Original Abstract

This paper reports the preparation process of an electrochemical cell consisting of metallic lithium, lithium titanate, and ionic liquid on a MEMS chip surface. Firstly, the MEMS chip is described and the connectivity test of the used pads is performed using voltage contrast imaging. Then the process of electrode preparation using the FIB-SEM technique is described in detail. Special attention is paid to lithium, its degradation during transport into the SEM chamber, and the behavior during ion beam cutting. Finally, a complete battery system was built. It was possible to measure charging/discharging of the model battery system, nevertheless, the functionality was affected by the redeposition of conductive materials on the MEMS surface and charging by an electron beam.
