Abstract: Water‐in‐salt electrolytes have been widely explored because of their expanded electrochemical stability ( .0 V). However, the instability of solid‐electrolyte interphase (SEI) in aqueous electrolytes leads to their reductive decomposition on the negative electrodes of low‐potential anode materials. Here, we demonstrate significant improvement in the cycle performance of a Li 4 Ti 5 O 12 electrode using a Li−Ca binary salt hydrate (LCH) electrolyte in combination with an optimized electrochemical pretreatment process. Compared with a hydrate‐melt electrolyte, the LCH electrolyte provided less water‐soluble Ca‐based SEI components, and careful pretreatment process enabled the formation of a thicker SEI layer on the Li 4 Ti 5 O 12 electrode. Protected with the hardly soluble, thick SEI layer, the Li 4 Ti 5 O 12 electrode effectively mitigated unfavorable side reactions and achieved 95.5 % capacity retention over 50 cycles. These results offer insight into a promising route for stable SEI layer formation for the practical use of low‐potential anode materials in aqueous rechargeable lithium‐ion batteries.

Abstract: Since aqueous lithium‐ion batteries (LIBs) were first proposed, electrolyte design has been intensively studied. We report a simple anionic surfactant, i. e., a lithium dodecyl sulfate (LiDS)‐based aqueous electrolyte, capable of enhancing the Li ion transport properties in the bulk and protecting the electrode at the interface. The self‐assembly of DS anions into micelles effectively limited anion diffusion, enabling nearly single Li‐ion conduction in the bulk electrolyte. The interfacial adsorption of DS molecules formed a hydrophobic layer at the electrolyte/electrode interface under the electric field of the electric double layer, excluding water molecules from the interface. Consequently, the electrochemical window of the aqueous electrolyte was expanded to 3.0 V. This electrolyte improved the cycle performance and rate capability of the LiFePO 4 /LiTi 2 (PO 4 ) 3 full‐cell compared to a 1.0 mol dm −3 Li 2 SO 4 /H 2 O reference electrolyte. These results provide a new twist in the design of liquid electrolytes for aqueous LIBs.
