Summary: The study fabricated an aqueous Zn2+/Li+ hybrid-ion battery using LiV3O8 nanorods as cathode, metallic Zn as anode, and 3M Zn(OTf)(2) + 0.5M LiOTf aqueous solution as electrolyte. The hybrid-ion battery showed significantly improved cycle performance compared to batteries using pure 3M Zn(OTf)(2) electrolyte, with an impressive capacity retention of 87.0% after 4000 cycles at 5A g(1), due to the inhibitory effect of the hybrid electrolyte on the formation of irreversible by-products and Zn dendrite growth.

Summary: The yolk-shell-structured NiCo2S4 spheres were synthesized as cathode catalysts for Li-O2 batteries, and the optimal sulfidation time was found to be 18 hours. The battery with YS-NCS-18 as the catalyst exhibited the highest specific capacity, best rate capability, and most stable cycling performance, due to the largest gap between the yolk and shell and the highest catalytic activity of the (531) surface.

Summary: Si-based blended anodes composed of artificial graphite and graphene-coated SiOx particles are reported to have durable and high-energy properties. The graphene coating reduces electrode swelling and increases initial Coulombic efficiency, leading to increased areal capacity. The self-adaptive behavior of graphene mitigates mechanical damage and maintains electron conduction pathways, improving the reversibility of charge-discharge reactions. The blended anode exhibits good cycling stability and high volumetric capacities, demonstrating the applicability of high-capacity Si-based anodes for LIBs.

Summary: In this study, the capacity of graphene|electrolyte|Li laboratory cell was tested at different currents. The impedance of the Li4Ti5O12|electrolyte|Li laboratory and commercial Li-ion cells was also measured. The research discusses various factors that affect Li-ion batteries, such as cathode and anode material capacity, battery polarization, heat dissipation, volume changes, capacity under non-equilibrium conditions, pseudocapacitive behavior, and battery safety. The results show that battery capacity may vary with current and polarization, and the measurement process may affect the determined capacity value.

Summary: Fast charging of Li-ion cells faces challenges including accelerated capacity fade and inferior charging capability. Apart from the well-known issues of Li plating and voltage polarization, there are hidden factors such as failure of the solid electrolyte interphase, structural degradation of cathode materials, and high activation energies of Li+ ions in the electrolyte. Understanding these factors can help propose solutions to the fast-charging problems.

Summary: The sluggish kinetics of sulfur reactions on the cathode and the inadequate lithium deposition/stripping reversibility on the anode are successfully mitigated by using a single cathode modifier, In2Se3, which catalyses the polysulfide reactions on the cathode and improves lithium deposition/removal reversibility on the anode through the formation of a LiInS2/LiInSe2 containing solid electrolyte interface. This single modification approach shows excellent performance in Li-metal anode-free Li-S batteries, achieving 60% capacity retention and an average Coulombic efficiency of 98.27% after 160 cycles.

Summary: Combining hollow yolk-shell structure and surface modification is an effective strategy to enhance the performance of lithium-ion battery anodes. The use of a nanosheets-coated multiple-layered SnO2@NiMoO4 composite demonstrates the synergistic effect between multi-layered SnO2 microspheres and NiMoO4 nanosheets, leading to improved electrochemical properties. The reversible capacity of the SnO2@NiMoO4 anode is competitive and shows potential for developing high-performance Li-ion battery systems.

Summary: In this study, Ga2O3 nanotubes coated with N-doped carbon layers were prepared using MoO3 nanorods as sacrificial templates followed by a poly-dopamine coating and heat treatment process. The resulting tubular structure provided cavities for volume changes of the Ga2O3 and shortened the migration path of Li ions and electrons, leading to improved cycling stability and rate performance of the battery.

Summary: The storage capacity and reliability of Lithium-ion batteries has significantly improved in recent years. This study focuses on optimizing the cathode material of the system, which is based on Nickel-Manganese-Cobalt (NMC) mixed oxides. Increasing the Ni content in these mixed oxides reduces the need for expensive and hazardous Co. However, a high Ni content poses challenges such as irreversible Li site occupation, structural phase transformations, and surface contaminations caused by Ni reactivity.
