In this work, we propose a facile method for manufacturing a three-dimensional copper foil-powder sintering current collector (CFSCC) for a silicon-based anode lithium-ion battery. We found that the CFSCC is suitable as a silicon-based paste electrode, and the paste-like electrodes are commonly used in industrial production. Compared with flat current collectors, the CFSCC better constrained the silicon volume change during the charging-discharging process. The capacitance of electrodes with CFSCC remained as high as 92.2% of its second cycle after 40 cycles, whereas that of electrodes with a flat current collector only remained at 50%.

Aqueous zinc-ion batteries are an appealing electrochemical energy storage solution due to their affordability and safety. Significant attention has been focused on vanadium oxide cathode materials for ZIBs, owing to their high specific capacity, unique layered or tunnel structures, and low cost. Compared to traditional methods for preparing and assembling electrode materials, direct current (DC) magnetron sputtering allows direct synthesis and uniform deposition on current collectors, offering advantages such as simplicity, mild reaction conditions, and strong film adhesion.

Lithium nitrate (LiNO) stands as an effective electrolyte additive, mitigating the degradation of Li metal anodes by forming a LiN-rich solid electrolyte interphase (SEI). However, its conversion kinetics are impeded by energy-consuming eight-electron transfer reactions. Herein, an isoreticular metal-organic framework-8-derived carbon is incorporated into the carbon cloth (RMCC) as a catalytic current collector to regulate the LiNO conversion kinetics and boost LiN generation inside the SEI.

High-performance liquid chromatography (HPLC) is an invaluable technique that has been used for many decades for the separation of various molecules. The reproducible collection of eluates from these systems has been significantly improved via its automation by fraction collection systems. Current commercially available fraction collectors are not easily customizable, incompatible with other platforms, and come with a large cost barrier making them inaccessible to many researchers.

Water electrolysis recognizes nickel foam (NF) as an effective current collector due to its excellent conductivity. However, recent studies highlighted NF's effect on the efficacy of various electrocatalytic reactions, primarily due to the presence of electroactive chemical species at its interface. In contrast, numerous reports suggested that NF has a negligible impact on overall electrocatalytic activity.

Potassium (K)-based batteries hold great promise for cryogenic applications owing to the small Stokes radius and weak Lewis acidity of K. Nevertheless, energy-dense (>200 W h kg) K batteries under subzero conditions have seldom been reported. Here, an over 400 W h kg K battery is realized at -40 °C via an anode-free and dual-ion strategy, surpassing these state-of-the-art K batteries and even most Li/Na batteries at low temperatures (LTs).
