Summary: The article introduces the application of LiBOB in lithium ion batteries, which can form a dense boron-containing polymer as a solid electrolyte interlayer to isolate the electrode material from the electrolyte and avoid side reactions. LiBOB can also act as an HF scavenger to maintain the structural integrity of electrodes and react with LiPF6 to generate LiDFOB as a clean-up agent for reactive oxygen radicals. The article summarizes the application and working mechanisms of LiBOB in high capacity and high voltage cathode materials, as well as the current challenges and strategies to overcome them. It provides useful insights for stable operation of high capacity LIBs under high voltage.

Summary: This study investigates the use of lithium difluoro(oxalate)borate (LiDFOB) as an electrolyte additive to overcome capacity fading in LiCoO2/graphite lithium-ion batteries at high voltages. The addition of 1 wt.% LiDFOB improves the battery's capacity retention after 300 cycles at a voltage range of 3.0-4.5 V from 42.1% to 80.2%. By coordinating with Co ions, LiDFOB inhibits cobalt dissolution from LiCoO2 and prevents cobalt deposition on the anode. Additionally, LiDFOB forms stable, uniform, and thin surface films on both positive and negative electrodes, inhibiting electrolyte decomposition and enhancing battery performance.

Summary: In this work, localized high concentration electrolytes (LHCEs) based on tetramethylene sulfone (TMS) were designed. TMS-based LHCEs can achieve excellent compatibility with high energy density lithium-ion batteries (LIBs) when combined with a proper additive. The unique solvation structure of LHCEs facilitates the formation of highly effective solid electrolyte interphase (SEI) and suppresses the degradation of positive electrode materials in LIBs. The superior interphasial properties of LHCEs are the key to realizing the long lifespan of high energy density LIBs.

Summary: This study presents the use of TMSPi and LiDFOB as film-forming additives in a conventional LiPF6-containing carbonate-based electrolyte solution to suppress the degradation of high-voltage lithium-ion battery electrolytes. TMSPi oxidizes on the LNMO cathode surface to form a stable cathode electrolyte interphase (CEI) layer, while LiDFOB has the potential to form a solid electrolyte interphase (SEI) on the graphite anode surface. The combination of these two additives effectively inhibits electrolyte degradation and improves capacity retention of high-voltage LIBs.

Summary: The design of a solid electrolyte interphase (SEI) plays a crucial role in improving the electrochemical performance of anode materials. In this study, lithium difluoro(oxalate)borate (LiDFOB) is used as an electrolyte additive to form a protective SEI film on Li3VO4 (LVO) anodes. The addition of LiDFOB results in a dense, uniform, stable, and LiF-richer SEI, which enhances the Li-ion storage kinetics. The generated SEI also prevents further decomposition of the electrolyte and maintains the morphology of LVO anodes during charge/discharge processes. This work demonstrates the effectiveness of LiDFOB as a multi-functional additive for LiPF6 electrolytes and provides insights into SEI construction for high-performance LVO anodes.

Summary: In this study, a dual-functional electrolyte additive, lithium tetrafluoro(fluoromalonato)phosphate (LFMP), was synthesized to improve the thermal stability of LiNi0.8Co0.1Mn0.1O2 (NCM811) cathode and graphite anode materials. LFMP additive showed excellent cyclability, storage performance, and mitigated gas evolution compared to its boron analog, lithium difluoro(fluoromalonato)borate (LFMB). The advantages of LFMP can be attributed to the superior cathode electrolyte interphase (CEI) and solid electrolyte interphase (SEI) layers derived from LFMP, which exhibit strong binding with O-2(center dot-) and weak binding with PF5, and favorable LiF formation.

Summary: The study confirms that the electrochemical performance of LNMO cathode with high voltage plateau can be significantly improved at low and high temperatures by adding lithium difluorophosphate (LiDFP) and dimethyl sulfite (DMS) as electrolyte additives. The enhanced performance is mainly attributed to the priority oxidation decomposition of LiDFP and the increased ionic conductivity of DMS-containing electrolytes at low temperature.
