Stanford team develops sodium-ion battery with performance equivalent to Li-ion, but at much lower cost

Green Car Congress

Stanford researchers have developed a sodium-ion battery (SIB) that can store the same amount of energy as a state-of-the-art lithium ion, at substantially lower cost. Thus, further research is required to find better sodium host materials. The sodium salt makes up the cathode; the anode is made up of phosphorous.

UNSW team demonstrates high reversible hydrogen storage capacity under mild conditions for sodium borohydride using novel core-shell nanostructure; potential for vehicles

Green Car Congress

A team from the University of New South Wales (Australia) reports on a novel core-shell strategy leading to high and stable hydrogen absorption/desorption cycling for sodium borohydride (NaBH 4 ) under mild pressure conditions (4 MPa) in an open-access paper in the journal ACS Nano. With a high storage capacity (10.8

New solid hydrogen-on-demand fuel cell from HES Energy Systems flies UAV for record 6 hours

Green Car Congress

The Skyblade 360 fuel cell system developed by HES and DSO is extremely lightweight in comparison to lithium batteries that typically power this aircraft, and it is also extremely compact: its 1L fuel cartridge holds 1000 Wh of usable energy. It took HES several years to achieve this performance.

Antimony nanocrystals as high-capacity anode materials for both Li-ion and Na-ion batteries

Green Car Congress

The data for 10 nm Sn (tin) NCs are shown for comparison. Initial studies revealed that antimony could be suitable for both rechargeable lithium- and sodium-ion batteries because it is able to store both kinds of ions. 20C (1C = 0.66 1 , 9 cycles at each C-rate, first cycle at 0.1C).

CO2-neutral hydrogen storage with a bicarbonate/formate system

Green Car Congress

Metal hydride tanks store hydrogen in a relatively manageable volume but are very heavy and expensive, as well as operating only at high temperatures or far too slowly. The nontoxic aqueous solution of formate is easily stored and transported. to sodium formate in 96% yield at 70 °C in water/THF without additional CO 2.

UNSW team proposes hard carbons from automotive shredder residue as anode material for sodium-ion batteries

Green Car Congress

Researchers from UNSW Sydney (Australia) report in an open-access paper in the Journal of Power Sources on the use of hard carbons derived from automotive shredder residue (ASR) as a suitable anode electroactive material for sodium-ion batteries (NIBs). The situation is much worse for graphite. Sarkar et al. 2023.233577

UW researchers discover major lithium resource in Wyoming; potential integrated brine production/CO2 storage system

Green Car Congress

By comparison, the lithium reserves at Silver Peak, Nev.—the Before CO 2 can be safely and successfully stored, these brines must first be removed from underground geologic formations to manage pressure in the reservoirs during CO 2 injection.
