“…Researchers have also reported that PTSI as a less investigated additive can generate better SEIs with less inorganic components in which due to the presence of S=O groups, PF 5 can be suppressed as delocalized N cores can act as weak base sites [112]. And more recently, 3-sulfolene (3SF) as a film-forming agent was used to reduce electrolyte reduction [221]. Additives that stabilize SEI can be divided into two subgroups including SEI formers and SEI modifiers [222] and phenyl carbonate, regarded as a "modifier" additive, can outperform VC by maintaining low impedance and gas production in NMC111/graphite pouch cells and therefore can be used to stabilize cells [222].…”

The demand for lithium-ion batteries (LIBs) with high mass-specific capacities, high rate capabilities and long-term cyclabilities is driving the research and development of LIBs with nickel-rich NMC (LiNi x Mn y Co 1−x−y O 2 , x ⩾ 0.5 ) cathodes and graphite (Li x C 6 ) anodes. Based on this, this review will summarize recently reported and widely recognized studies of the degradation mechanisms of Ni-rich NMC cathodes and graphite anodes. And with a broad collection of proposed mechanisms on both atomic and micrometer scales, this review can supplement previous degradation studies of Ni-rich NMC batteries. In addition, this review will categorize advanced mitigation strategies for both electrodes based on different modifications in which Ni-rich NMC cathode improvement strategies involve dopants, gradient layers, surface coatings, carbon matrixes and advanced synthesis methods, whereas graphite anode improvement strategies involve surface coatings, charge/discharge protocols and electrolyte volume estimations. Electrolyte components that can facilitate the stabilization of anodic solid electrolyte interfaces are also reviewed, and trade-offs between modification techniques as well as controversies are discussed for a deeper understanding of the mitigation strategies of Ni-rich NMC/graphite LIBs. Furthermore, this review will present various physical and electrochemical diagnostic tools that are vital in the elucidation of degradation mechanisms during operation to supplement future degradation studies. Finally, this review will summarize current research focuses and propose future research directions.

“…[94,95] Sulfur-based additives (e.g., 1,3,2-dioxathiolane-2,2-dioxide (DTD) and its derivatives) with smaller lowest unoccupied molecular orbital (LUMO) than that of PC can be reduced above the PC cointercalation potential, forming a Li 2 SO 3 and ROSO 2 Li-rich protective film. [96][97][98][99][100][101] Allyl sulfide (AS)-added electrolytes were demonstrated to be spontaneously decomposed on the surface of soaked graphite and form a sulfur-containing inner layer SEI, which facilitated the charge-transfer process at low temperatures. [102] Besides, the addition of 2 wt% AS could also suppress Li plating, further enhancing the low-temperature performance of cells.…”

With the highest energy density ever among all sorts of commercialized rechargeable batteries, Li‐ion batteries (LIBs) have stimulated an upsurge utilization in 3C devices, electric vehicles, and stationary energy‐storage systems. However, a high performance of commercial LIBs based on ethylene carbonate electrolytes and graphite anodes can only be achieved at above −20 °C, which restricts their applications in harsh environments. Here, a comprehensive research progress and in‐depth understanding of the critical factors leading to the poor low‐temperature performance of LIBs is provided; the distinctive challenges on the anodes, electrolytes, cathodes, and electrolyte–electrodes interphases are sorted out, with a special focus on Li‐ion transport mechanism therein. Finally, promising strategies and solutions for improving low‐temperature performance are highlighted to maximize the working‐temperature range of the next‐generation high‐energy Li‐ion/metal batteries.
