A team led by researchers from the Karlsruhe Institute of Technology (KIT) in Germany is proposing a new class of high entropy materials for energystorage applications. The Li-containing entropy-stabilized oxyfluoride (Li x (Co 0.2 V vs. Li + /Li, enabling its use as a cathode active material.
A team of researchers at the US Department of Energy’s Argonne National Laboratory has synthesized amorphous titanium dioxide nanotube (TiO 2 NT) electrodes directly grown on current collectors without binders and additives to use as an anode for sodium-ion batteries. —Xiong et al.
The US Department of Energy’s National Energy Technology Laboratory (NETL) is conducting research on alternative options to reduce costs and make large-scale energystorage safer and more practical. Innovative fabrication methods can also lead to significant energystorage system improvements.
Out of several candidates that could replace Li in rechargeable batteries, calcium (Ca) stands out as a promising metal. Not only is Ca 10,000 times more abundant than Li, but it can also yield—in theory—similar battery performance. —Prof. Haesun Park, Chung-Ang University, co-corresponding author. 202101698.
British battery R&D company Faradion has demonstrated a proof-of-concept electric bike powered by sodium-ion batteries at the headquarters of Williams Advanced Engineering, which collaborated in the development of the bike. Sodium-ion intercalation batteries—i.e., Oxford University was also a partner. Earlier post.)
Cycling performance of Li/SeS 2 ?C, Researchers at Argonne National Laboratory have developed selenium and selenium–sulfur (Se x S y )-based cathode materials for a new class of room-temperature lithium and sodium batteries. Unlike the widely studied Li/S system, both Se and Se x S y can be cycled to high voltages (up to 4.6
With the worldwide emphasis on renewable energy sources such as solar and wind, energystorage has become an essential solution for grid stability and reliability. Not only that, but energystorage is also an important research direction in the field of electric vehicles. Classification of energystorage.
In a review paper in the journal Nature Materials , Jean-Marie Tarascon (Professor at College de France and Director of RS2E, French Network on Electrochemical EnergyStorage) and Clare Gray (Professor at the University of Cambridge), call for integrating the sustainability of battery materials into the R&D efforts to improve rechargeable batteries.
