput setup for in situ powder diffraction on coin cell batteries

A new setup for in situ experiments with up to eight electrochemical cells, especially battery coin cells, and the corresponding custom-made in situ cells are presented. The setup is primarily optimized for synchrotron powder diffraction measurements. As a newly constructed experimental setup, the in situ coin 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 LiMn2O4 and LiNi0.35Fe0.3Mn1.35O4 spinel-based positive electrode materials.
