This study evaluates electrochemical voltage-range and voltage-profile regarding electrodes of insertion (intercalation) batteries. The phrase “voltage-range” expresses the difference between obtained maximum and minimum potential for the cells. It also can be called as operating voltage-range, working voltage-range, electrochemical voltage-range, or voltage window. This paper proposes a new notion regarding electron density of states, i.e. trans-band, which can be implemented to justify the voltage -range and -profile, by means of Fermi levels’ alignment. Voltage -range and -profile of a number of insertion electrode materials are clarified by the proposed theoretical approach, namely LiMn2O4, Li2Mn2O4, ZnMn2O4, LiFePO4, LiCoO2, Li2FeSiO4, LiFeSO4F, and TiS2. Moreover, the probable observed difference between charge and discharge profile is explained by the approach. The theoretical model/approach represents a number of important concepts, which can meet some scientific fields, e.g. electrochemistry, energy storage devices, solid state physics (DFT), and phase diagrams. By means of DFT calculations, this paper deals with quantizing the energy of electrochemical reactions, justifying the configuration of voltage-profile, and explaining the origin of the voltage-range. Accordance with the experimental observations suggests that this paper can extend boundary of quantum mechanics toward territories of classical thermodynamics, and boundary of the modern thermodynamics toward kinetics. Opening a new horizon in the related fields, this paper can help tuning, engineering, and predicting cell-voltage behavior.

The rapid developments of the Internet of Things (IoT) and portable electronic devices have created a growing demand for flexible electrochemical energy storage (EES) devices. Nevertheless, these flexible devices suffer from poor flexibility, low energy density, and poor dynamic stability of power output during deformation, limiting their practical applications. Carbon nanofibers (CNFs) with high conductivity, good flexibility, and large‐scale preparation are regarded as promising electrodes for flexible EES devices. Based on the issues of current flexible EES devices, this review presents various strategies from the design of CNFs‐based electrodes to the fabrication of devices and overviews their applications in various flexible metal ion/air batteries (Li/Na/K‐ion batteries, Li‐S batteries, metal–air batteries, and other novel secondary batteries) and supercapacitors. Finally, the remaining challenges and perspectives on the CNFs‐based flexible EES devices are proposed to provide guidance for the researchers concentrating on high‐performance flexible EES devices.

Cu2MSnS4 (M = Co,Mn,Fe,Mg) are emerging as potential photovoltaic absorbers owing to their exceptional properties. However, a large open‐circuit voltage (VOC) deficit caused by the unfavorable band alignment with the toxic CdS buffer limits their overall efficiency. Therefore, identifying an appropriate alternative buffer is essential for improving performance. Herein, solar cell capacitance simulator in one dimension (SCAPS‐1D) is employed to theoretically design and analyze these emerging solar cells using TiS₂ as a substitute for CdS. The investigation focuses on various parameters, including buffer, absorber, and interface characteristics, to evaluate their impacts on performance. Remarkably, the highest efficiencies achieved with TiS₂ buffers are 27.02%, 27.04%, 30.04%, and 30.26% for Cu2MSnS4 (M = Co,Mn,Fe,Mg), respectively, surpassing CdS by 1.36, 1.76, 1.23, and 1.15 times. The high efficiencies obtained are associated with reduced electron barrier of −0.24 eV, −0.4 eV, −0.04 eV, and 0.08 eV at TiS2/Cu2MSnS4 (M = Co,Mn,Fe,Mg) interface, lower accumulation capacitance, significantly higher built‐in potentials (>1.2 V), lower VOC losses (<0.35 V) and improved recombination resistance in TiS₂ solar cells compared to CdS. Additionally, the study addresses the experimental challenges and strategies necessary for the practical fabrication of TiS2‐based solar cells, providing valuable insights for the photovoltaic community.
