Chalmers team develops graphite-like anode for Na-ion batteries; Janus graphene

Green Car Congress

Researchers at Chalmers University of Technology, Sweden, have developed a nanometric graphite-like anode for sodium ion (Na + storage), formed by stacked graphene sheets functionalized only on one side, termed Janus graphene. The estimated sodium storage up to C 6.9 Na is comparable to graphite for standard lithium ion batteries.

French researchers develop sodium-ion battery in 18650 format; performance comparable to Li-ion

Green Car Congress

Researchers within the RS2E network on electrochemical energy storage (Réseau sur le stockage électrochimique de l’énergie) in France have developed the first sodium-ion battery in an 18650 format. The main advantage of the prototype is that it relies on sodium, an element far more abundant and less costly than lithium.

Researchers demonstrate concept desalination battery

Green Car Congress

A team from Stanford University and Ruhr-Universität Bochum have demonstrated the novel concept of a “desalination battery” that uses an electrical energy input to extract sodium and chloride ions from seawater and to generate fresh water.

Univ. of Texas researchers propose lithium- or sodium-water batteries as next generation of high-capacity battery technology; applicable for EVs and grid storage

Green Car Congress

John Goodenough, are proposing a strategy for high-capacity next-generation alkali (lithium or sodium)-ion batteries using water-soluble redox couples as the cathode. The present sodium-sulfur battery operates above 300 °C. A = lithium or sodium (Li or Na), M represents a metal and 1 ≤ n < z. Credit: ACS, Lu et al.

Researchers develop rechargeable hybrid-seawater fuel cell; highly energy density, stable cycling

Green Car Congress

The circulating seawater in the open-cathode system results in a continuous supply of sodium ions, endowing the system with superior cycling stability that allows the application of various alternative anodes to sodium metal by compensating for irreversible charge losses. an alloying material), in full sodium-ion configuration.

BASF announces winners of the open innovation contest on energy storage

Green Car Congress

The winning concepts were: A molten air battery that uses a molten salt electrolyte at elevated temperature from Professor Stuart Licht at George Washington University. Sustainable technologies should make it possible to store power from the grid and feed power back into it.

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. Our concept has the following advantages: Compared to carbon dioxide, solid bicarbonates are easy to handle and highly soluble in aqueous media (96 g L -1 NaHCO 3.
