Argonne researchers find cathode material synthesis a key reason for performance degradation of sodium-ion batteries

Green Car Congress

One of the more promising candidates for batteries beyond the current standard of lithium-ion materials is the sodium-ion (Na-ion) battery. Na-ion is particularly attractive because of the greater abundance and lower cost of sodium compared with lithium. In addition, when cycled at high voltage (4.5

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.

New organic cathode for high performance solid-state sodium-ion battery

Green Car Congress

Solid-state sodium-ion batteries are safer than conventional lithium-ion batteries, which pose a risk of fire and explosions, but their performance has been too weak to offset the safety advantages. Normally, a solid-state battery’s ability to store energy is halted when the resistive cathode?electrolyte

New liquid alloy electrode significantly lowers operating temperature of sodium-beta batteries; improved performance

Green Car Congress

Researchers at Pacific Northwest National Laboratory (PNNL) have devised an alloying strategy that enables sodium-beta batteries to operate at significantly lower temperatures. The new electrode enables sodium-beta batteries to last longer, helps streamline their manufacturing process and reduces the risk of accidental fire.

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.

PG&E, Calif. Energy Commission launch 4MW sodium-sulfur grid storage pilot in San Jose

Green Car Congress

Pacific Gas and Electric Company (PG&E) and the California Energy Commission today unveiled a utility-scale sodium-sulfur battery energy storage system ( earlier post ) pilot project to better balance power needs of the electric grid. The system has a 4 megawatt capacity, and can store more than six hours of energy.
