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: Research on lithium metal is focused on achieving highly reversible lithium electrodeposition/dissolution for long cycle life. The extent of self-discharge can be controlled by increasing plated lithium capacity, tuning electrolyte chemistry, incorporating rest periods, or introducing lithiophilic materials. The dominant self-discharge mechanism is shown to be a morphological process rather than an irreversible chemical process.

Summary: SiOx has potential as an anode material for high energy density lithium-ion batteries due to its high specific capacity, but its long-term durability and storage performance are compromised by continuous solid-electrolyte-interphase (SEI) growth. In this study, we propose an optimal SEI with unique morphology and chemical composition, which facilitates the transport of Li ions during cycling. By adding nanodiamond (ND) and octadecylamine (ODA) additives, we successfully construct nanoscale pillar structure and inorganic Li-N and LiF-rich SEI on the Ti-SiOx@C electrode, resulting in a superior capacity retention of 91.0% at 1C after 500 cycles.

Summary: The construction of a stable cathode electrolyte interphase (CEI) is crucial for improving the NCM811 particle structure and interfacial stability through electrolyte engineering. In He's research, lithium hexamethyldisilazide (LiHMDS) is proposed as an electrolyte additive to facilitate the formation of a stable CEI on the NCM811 cathode surface while eliminating H2O and HF in the electrolyte. This approach enhances the cycling performance of the Li||NCM811 battery to 1000 or 500 cycles with a 4.5 V cut-off voltage at 25 or 60 degrees C.

Summary: This paper proposes a grey box model for fuel consumption prediction of wing-diesel hybrid vessels based on feature construction. By using both parallel and series grey box modeling methods and six machine learning algorithms, twelve combinations of prediction models are established. A feature construction method based on the aerodynamic performance of the wing and the energy relationship of the hybrid system is introduced. The best combination is obtained by considering the root mean square error, and it shows improved accuracy compared to the white box model. The proposed grey box model can accurately predict the daily fuel consumption of wing-diesel hybrid vessels, contributing to operational optimization and the greenization and decarbonization of the shipping industry.
