Summary: This study demonstrates the preparation of quasi-solid electrolytes (QSEs) and proves that QSEs can promote more uniform lithium deposition and the formation of a stable solid electrolyte interface (SEI), leading to increased safety and stability of lithium batteries. QSEs also exhibit superior liquid retention and a polymer that inhibits the shrinkage of the separator, reducing internal heat reaction and the occurrence of large-scale internal short circuits. Therefore, QSEs provide more stable battery performance and reduce severe destruction caused by thermal runaway.

Summary: Cyclic aging of lithium-ion batteries leads to capacity decline, impedance increase, and polarization deepening. A study was conducted on commercial 18650 lithium-ion batteries using fast charge/discharge cycles to determine the influence of cyclic aging on safety performance. The results showed a nonlinear three-stage change in aging, with higher charge/discharge rates exacerbating the aging state. Thermal abuse tests revealed that aged cells have better thermal stability but a higher risk of thermal runaway, possibly due to flammable gas and exothermic reactions during fast charge/discharge processes. This study highlights the potential for aged cells in products like electric vehicles to trigger thermal runaway.

Summary: Secondary zinc-air batteries (ZABs) show potential as sustainable energy storage, but their current capability is unsatisfactory. The limitations are mainly due to the air electrodes, hindering practical applications and commercialization. This study explores the use of metallic nickel as a conductive additive in the air electrodes, compared to carbon nanotubes (CNT), and demonstrates that the density and interaction of the additive with the active material are crucial for achieving long cycle life. The use of Ni as a conductive agent significantly increased the cycle life of secondary ZABs, delivering more than 2,400 cycles compared to only 88 cycles for carbon-based batteries.

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.
