Summary: In order to develop high-energy-density Li-metal batteries, the challenges faced by high-voltage/high-capacity cathodes and the longstanding problems with lithium-metal anodes need to be addressed. These challenges are primarily due to the instability at the interface between electrodes and electrolytes. This study introduces a strategy using concentrated nitrile electrolytes with co-additives to enhance the stability of the electrolyte. The results demonstrate that the improved electrolyte can work stably under high voltage and high temperature conditions, and exhibit good cycling performance.

It finds that uniform electrodeposition can be achieved when the applied current density is below the DLCD. Non-uniform electrodeposition leads to preferential deposition of Li metal within broken solid electrolyte interphases and increased consumption of active Li. Thus, lowering the current density or increasing the DLCD are proposed as strategies for uniform electrodeposition and stable interfaces of Li metal.

Summary: High-concentration water-in-salt (WIS) electrolytes expand the stable electrochemical window of aqueous electrolytes, enabling the development of high-voltage aqueous Li-ion batteries (ALIBs). However, the high lithium salt concentration of ALIBs leads to high cost and poor kinetic performance. It is challenging for ALIBs to find aqueous electrolytes with the right concentration to balance electrochemical window, kinetic performance, and cost. By introducing a small number of hydrophobic cations to a lower electrolyte concentration, ALIBs with these concentration-lowered electrolytes achieve a stable electrochemical window and improved kinetic performance.

Summary: Due to their potential use in portable applications such as electric vehicles, lithium-metal batteries (LMBs) have attracted attention for their low electrochemical potential and high theoretical specific energy. However, the uncontrolled growth of lithium dendrites during cycling has been a challenge. Recently, the concept of using localized high-concentration electrolytes (LHCEs), achieved by diluting high concentration electrolytes with inert solvents, has shown promise in enabling dendrite-free cycling of LMBs. In this study, the reactions of lithium bis(fluorosulfonyl)imide (LiFSI) in a mixture of dimethoxyethane (DME)/tris(2,2,2-trifluoroethyl) orthoformate (TFEO) electrolyte at a lithium metal anode were investigated. The formation mechanism of the solid electrolyte interface (SEI) was studied using a hybrid ab initio and reactive force field (HAIR) method. The results revealed important initial reduction reactions of LiFSI, TFEO, and DME, leading to the formation of a LiF-rich SEI inorganic inner layer (IIL) and unsaturated carbon products from TFEO. These findings can provide valuable insights for the future design of improved electrolytes.

Summary: The formation mechanisms of SEI in electrolytes with DEC and EC were studied, revealing that LEC can disperse in the electrolyte while LEDC cannot. First-principles calculations confirmed that the low polymerization degree of LEC leads to its good dispersity, while poly-LEDC can remain on the Li surface as the stable SEI.
