“…Design for reusability is an upgraded step to record design data, recover previous data and use previous design knowledge for reusability of already used parts and products. By focusing on design for reusability guidelines, environmental impact can be significantly reduced because of reduction in material waste and landfill waste, and it also reduces material and energy consumption by using existing components (Bras and McIntosh, 1999; Sungjemmenla et al , 2021). Guideline “Optimize part orientation for build time and roughness” needs to give more priority.…”

Purpose Additive manufacturing (AM) technologies have tremendous applications in industries owing to their unique advantages. Sustainable AM (SAM) is gaining significance because of lightweight structures, lattice geometries and customized parts for industrial applications. To facilitate design for SAM, design guidelines from AM and environment viewpoints are to be analyzed. In this context, this paper aims to present the analysis of SAM guidelines. Design/methodology/approach This work divides 26 identified SAM guidelines into four categories. Grey axiomatic design was used to calculate the weights of guidelines categories. Further, the grey technique for order preference by similarity to ideal solution was used as a solution methodology to prioritize the SAM guidelines. Findings The top identified guidelines are “Design for reusability” and “Optimize part orientation for build time and roughness.” Implementing proper design guidelines leads to many sustainable benefits such as minimum material consumption, energy consumption and emissions. Originality/value This study would facilitate Am product designers to deploy prioritized guidelines for enhancing the effectiveness of the additively manufactured product with sustainability benefits. The prioritized guidelines would guide the AM product designers to take maximum advantage of the AM process by deploying design for AM and design for environment guidelines. This study contributed a structured approach for design engineers and practitioners to deploy guidelines during the early stages of product design to ensure AM feasibility with minimal environmental impact.

“…53,54,67 Due to their high electronegativity and small atomic diameter, nitrogen atoms are able to improve battery performance by binding to sulfur species and facilitating sulfur immobilization. 59,68,69 For the ZIF-8derived MPC cathodes reported by Eng et al, higher nitrogen doping was found to lead to superior long-term cycling stability and Coulombic efficiency despite having lower electrical conductivity and reaction kinetics. 54 Moreover, it was observed that varying the carbonization temperatures of the MOF precursors (800-1000°C) effectively tuned the nitrogen doping, with lower carbonization temperatures resulting in higher nitrogen contents.…”

Room-temperature sodium-sulfur batteries (NaSBs) are promising candidates for next-generation large-scale energy storage solutions. However, the wellknown polysulfide shuttling of soluble long-chain sulfur intermediates still remains a limitation in NaSBs, leading to rapid capacity loss arising from the dissolution of active sulfur into the electrolyte. This problem is effectively circumvented in quasi-solid-state conversion cathodes by elimination of the presence of these soluble intermediates altogether, with only insoluble intermediates formed in the process. Herein, we discuss various cathode materials that undergo quasi-solid-state conversion when cycled in a liquid electrolyte, including chemically bonded short-chain sulfur species, shortchain sulfur via physical confinement, and quasi-solid-state conversion cathodes with long-chain sulfur moieties. We conclude by highlighting the current challenges and possible strategies to improve the mechanistic understanding and cycling performance of NaSBs for practical applications.

The increased demand for energy has prompted users to seek alternative energy storage devices. Post‐Li‐ion battery chemistries have been considered potential contenders for the development of next‐generation battery technologies. The high specific capacity (≈1675 mAh g−1) and high natural abundance (≈953 ppm) of sulfur provide opportunities to meet the rigorous requirements of the market's demands, such as high energy density and low cost. When combined with a high capacity metal anode (e.g., Na ≈ 1165 mAh g−1, Mg ≈ 2205 mAh g−1, and Al ≈2980 mAh g−1), it leads to high energy density that can outperform the existing battery technologies, including high‐energy Li‐ion batteries. Despite the unique attributes of the sulfur‐based battery system, it remains in infancy owing to the complex reaction chemistry of sulfur cathode, and the level of complexity increases with an increase in valency of metal ions. This review summarizes the unique aspects of a sulfur cathode essential to stabilizing sulfur cathode‐based high‐energy rechargeable batteries. Furthermore, deeper insight into the electrochemical performance of various metal–sulfur‐based systems has been provided. This review may pave the path for the researchers to accelerate the development of sulfur cathode for post‐Li‐ion batteries.
