Zn-ion batteries (ZIBs) have garnered significant attention due to their environmental friendliness and low cost. However, severe dendritic Zn growth, surface corrosion, and H2 evolution reactions, have limited their further application. In this work, we construct a dilute and non-flammable electrolyte composed of 0.5 M Zn(BF4)2 salts in a cosolvent of tetrahydrofuran (THF)/triethyl phosphate (TEP)

Accurate parameter identification of simplified electrochemical models for lithium-ion batteries (LIBs) is crucial for battery management and control. However, existing methods often struggle with parameter coupling, computational efficiency, and physical consistency. This paper presents a non-destructive and rapid parameter identification methodology through an integration of multi-step (MS) and physical-informed

Lithium-ion batteries are the core energy storage unit of electric vehicles and energy storage power stations, but their thermal safety is still the great challenge.

As renewable energy penetration increases, thermochemical energy storage (TCES) has gained attention for its high energy density and potential for long-duration applications.

This lack of a comprehensive

High-entropy materials (HEMs) have emerged as promising oxygen electrocatalysts due to their compositional flexibility, tunable electronic structures, entropy-stabilized phases, and highly adjustable catalytic properties.
