Summary: With the proliferation of new electronic and optoelectronic devices worldwide, the development of more reliable power sources with better energy densities and longer lifespans has become necessary. Supercapacitors have emerged as excellent energy storage technologies due to their high power, quick charging and discharging, and prolonged cyclic stability. However, the extremely low energy density of existing supercapacitors significantly limits their wide range of applications. Asymmetric supercapacitors (ASCs) built with two different electrode materials offer a wide operational voltage window, which considerably improves energy density. This critical analysis explores the materials and fabrication advancements in ASCs over the past few decades, as well as the current challenges and prospects for the future.

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.
