Monitoring of lithium plating by neutron reflectometry

New insights into the solid–liquid interface exploiting neutron reflectivity

“…[13] An alternative approach to study surfaces which are not transparent to neutrons, is to support a thin film of the material on a transparent substrate. This has been reported for an increasing number of metal systems including Fe [14,15], Ti [16][17][18], Cu [19][20][21][22][23][24][25], Ni [26][27][28], Al [29,30] and Au [31][32][33][34]. Steel [35] remains a challenge with the overall deposited composition replicated, but the metallurgical aspects are not necessarily typical of bulk steel (see section 2.3 below).…”

“…A couple of other interesting electrode surfaces studies look at the plating of Li onto a Cu electrode [22] and the use of an alumina capping layer on Si as a pseudo-SEI. [29] This protects the Si film from the electrolyte, whilst allowing Li inclusion with a pore collapse and regrowth mechanism.…”

The Concept of Fractals in the Structural Analysis of Nanosystems: A Retrospective Look and Prospects

“…This circumstance is a result of several important contributions. First, such objects as thin films [262,263,349,359,369], lipid bilayers [155,191,255], nano-sized laponite disks [162,193] and some others are quasi-two-dimensional ones. Second, these are polymer systems in the statistical coil state under -conditions [315].…”

Neutron Sources at the Frank Laboratory of Neutron Physics of the Joint Institute for Nuclear Research

“…The RF power comes from klystrons-RF power amplifiers of a 10 To improve the performance of lithium batteries, a series of experiments on neutron reflectometry (GRAINS reflectometer) to study the electrochemical interfaces of liquid electrolyte/solid electrode have been carried out. From the specular reflectivity analysis, the formation of a solid-electrolyte interphase (SEI) on the surface of the electrode (Cu) has been concluded, and the lithium electrodeposition and growth of parasitic dendritic structures during the operation of an electrochemical cell have been tracked [21].…”
