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

Green Car Congress

For the proof-of-concept, the cells were manufactured to be larger than necessary to avoid unnecessary costs and lengthy manufacturing processes at this early stage. Sodium-ion intercalation batteries—i.e., Thus, insertion/deinsertion of sodium ions in a host material is much more difficult than that of lithium ions.

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.

OSU team demonstrates concept of potassium-air battery as alternative to lithium-air systems

Green Car Congress

Researchers at Ohio State University (OSU) have demonstrated the concept of a potassium-air (K?O Recently, researchers have also found out the instability of electrolyte and carbon electrode under the high charging potential (>3.5 V), which contributes to the low rechargeability.

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. The electrodes are then recharged in this solution, releasing ions and creating brine.

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

Example of a lithium-water rechargeable battery. Researchers at the University of Texas, including Dr. 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.

CO2-neutral hydrogen storage with a bicarbonate/formate system

Green Car Congress

Researchers at the Leibnitz Institute for Catalysis (Rostock, Germany) have introduced a new approach to hydrogen storage that is based on simple salts of formic acid and carbonic acid. A fundamental problem with the use of these storage materials is the separation of the carbon dioxide formed when the hydrogen is released.

Ningbo researchers propose mixed-ion Li/Na batteries

Green Car Congress

Lithium-intercalation compounds and sodium-intercalation compounds are used for anode and cathode, respectively. Sodium-ion based rechargeable batteries (SIBs, e.g., earlier post ) are of interest due to sodium’s abundance, far lower prices, and a greener synthesis while maintaining a similarity in ion-insertion chemistry.
