Two‐dimensional molybdenum disulfide (MoS2) has been recognized as a promising anode material for lithium‐ion batteries (LIBs) due to its high theoretical capacity, but its rapid capacity decay owing to poor conductivity, structure pulverization, and polysulfide dissolution presents significant challenges in practical applications. Herein, triple‐layered hollow spheres in which MoS2 nanosheets are fully encapsulated between inner carbon and outer nitrogen‐doped carbon (NC) were fabricated. Such an architecture provides high conductivity and efficient lithium‐ion transfer. Moreover, the NC shell prevents aggregation and exfoliation of MoS2 nanosheets and thus maintains the integrity of the nanostructure during the charge/discharge process. As anode materials for LIBs, the C@MoS2@NC hollow spheres deliver a high reversible capacity (747 mA h g−1 after 100 cycles at 100 mA g−1) and excellent long‐cycle performance (650 mA h g−1 after 1000 cycles at 1.0 A g−1), which confirm its potential for high‐performance LIBs.

MoS2 has attracted tremendous attention as a promising electrode material for rechargeable alkali metal ion (Li+, Na+, K+) batteries due to its high capacity and low cost. However, the practical application of MoS2 for energy storage has not been achieved yet, which is restricted by its intrinsic charge‐storage behavior. Debates still exist in this field although great efforts have been made to reveal alkali metal ion (Li+, Na+, K+) storage mechanism of MoS2. This Minireview aims to provide an analysis and summary of the related phase conversion, structure collapse, and loss of active material in a MoS2 electrode during the intercalation/extraction process of alkali metal ions. Hence, the fundamental understanding about the charge storage in MoS2 is of importance for the rational design of MoS2 electrodes with excellent electrochemical performance.

With the acceleration of the Fourth Industrial Revolution, the development of information and communications technology requires innovative information storage devices and processing devices with low power and ultrahigh stability. Accordingly, bioelectronic devices have gained considerable attention as a promising alternative to silicon-based devices because of their various applications, including human-body-attached devices, biomaterial-based computation systems, and biomaterial–nanomaterial hybrid-based charge storage devices. Nanomaterial-based charge storage devices have witnessed considerable development owing to their similarity to conventional charge storage devices and their ease of applicability. The introduction of a biomaterial-to-nanomaterial-based system using a combination of biomolecules and nanostructures provides outstanding electrochemical, electrical, and optical properties that can be applied to the fabrication of charge storage devices. Here, we describe the recent advances in charge storage devices containing a biomolecule and nanoparticle heterolayer including (1) electrical resistive charge storage devices, (2) electrochemical biomemory devices, (3) field-effect transistors, and (4) biomemristors. Progress in biomolecule–nanomaterial heterolayer-based charge storage devices will lead to unprecedented opportunities for the integration of information and communications technology, biotechnology, and nanotechnology for the Fourth Industrial Revolution.
