A primary barrier preventing repetitive fast charging of Li-ion batteries is lithium metal plating at the graphite anode. One approach toward mitigating Li metal deposition is the deliberate modification of the graphite anode surface with materials demonstrating high overpotentials unfavorable for Li metal nucleation, such as Ni or Cu nanoscale films. This research explores Ni and Cu surface coatings at different areal loadings (3 or 11 μg cm−2) on the electrochemistry of graphite/LiNi0.6Mn0.2Co0.2O2 (NMC622) type Li-ion batteries. Extended galvanostatic cycling of control and metal-coated electrodes in graphite/NMC622 pouch cells are conducted under high rate conditions. Based on the overpotential of Li deposition on metal foil, both Ni and Cu treatments were anticipated to result in reduced lithium deposition. The higher metal film loadings of 11 μg cm−2 Ni- or Cu-coated electrodes exhibit the highest capacity retention after 500 cycles, with mean improvements of 8% and 9%, respectively, over uncoated graphite electrodes. Li plating quantified by X-ray diffraction indicates that the metal films effectively reduce the quantity of plated Li compared to untreated electrodes, with 11 μg cm−2 Cu providing the greatest benefit.

“…However, for Cu samples, the bFB is used. Here, a negative potential applied at the Al 2 O 3 /3DCu protects the surface by avoiding the oxidation and dissolution of the Cu due to the interaction with the mediator species. , The SPECM investigation of the catalytic activity of Al 2 O 3 /3DCu photoelectrodes was done using the SG/TC mode. , In this mode, the signal intensity correlates with the concentration of the species generated at the 3DCu and, thus, with the activity of the surface beneath the UME …”

Photo-Responsive Doped 3D-Printed Copper Electrodes for Water Splitting: Refractory One-Pot Doping Dramatically Enhances the Performance

3D-printed electrochemical systems and devices are highly interesting due to their customizability and point-of-need fabrication capabilities. The most common and accessible fused deposition modeling (FDM) often requires modification of the resulting material, usually by atomic layer deposition or electrodeposition. We show doping of FDM-printed copper electrodes with metal oxide crystals via a one-pot preparation step. We will show that such doped materials have dramatically enhanced photoelectrochemical properties. We utilize the fact that the copper/polylactic acid filament requires the sintering of 3D-printed parts as a post-printing procedure to form electrically conductive devices useful for electrochemical applications. Thermally stable refractory materials (i.e., graphite or Al2O3) are mandatory for the sintering process to support the 3D-printed structure. Such refractory materials can dope the surface of the 3D-printed electrode in a one-pot process. For example, here, the Al2O3 microcrystals dramatically affect the measured photocurrents and the performance of the photoelectrodes. The detailed investigation using scanning photoelectrochemical microscopy to image electro- and photoelectrochemical-generated H2 and O2 offers spatially resolved information about the photoelectrochemical activity. Therefore, the presented work will have profound implications for the design and fabrication of metal-based electrochemical and photoelectrochemical 3D-printed devices because the doping method can be transferred to other metals and refractory materials.

Local electrochemical deposition is a type of electroplating used to plate metal locally or form metal objects using electrochemical principles at a short distance from the working electrode. In this work, deposition of the copper spot was modelled using COMSOL software and experimentally tested in copper sulfate electrolyte using soluble copper anode. The working capillary diameter was 4 mm and the interelectrode distance was 5 mm. The deposited copper of 100 µm height was investigated using the 3D-profilometry technique. The geometry of deposited metal was found to be in good accordance with the COMSOL model. The inclusions of anodic sludge were responsible for the surface inhomogeneity of the deposited copper.
