However, these cathode materials cause problems such as harmful parasitic reactions at the cathode/electrolyte interface, degradation of the layered structure, and the creation of microcracks. Herein, a microstructural refinement and intergranular coating strategy is proposed to engineer ultrahigh nickel cathode LiNi<sub>0.96</sub>Co<sub>0.03</sub>Mn<sub>0.01</sub>O<sub>2</sub> (NCM). The W-doping-induced fine-grained microstructure not only endows NCM with excellent mechanical properties but also promotes infiltration of the fluoride-containing coating along the grain boundaries inside the secondary particles, thereby forming intergranular coatings. This combined fine-grained microstructure and intergranular coating strategy reduces the formation of microcracks and suppresses the additional parasitic electrolyte reactions caused by them, thereby inhibiting the degradation of the layered phase. Consequently, the modified NCM cathode achieved exceptional electrochemical properties, especially delivering a high initial capacity of 230.8 mA h g<sup>−1</sup> (0.1 C) and a capacity retention exceeding 96% after 100 cycles at 0.5 C in half cells. After 500 cycles in full cells, the capacity retention increases by 21.2% compared with NCM.

Here we employed triphenylphosphine (TPP) and triphenylphosphine oxide (TPPO) as the model passivators in p-MPSCs. TPPO has a more negatively charged center than TPP, which enables its stronger coordination with one of the most common and detrimental defects at the GBs—undercoordinated lead.

However, the underlying relationship between high-rate cycling and electrode degradation for LRMO, particularly concerning structural evolution, still remains unclear. Benefiting from the high time resolution abilities of liquid-metal-jet operando two-dimensional X-ray diffraction, it is observed that the Li<sub>2</sub>MnO<sub>3</sub> phase in LRMO is gradually activated accompanied by the emergence of oxygen vacancies during cycling at 1 C (1 C = 250 mA/g).

A comprehensive understanding of the low-temperature aging mechanisms throughout the whole life cycle of LIBs is crucial. However, existing research is limited, which typically focuses on capacity degradation to 80%. To fill this gap, this paper conducts low-temperature cyclic aging tests at three different charging rates. The investigation employs differential voltage analysis, the distribution of relaxation times technique, and disassembly characterization to explore both thermodynamic degradation and kinetic degradation, alongside a correlation analysis of the factors influencing these degradation processes. The results reveal two distinct knee points in the capacity decline of LIBs during the whole life cycle, in contrast to prior studies identifying only one. Before the first knee point, the thickening of the SEI film dominates capacity loss, with higher charging rates accelerating the process. After the first knee point, the main degradation mechanisms shift to lithium plating and the fracture of the positive electrode active particles. These two aging factors become more pronounced with ongoing cycling, culminating in a second knee point in capacity decline. Notably, a novel finding demonstrates that after the second knee point, capacity degradation progresses faster at lower charging rates compared to medium rates. The reason is the fracture of graphite particles also becomes a critical contributor to the severe capacity degradation at lower charging rates.
