RAL proposes new efficient and low-cost process to crack ammonia for hydrogen using sodium amide; transportation applications

Green Car Congress

RAL researchers are proposing a new process for the decomposition of ammonia to release hydrogen that involves the stoichiometric decomposition and formation of sodium amide from Na metal. To date, very few candidates show potential beyond that of the seminal work on titanium-doped sodium alanate. Credit: ACS, David et al.

Fraunhofer researchers develop new low-cost dry-film electrode production process

Green Car Congress

BroadBit uses it to produce new types of sodium-ion batteries. First, they mix the active materials, intended later to release the stored energy, with additives to create a paste. On a laboratory scale, the IWS can already coat electrode foil with a remarkable production speed of several meters per minute. 2019.05.033.

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.

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.

Vanderbilt researchers find iron pyrite quantum dots boost performance of sodium-ion and Li-ion batteries

Green Car Congress

nm, average) of iron pyrite (FeS 2 ) nanoparticles are advantageous to sustain reversible conversion reactions in sodium ion and lithium ion batteries. In the paper, they reported reversible capacities of more than 500 and 600 mAh/g for sodium and lithium storage for ultrafine nanoparticles, along with improved cycling and rate capability.

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. V was developed.

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

Green Car Congress

Schematic illustration of the designed hybrid-seawater fuel cell and a schematic diagram at the charged–discharged state. Sodium can serve as an alternative to lithium in rechargeable batteries as the reversible storage mechanisms for sodium ions are very similar (e.g., an alloying material), in full sodium-ion configuration.
