Summary: The effect of applied potential on the crystallography, morphology, optical properties, and electrochemical performances of manganese oxide electrodeposited on ITO substrate was investigated. Lamellar structure was observed in all electrodeposited materials regardless of the applied potential, but the crystallite size, crystallinity, and sheets diameter were affected. Increase in applied potential resulted in higher bandgap energy for all the materials. The electrodeposited material at a potential of 1 V/SCE showed higher specific capacitance and the effect of electrodeposition potential on diffusion and capacitive contributions was analyzed.

Summary: This study successfully fabricated well-aligned WO3 snowflake-like hierarchical arrays with (020) facet perpendicular to the FTO substrate. The fabricated samples were characterized by XRD, SEM, and UV-vis. The SHA photoanode exhibited an impressive photocurrent density of 2.43 mA·cm^-2 at 1.23 V vs RHE, which is 1.76 times higher than the sandwich-like structures. This improved performance can be attributed to the special SHAs and the preferred orientation, which would effectively promote the separation and transfer of carriers.

Summary: The lithium-ion battery (LIB) is widely used as an electrochemical energy storage device due to its high energy density. However, it suffers from poor power performance and cycle performance. These issues can be addressed by incorporating capacitor material into the cathode, resulting in a lithium-ion battery capacitor (LIBC). This review presents the typical structure and working principle of LIBCs and summarizes recent advancements in this field, including non-lithiated and pre-lithiated anode materials, pre-lithiation methods, capacitor materials, suitable separator materials, and electrode engineering for improved electrochemical performance. Future research directions for advanced LIBCs are also discussed based on the existing problems.

Summary: As a representative electrochemical energy storage device, supercapacitors (SCs) have higher energy density than traditional capacitors and better power density and cycle life than lithium-ion batteries, making them extensively used in energy storage. However, there is a lack of understanding of the thermal behaviors and thermal management systems of SCs, which this review aims to address. The review introduces the energy storage mechanisms of SCs and current investigations of thermal behaviors, including heat generation rates, experimental methods, heat generation rate models, and thermal runaway. It also provides an overview of current efforts in different cooling systems and discusses the challenges and future work directions for SCs in thermal behaviors and thermal management systems.
