US doubles high-voltage sodium battery life, cells hit 500 cycles

Researchers at the Pacific Northwest National Laboratory have developed a meta-weakly solvating electrolyte that allows for the stable operation of high-voltage sodium-ion batteries. “Developing alternative battery systems based on earth-abundant elements has thus become increasingly important,” said the researchers in a new study published in the journal Nano Energy. “Given that sodium is the closest alkali metal to lithium, sharing similar che…

New electrolyte tech enables stable operation of high-voltage sodium-ion batteries

U.S. researchers developed a meta-weakly solvating electrolyte that optimizes sodium-ion solvation structure, enabling faster ion transport, reduced side reactions, and improved interfacial stability in high-voltage sodium-ion batteries. This design significantly extends cycle life and outperforms conventional and localized high-concentration electrolytes by promoting more uniform and stable electrode–electrolyte interfaces.From ESS News Researc…
