Solution-Processed MoS-Expanded Graphite as a Fast-Charging Anode for Lithium-Ion Batteries.

The widespread demand for battery-powered technologies has propelled the search for efficient and commercially viable electrode materials with fast-charging abilities. Reported herein is an MoS-expanded graphite (EG) composite as a stable and high-rate lithium-ion battery (LIB) anode, delivering specific capacities of 796 mAh g at 0.5 A g and 320 mAh g at 20 A g over 400 cycles.

Topochemically synthesized NbVS as a stable anode for sodium-ion batteries.

Ternary metal sulfides having layered morphology are considered as potential active materials for various applications. Herein, NbVS is synthesized topochemically for the first time using a Nb-V-HDA complex having a lamellar structure by employing HS gas as the sulfidation agent. NbVS, as an anode for SIBs, exhibited a specific capacity of 101.

Amorphous Anode Materials for Fast-charging Lithium-ion Batteries.

Fast-charging technology is set to revolutionize the field of lithium-ion batteries (LIBs), driving the creation of next-generation devices with the ability to get charged within a short span of time. From the anode perspective, it is of paramount importance to design materials that can withstand continuous Li insertion/deinsertion at high charging rates and still remain unaffected by factors such as mechanical fractures, electrolyte side reactions, polarisation, lithium plating and heat generation. Herein, the recent advancements in the design of amorphous materials as anodes for fast-charging LIBs have been discussed.

3R-NbS as a highly stable anode for sodium-ion batteries.

Anode materials for advanced sodium-ion batteries (SIBs) require major improvements with regard to their cycling stability, which is a crucial parameter for long-term battery operation. Herein, we report 3R-NbS, synthesised by a simple solid-state annealing route, as an anode for SIBs with remarkable cycling stability for 2500 cycles at 0.5 A g.

Impact of Glasgow Climate Pact and Updated Nationally Determined Contribution on Mercury Mitigation Abiding by the Minamata Convention in India.

India is one of the largest emitters of atmospheric anthropogenic mercury (Hg) and the third-largest emitter of greenhouse gases in the world. In the past decade, India has been committed to the Minamata Convention (2017) in addition to the Paris Climate Change Agreement (2015) and the Glasgow Pact (2021). More than 70% to 80% of India's mercury and carbon dioxide emissions occur because of anthropogenic activities from coal usage.
