•Solving the challenges of the cathode materials and solid-state electrolytes will accelerate the commercialization of lithium-sulfur batteries (LSBs)•Chemical adsorption is a promising method for ...efficient integration of sulfur onto porous carbon-based electrode materials, thereby mitigating the shuttle effect.•Metal-based nano-electrocatalysts should form an integral part of the cathode materials to drive the kinetics of the polysulfides.•Garnet-based oxide solid electrolytes provide the best stability against lithium metal and lithium polysulfides, making them the most promising candidates for LSBs.
Lithium-sulfur batteries (LSBs) have sparked a lot of attention due to their high theoretical energy density and cost-effectiveness. However, several challenges, notably unstable cycle life and low sulfur consumption, have hampered the development of workable LSBs for commercial use. Most of these challenges arise from the cathode materials and liquid electrolytes. This mini-review attempts to highlight the current advancements in cathode materials and solid-state electrolytes for the development of next-generation LSBs.
The increasing CO 2 concentration in the atmosphere has caused profound environmental issues such as global warming. The use of CO 2 as a feedstock to replace traditional fossil sources holds great ...promise to reduce CO 2 emissions. The electrochemical conversion of CO 2 has attracted much attention because it can be powered by renewable sources such as solar energy. In this review article, we provide insight into the important parameters when studying CO 2 RR and give a comprehensive review on the description of synthesis methods with electrocatalytic CO 2 reduction over bimetallic copper-based materials. Due to the important bibliographic data on Cu bimetallic materials, we have limited this review to Sn, In, Pd, Zn and Ag. At the end of this review, challenges and perspectives for further upgrading have been included to briefly highlight the important future considerations of this rapidly growing technology.

To expedite the development of lithium-sulfur (Li–S) battery technology, it is necessary to address the inherent technological hurdles surrounding sulfur-based cathodes, including mitigating the ...shuttle effect and enhancing the electrical conductivity of sulfur. The use of biomass-derived carbonaceous materials offers a promising avenue to alleviate these challenges and help reduce the carbon footprint associated with battery technologies. Herein, we report the green synthesis of carob-derived carbonaceous material without additional physical/chemical activation steps, making the process sustainable, affordable, and eco-friendly. The obtained carob-derived carbon (CC) offers a hierarchical micro/meso/macroporous structure with a high surface area of 633 m2 g−1. The electrochemical performance with a sulfur content of 70% (CC@S70) in the composite and a sulfur mass loading of 1 mg cm−2 delivers an initial discharge capacity of 1405 mAh g−1, reducing to 798 mAh g−1 after 260 cycles. Increasing the sulfur content to 90% in the cathode (CC@S90) yields a high capacity in Li–S cells, reaching a discharge capacity of 937 mAh g−1 with a sulfur loading of 2 mg cm−2 at 0.3C (1C = 1675 mA g−1) after 100 cycles. The improved performance can be attributed to the well-preserved interconnected pores within the carbon material, serving as an efficient framework to accommodate high sulfur content.
