Summary: The study showed that Si-doping significantly improved the discharge capacity of Li-rich cathodes by around 25%, delayed surface phase transformation, and altered redox behavior. Electron energy loss spectroscopy supported the notion that the surface layer of the cathode had an altered oxygen electronic environment. Si-doping increased oxygen vacancy formation, changed redox couple sequence, effectively controlling the complex charge compensation mechanisms in the cathodes.

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: 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: 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 higher Ni content with less cobalt usage in lithium nickel cobalt manganese oxide cathode materials results in higher power rating and energy density in lithium-ion batteries. Cation doping effectively suppresses the mixing of Ni ions in the lithium layer. Different cationic dopants have varying effects on the structural stability and performance of the cathode material.

Summary: This study reports a novel organic electrode material, hexalithium salt of mellitic acid (Li6C12O12), which shows promising characteristics including low cost, high capacity, non-toxicity, and environmental friendliness for lithium-ion batteries (LIB) and dual-ion batteries (DIB). The electrochemical and spectroscopic analysis confirmed a reversible coordination reaction mechanism based on carboxylic carbonyl and Li+ ions. Li6C12O12 achieved large reversible capacities of 730 mA h g(-1) at 0.21 A/g and 372 mA h g(-1) even at 2 A/g. Moreover, Li6C12O12 electrode exhibited excellent performance in full LIB and DIB, showing high capacity and cycling stability. This work provides a new perspective on designing and tailoring organic electrode materials for high-performance lithium-ion batteries and dual-ion batteries.

Summary: Lithium argyrodite-type electrolytes are promising due to their high ionic conductivity and processability. The influence of halogenation on electrochemical decomposition and chemical degradation mechanism at the cathode interface is investigated. The results show that halogenation leads to increased electrochemical decomposition, more gaseous degradation products, and a decreased interfacial resistance, resulting in higher cell performance.

Summary: A Li2S/LiVS2 core-shell cathode architecture design is reported for all-solid-state Li-S batteries, which improves the kinetics of Li2S cathode by using the shell as a charge-carrier transport vehicle and electron transfer mediator. The solid-state Li2S cell exhibits good rate capability and capacity retention at room temperature, and high active material loading is demonstrated with stable capacity retention. However, the cycle life is limited under high active material loading.

Summary: We have reported a new ion conductor, Na11Sn2SbSe12, which could be a possible candidate for a solid catholyte in composite cathodes for all-solid state Na-batteries. It possesses a room temperature ionic conductivity of 0.15 ± 0.03 mS cm(-1) and an activation energy of 0.39 ± 0.02 eV. Through a combination of Rietveld refinement and electrochemical impedance spectroscopy, we have investigated the sulfide solid solutions, Na11Sn2SbS12-xSex (x = 1 and 6), to understand the structure-property relationships governing ion transport in these materials.

Summary: Conventional Li-S batteries rely on liquid electrolytes, while new electron pair donor (EPD) solvents provide higher sulfur solubility and better sulfur utilization. However, their instability requires the use of an ion-conductive membrane. This study found that even trace amounts of LiOH on the LLTZO surface react with sulfur in EPD solvents, leading to the formation of a resistive layer that impedes Li+ transport. However, modifying the LLZO surface with protective phosphate groups reduces charge-transfer resistance and inhibits the reaction between LiOH and sulfur. The electrolyte cells constructed based on this concept exhibit high sulfur utilization and good stability.
