“…In recent years, multifunctional additives have been increasingly more popular. These CEIforming additives typically contain functional groups such as isocyanate (NCO), [97][98][99][100] silane derivatives (SiO), [101][102][103][104][105][106] sultones (SO), [88,[107][108][109][110][111] borates (BO), [112][113][114][115] or phosphorouscontaining groups, [116][117][118][119][120] which are capable of scavenging HF. Many of these CEI-forming additives can also promote SEI formation on the anode, serving multiple important functions in the cell.…”

Lithium‐ion batteries (LIBs) are promising candidates within the context of the development of novel battery concepts with high energy densities. Batteries with high operating potentials or high voltage (HV) LIBs (>4.2 V vs Li+/Li) can provide high energy densities and are therefore attractive in high‐performance LIBs. However, a variety of challenges (including solid electrolyte interface (SEI), lithium plating, etc.) and related safety issues (such as gas formation or thermal runaway effects) must be solved for the practical, widespread application of HV‐LIBs. Most of these challenges arise in the region between the electrodes: the electrolyte region. This review provides an overview of recent development and progress on the electrolyte region, including liquid electrolytes, ionic liquids, gel polymer electrolytes, separators, and solid electrolytes for HV‐LIBs applications. A focus on improving the safety of these systems, with some perspectives on their relative cost and environmental impact, is given. Overall, the new information is encouraging for the development of HV‐LIBs, and this review serves as a guide for potential strategies to improve their safety, allowing the development of HV‐LIBs, including solid‐state batteries, to be accelerated to practical relevance.

Electrolyte additives have been explored to attain significant breakthroughs in the long-term cycling performance of lithium-ion batteries (LIBs) without sacrificing energy density; this has been achieved through the development of stable electrode interfacial structures and the elimination of reactive substances. Here we highlight the potential and the challenges raised by studies on electrolyte additives toward addressing the interfacially induced deterioration of high-capacity electrodes with a focus on Ni-rich layered oxides and Si, which are expected to satisfy the growing demands for high-energy-density batteries. We also discuss issues with the design of electrolyte additives for practical viability. A deep understanding of the roles of existing electrolyte additives depending on their functional groups will aid in the design of functional additive moieties capable of building robust interfacial layers, scavenging undesired reactive species, and suppressing the gas generation that causes safety hazards and shortened lifetimes of LIBs.

In this work, various electrolyte additives designed for enhanced performance at high voltages were evaluated with elevated temperature potentiostatic holds with LiNi 0.5 Co 0.2 Mn 0.3 /Li 4 Ti 5 O 12 full cells to determine their effect on the high voltage stability. Of the additives investigated, many showed increased oxidation current through the 60 hour potentiostatic holds test, and adversely affected both the capacity retention and interfacial impedance. Improved high voltage performance was observed with two additives, vinylene carbonate (VC) and 1,1,2,2-tetrafluoroethyl-2,2,3,3-tetrafluoropropyl ether (TTE), which was attributed to two different mechanisms of improvement. This work investigates some conclusions in the available literature of an additive molecule that decomposes on the charged cathode surface and passivates the surface against electrolyte oxidation. With the goal of increasing battery energy density for transportation applications, layered transition metal oxides cathodes of the form LiMO 2 (M = Ni, Co, Mn) have received significant attention.1-7 While these cathode materials have a high theoretical gravimetric capacity of ∼280 mAh/g, 8 achieving the high capacity of these materials requires very high charging voltages (>4.5V vs. Li + /Li), 2-4 above the stability range of conventional carbonate electrolytes.9,10 Enabling the additional high voltage capacity of the cathode materials requires new electrolytes that provide additional stability at high voltages at the charged cathode surface.The approach to creating compatible electrolytes has mainly fallen along two separate paths: either increasing the intrinsic anodic stability of the electrolyte, [11][12][13][14][15][16][17] or using a sacrificial component in small amounts (an additive) to "passivate" the cathode surface and inhibit continual electrolyte oxidation.18 20,32 have shown evidence of decomposition on various high voltage cathode surfaces through a variety of surface characterization techniques, including attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR) and X-ray photoelectron spectroscopy (XPS).However, this cathode "passivation" is conventionally inferred through a combination of experimental results, such as increased capacity retention, voltammetric methods indicating a lower anodic stability attributed to additive oxidation, changes to the XPS and/or FTIR spectra of the cathode that include components of the additive, and decreased impedance after cycling. While the results provided by the previously mentioned characterization methods can be reconciled with the conclusion that cathode "passivation" led to the improvement, this mechanistic process can be more accurately evaluated by monitoring the electrolyte oxidation current at a charged cathode surface through potentiostatic holds. A passivation layer will limit electron transfer from the electrolyte to the charged cathode surface. By this definition, this layer must have both a minimal electron conductivity as well as a minimal diffusio...
