Summary: In this study, we successfully constructed a flexible electrode with a hollow core-shell structure using metal-organic frameworks as templates. The electrode exhibited excellent lithium storage capacity and flexibility due to its rich active points for electrochemical reactions, improved electrical conductivity, and enhanced diffusion of lithium ions. This research provides a new idea for the application of flexible devices.

Summary: In theory, red P is a promising anode material for Li-ion batteries, but its electrochemical performance is challenged by P pulverization. Composites of P and C, especially with carbon nanotubes as additives, dramatically improve the stability of the anode. The adherence of the C/P composite to the current collector is ensured by the mechanical elasticity and superior P uptake of nanotubes.

Summary: Magnesium ion batteries have attracted attention for their high theoretical capacity and low cost. However, the slow diffusion rate caused by the strong polarization effect of Mg2+ has hindered their development. In this study, a binder-free polyaniline array/carbon cloth cathode was designed and synthesized for improved electrochemical performance in MIBs.

Summary: This study compares the electrochemical performance of commercial single-walled carbon nanotubes (SWCNTs) with red phosphorus deposited on the outer surface and/or encapsulated in internal channels for lithium-ion batteries. Encapsulated phosphorus demonstrates higher reaction rates and slight loss of initial capacity compared to external phosphorus. The support of SWCNTs and tubular space contribute to the stable operation and formation of chain phosphorus structures.

Summary: A novel flexible self-support carbon cloth-based NH4V4O10 cathode was fabricated via a simple hydrothermal method. The carbon cloth acts as a flexible interconnected conductive network and provides uniform nucleation centers, effectively reducing agglomeration. The synthesized NH4V4O10 nanoribbons exhibit a unique micropore structure with enlarged interlayer spacing, ensuring rapid ion transfer and enhanced storage capacity. This high-performance flexible battery shows outstanding operation stability at low temperatures and maintains 76% energy retention after 100 cycles at a 0.5 A g 1 current density.

Summary: In this study, three types of flexible 3D-interconnected carbon nanofibers were prepared and used as substrates for vertically grown ultrathin MoSe2 nanosheets. The resulting composites were employed as freestanding anodes for lithium-ion batteries, with the hollow multi-nanochannel structure of NHMCFs delivering the highest capacity after 400 cycles at 1 A g-1. The multi-nanochannel structure in NMCFs and NHMCFs helps alleviate volume changes during charge-discharge processes, while the uniform coating of MoSe2 nanosheets on NHMCFs increases mass loading and capacity.

Summary: In the past decade, the rapid development of lithium-ion battery (LIB) energy storage systems has supported the efficient operation of renewable energy stations. However, the current LIB falls short of meeting the demand for a longer service life. Prelithiation technology has been widely studied to improve the service life of LIBs, and this review summarizes different prelithiation methods. It also analyzes the challenges and potential of large-scale industrialization of prelithiation technology based on industry compatibility, prelithiation efficiency, and energy density. Furthermore, the future trends of LIB improvement using overlithiated cathode materials are discussed.
