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

New high energy, highly stable cathode for sodium-ion batteries

Green Car Congress

Researchers in South Korea have developed a novel high-energy cathode material, Na 1.5 F 0.7 , for sodium-ion (Na-ion) batteries (NIBs). This new material provides an energy density of 600 Wh kg –1 , the highest value among Na-ion cathodes. In a prior study, they developed a new Li-ion battery electrode—Li 1.1
