Investigating the artificial interphase of lithiophilic nanoparticles (Au/Zn) during galvanostatic lithium plating by operando SANS
Anode free batteries are designed to significantly decreases the weight of a cell.They necessitate immaculate reversibility of the charge and discharge process, as no further lithium other than the amount loaded into the cathode is available. Homogeneous plating and stripping of lithium onto a current collector is not readily achieved when plating on e.g. on copper. Lithiophilic metals like Au and Zn can be used to engineer the surface of a current collector, for example through the application of a thin sputtered film (50 nm), with which the lithium forms metallic interphases and hence drastically changes the plating environment. This can be explored further through the electrodeposition of said metals, which can be generated with different size and number density and therefore provide a variety of plating substrate configuration. With this proposal we suggest the investigation of such decorated current collectors with SANS, in order to correlate the electrochemical parameters of the system to the nanoparticle morphology. We believe that neutrons are ideally suited for this experiment, as their weak interaction energy will not negatively impact the ongoing sensitive reactions.
