Tin (Sn) shows promise as a robust electrode material for rechargeable sodium-ion (Na-ion) batteries, according to a new study by a team from the University of Pittsburgh and Sandia National Laboratory. Rechargeable Na-ion batteries work on the same basic principle as Li-ion batteries—i.e., for the positive electrode.
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. V vs Li/Li + ) with comparable capacities to the dominant graphite anodes.
RECLAIM: Electrochemical Lithium and Nickel Extraction with Concurrent Carbon Dioxide Mineralization ($2,999,997). Feedstocks will include Li/Ni/Ca/Mg-rich igneous and sedimentary minerals. Olivine is a CO 2 -reactive waste product that can be returned as tailings after capture carbon from the air. Harvard University.
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
This includes research on appropriate anodes, cathodes, and electrolytes for magnesium (Mg)-, sodium (Na)-, and lithium (Li)-based batteries and novel transition metal oxide- and nitride-based supercapacitor electrode materials. Magnesium is much more abundant in the Earth’s crust, making it less expensive than Li by a factor of 24.
Researchers from Nanyang Technical University (NTU) in Singapore have shown high-capacity, high-rate, and durable lithium- and sodium-ion battery (LIB and NIB) performance using single-crystalline long-range-ordered bilayered VO 2 nanoarray electrodes. This is important in boosting the high-rate performance in both Li and Na ion storage.
Designer of the first handheld analyzer that performs general alloy analysis and carbon in steels and stainless, SciAps remains the market leader with thousands of these devices in use daily for alloy and weld chemistry validation in the energy sector. SciAps recognizes that no single tool solves every problem. Don’t need REE performance?
Substantial progress in battery technology is essential if we are to succeed in an energy transition towards a more carbon-neutral society. Under such a scenario, the production of Li-ion batteries should expand hugely over the years to come, hence reviving the issue of finite Li reserves. —Grey and Tarascon.
