Summary: Silicon is investigated as an active material for the anode of lithium-ion battery due to its higher specific capacity. Metal foams are used as current collectors to achieve low resistance and high capacity, but loose adhesion and loss of electrical contacts with the collector are issues unless the foam is densely compressed. By pyrolysis, silicon reacts with nickel on a nickel foam to form nickel silicide while the selected binder is graphitized, resulting in a conductive and porous anode. The reported silicon-based anode with nickel foam exhibits excellent cycling performance and high retained capacity after 50 cycles under specific discharge/charge conditions.

Summary: Nanocarbons, including carbon nanotubes and carbon nanofibers, were coated on a nickel foam surface via chemical vapor deposition. This unique structure served as a three-dimensional current collector for lithium-sulfur batteries, providing space to accommodate electrode materials. The coated nanocarbons shortened the path of electron transport, absorbed lithium polysulfides, and accelerated their conversion kinetics, thereby suppressing the shuttle effect. Additionally, the rigid framework of the nickel foam constrained the movement of electrode compositions, contributing to the stability of the Li-S batteries.

Summary: The strong interaction between Li and substrate is crucial for improving pore utilization in carbon framework electrodes, thus enhancing their cycle lifetimes. The lithiophilic Ag layer on the substrate promotes confined Li storage in the carbon framework electrode and suppresses top plating, leading to significantly better cycling stability. However, the effectiveness of the Ag layer diminishes when the electrode thickness exceeds a critical value.

Summary: In this study, a composite electrode composed of Ti/TiH2/beta-PbO2_Mn3O4@C was fabricated and investigated for zinc electrowinning. The composite electrode exhibited low overpotential, Tafel slope, icorr, and high voltage stability, outperforming most reported Ti-based PbO2 electrode materials. The excellent catalytic activity can be attributed to the low resistance and porous interlayer of TiH2 nanosheets, as well as the addition of Mn3O4@C micro-flakes to the active layer.
