BASF investigating sodium-air batteries as alternative to Li-air; patent application filed with USPTO

Green Car Congress

In a paper in Nature Materials , a team of researchers from BASF SE and Justus-Liebig-Universität Gießen report on the performance of a sodium-air (sodium superoxide) cell. Their work, they suggest, demonstrates that substitution of lithium by sodium may offer an unexpected route towards rechargeable metal–air batteries.

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 long-duration, extended capacity Na-Al battery design for grid storage

Green Car Congress

Researchers led by the Department of Energy’s Pacific Northwest National Laboratory (PNNL) have extended the capacity and duration of sodium-aluminum batteries. The new sodium-based molten salt battery uses two distinct reactions. It is a variation of a sodium-metal halide battery. of peak charge capacity.

Researchers improve the performance of sodium-ion batteries by using tailored carbon anodes with hierarchical porosity

Green Car Congress

Researchers at Justus Liebig University, Giessen, Germany, have improved the performance of sodium-ion batteries ( earlier post ) by using tailor-made carbon materials with hierarchical porosity for the anode instead of common carbon-based anode materials. 1 at C/5 while exhibiting excellent rate capability and reasonable cycle life.

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.

Faradion demonstrates proof-of-concept sodium-ion electric bike

Green Car Congress

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.)

Antimony/carbon nanocomposite anode for Na-ion battery shows high capacity and stability

Green Car Congress

Researchers at Wuhan University (China) have synthesized a Sb/C (antimony/carbon) nanocomposite for use as an anode material in a room-temperature sodium-ion (Na-ion) battery. A comparison of the cycling capacities of the metallic Sb and the Sb/C nanocomposite electrode at a current rate of 100 mA/g. Source: Yang et al.
