This investigation highlights the successful synthesis and comprehensive characterization of a robust and reliable copper-based electrocatalyst, with an emphasis on its exceptional performance in hydrogen evolution reaction (HER). Copper oxide, silicon dioxide, and graphite were synthesized and advanced characterization techniques such as XPS, FT-IR, XRD, SEM, and EDS were employed to thoroughly analyze the synthesized materials. The resulting copper nanoparticles supported on silica substrate exhibited a calculated Tafel slope of 37 mV/dec in 0.5 M of H2SO4 solution. Furthermore, a mathematical model based on the Tafel equation and Langmuir-Hinshelwood model was developed to describe the HER reaction kinetics of an electrocatalysts in aqueous solution, which displayed improved HER performance due to its larger active surface area. The composite exhibited high probability for HER in a wide pH range and applied potential, with the composite R2 demonstrating the best stability under reaction conditions. These findings suggest that the copper-based electrocatalyst has significant potential to reduce the cost of producing hydrogen fuel and promote environmentally friendly energy sources.

“…Both Li and cobalt possess a high risk of resource scarcity. [ 31–34 ] The process involves slurry mixing, where a binder, active material, and other conductive additives are mixed to form a slurry. The next step involves coating and drying the slurry in the form of thin sheets onto the current collectors and cutting the electrodes out of it.…”

The increasing adoption of additive manufacturing (AM), also known as 3D printing, is revolutionizing the production of wearable electronics and energy storage devices (ESD) such as batteries, supercapacitors, and fuel cells. This surge can be attributed to its outstanding process versatility, precise control over geometrical aspects, and potential to reduce costs and material waste. In this comprehensive review, major AM processes like inkjet printing, direct ink writing, fused deposition modeling, and selective laser sintering/melting along with possible configurations and architectures, are elaborately discussed for each bespoke ESD. The application of 3D‐printed energy storage devices in wearable electronics, Internet of Things (IoT)‐based devices, and electric vehicles are also mentioned in the review. The role of AM in facilitating the production of solid‐state batteries has also revolutionized the electric vehicle (EV) industry. Recent progress in the field of AM of energy systems with solid electrolytes and potential future directions such as 4D printing to incorporate stimuli‐responsive behavior in 3D‐printed materials, biomimetic design optimization, and additive manufacturing of ESD in a micro‐gravity environment have also been highlighted. Extensive research and continuous progress in this field are expected to enhance the longetivity, industrial scalability, and electrochemical performance of 3D‐printed energy storage devices in future.
