Molecular Electrolyte Design Enables Sodium Batteries with LIBs-parity Energy-Density and Improved Sustainability

The research landscape of metal (Li, Na, K) batteries has long been hindered by a paradox between ether and carbonate solvents, which hampers their development. This motivates us to explore new electrolyte chemistries that reconcile the conflicting requirements without sacrificing sustainability.

Salt-In-Presalt Electrolyte Design for High-energy Sodium Batteries

Our present work introduces a new electrolyte design named “Salt-In-Presalt” (SIPS). This strategy maximizes the fluorinated anion functions at a low salt concentration and promotes inorganic electrolyte-electrode interphases to realize long-cycle performance for high-energy sodium batteries.

The asymmetric solvating design: a versatile electrolyte design strategy for micro-sized alloying anodes

Our work presents asymmetric electrolyte design, ie, the use of asymmetric solvating and lithium hexafluorophosphate salt to promote LiF interphase formation on micro-sized alloying anodes (Si, Al, Sn, Bi), achieving superior cycle performance for high-energy batteries using low-cost materials.
