Abstract

<abstract abstract-type="normal"> <title>Abstract</title> <p>The recent development of <italic>in-situ</italic> liquid stages for (scanning) transmission electron microscopes now makes it possible for us to study the details of electrochemical processes under <italic>operando</italic> conditions. As electrochemical processes are complex, care must be taken to calibrate the system before any <italic>in-situ/operando</italic> observations. In addition, as the electron beam can cause effects that look similar to electrochemical processes at the electrolyte/electrode interface, an understanding of the role of the electron beam in modifying the <italic>operando</italic> observations must also be understood. In this paper we describe the design, assembly, and operation of an <italic>in-situ</italic> electrochemical cell, paying particular attention to the method for controlling and quantifying the experimental parameters. The use of this system is then demonstrated for the lithiation/delithiation of silicon nanowires.</p> </abstract>
