Check out our latest work entitled “Insights into Electrolyte-Solvent Interactions and SEI Formation for Sustainable Sodium-Ion Battery Operation at Low Temperatures,” now published in . This work explored how tailoring electrolyte-solvent interactions enables sodium-ion batteries to operate at ultra-low temperatures, down to −110°C for the first time. Our study combines MD/DFT simulations with experimental NMR, Raman, and XPS analysis to reveal how optimized solvation structures and stable SEI layers improve performance in extreme environments.

This work is a significant step toward crucial insights, which offer promising directions for the future development of efficient, durable, and reliable SIBs for extreme conditions.

Insights into Electrolyte‐Solvent Interactions and SEI Formation for Sustainable Sodium‐Ion Battery Operation at Low Temperatures This article discusses a new electrolyte blend for the operation of sodium-ion batteries at very low temperatures. The importance of adjusting the electrolyte is thoroughly examined using theoretical...

Check out our latest work on Aluminum-ion batteries published in , entitled "Exploring FeSe2 and porous carbon composite as a cost-effective host for Al3+ in aqueous Aluminum ion batteries."
We developed the FeSe2-decorated porous N, S-doped carbon spheres (FSPNSCS) as a cathode material for aqueous aluminum-ion battery.
By combining FeSe2 with nitrogen and sulfur-doped carbon, we created a flexible and robust structure that addresses major challenges in aluminum-ion batteries, such as stability and long-term cycling.
This work is a significant step toward post–lithium-ion energy storage, helping move us closer to a more sustainable and resilient energy future.
