The article “Aqueous/Non-aqueous Hybrid Electrolyte for Sodium-ion Batteries” is among the most read articles for the past month on the website of the journal ACS Energy Letters.

 

The team of researchers directed by Stefano Passerini reported an aqueous/nonaqueous hybrid electrolyte based on sodium trifluoromethanesulfonate with an expanded electrochemical window up to 2.8 V and high conductivity (∼25 mS cm–1 at 20 °C). The hybrid electrolyte inherited the safety characteristic of aqueous electrolytes and the electrochemical stability of nonaqueous systems, enabling stable and reversible operation of the Na3V2(PO4)3/NaTi2(PO4)3 sodium-ion battery.
