Hybrid electrolyte enables solid-state sodium batteries sustaining 50,000 cycles

Solid-state sodium (Na) batteries open the opportunity for more sustainable energy storage due to their safety, low cost and high energy density. Inorganic solid electrolytes show notable advantages for such technologies but suffer from poor interfacial compatibility, rendering hybrid solid–liquid electrolytes an alternative. Here we show that the interfacial failure in the hybrid electrolyte system (Na3Zr2Si2PO12 (NZSP) and 1 M NaClO4 in propyl…

Anion Strategy Boosts Ether Electrolytes for Na-Ion Batteries

In the rapidly evolving landscape of energy storage, the quest for more efficient, safer, and cost-effective battery technologies has become a central scientific challenge. Among the burgeoning alternatives to lithium-ion batteries, sodium-ion batteries (SIBs) have gained considerable attention due to the natural abundance and low cost of sodium. However, a critical obstacle remains: developing electrolytes capable of withstanding high voltages …
