Researchers have identified oxygen trapping in high-sodium cathodes as the main cause of voltage decay. Using EPR spectroscopy, the team uncovered structural changes and trapped O2 accumulation, providing guidance for designing more stable sodium-ion batteries for electric vehicles and energy storage.
