Rechargeable metal-air batteries are considered a promising energy storage solution owing to their high theoretical energy density. The major obstacles to realising this technology include the slow kinetics of oxygen reduction and evolution on the cathode (air electrode) upon battery discharging and charging, respectively. Here, we report non-precious metal oxide catalysts based on spinel-type ...

Lithium–Sulfur Batteries In article number 2204353, Jeongyeon Lee, Ho Seok Park, and co-workers design triethylene glycol functionalized polymeric cobalt phthalocyanines uniformly coated onto multi-wall carbon nanotubes, which act as an efficient redox mediator in lithium–sulfur batteries. The as-designed materials enable co-operative catalytic lithiophilic sites, facilitating the conversion re...

The bottleneck of recycling chains for spent lithium-ion batteries (LIBs) is the recovery valuable metals from black matter that remains after dismantling and deactivation in pre‑treatment processes, which has to be treated a subsequent step with pyrometallurgical and/or hydrometallurgical methods. In course this paper, investigations heating microscope were conducted determine high-temperature...

Rechargeable lithium–oxygen (Li-O2) batteries have recently attracted great attention because they can theoretically store 5–10 times more energy than current lithium-ion batteries, which is essential for clean energy storage, electric vehicles, and other high-energy applications. However, to use Li-O2 batteries for practical applications, numerous scientific and technical challenges need to be...

New and improved materials for energy storage are urgently required to make more efficient use of our finite supply of fossil fuels, and to enable the effective use of renewable energy sources. Lithium ion batteries (LIB) are a key resource for mobile energy, and one of the most promising solutions for environment-friendly transportation such as plug-in hybrid electric vehicles (PHEVs). Among t...

The review records, categorises and assesses the environmental impacts, sources pollution pathways of spent lithium-ion batteries.

Silicon is receiving discernable attention as an active material for next generation lithium-ion battery anodes because of its unparalleled gravimetric capacity. However, the large volume change of silicon over charge-discharge cycles weakens its competitiveness in the volumetric energy density and cycle life. Here we report direct graphene growth over silicon nanoparticles without silicon carb...

Electrochemical capacitors and lithium-ion batteries have seen little change in their electrolyte chemistry since their commercialization, which has limited improvements in device performance. Combining superior physical and chemical properties and a high dielectric-fluidity factor, the use of electrolytes based on solvent systems that exclusively use components that are typically gaseous under...

Large-scale high-energy batteries with electrode materials made from the Earth-abundant elements are needed to achieve sustainable energy development. On the basis of material abundance, rechargeable sodium batteries with iron- and manganese-based positive electrode materials are the ideal candidates for large-scale batteries. In this review, iron- and manganese-based electrode materials, oxide...
