Summary: This study detected a pattern of sequential group-by-group charging or discharging of Li batteries with phase-separation thermodynamics, and quantitatively predicted the main characteristics of the sequential symmetry breaking events for the first time. It also showed that gradients in liquid phase potential, although extremely small, operate like noise leading to break-up of the homogeneous solution. A bifurcation map was constructed to show the lowest current boundary that ensures a homogeneous lithiation/delithiation as a function of noise level.

Summary: This study classifies the dynamic patterns that emerge during the charging or discharging of Li-ion batteries under galvanostatic conditions. The exchange current function is examined for its effect on the kinetics. Nonuniformity in the parameters leads to noise that masks the behavior. The full model exhibits symmetry breaking events, even in the absence of noise, due to the perturbation effect of the liquid potential gradient.

Summary: Cyclic aging of lithium-ion batteries leads to capacity decline, impedance increase, and polarization deepening. A study was conducted on commercial 18650 lithium-ion batteries using fast charge/discharge cycles to determine the influence of cyclic aging on safety performance. The results showed a nonlinear three-stage change in aging, with higher charge/discharge rates exacerbating the aging state. Thermal abuse tests revealed that aged cells have better thermal stability but a higher risk of thermal runaway, possibly due to flammable gas and exothermic reactions during fast charge/discharge processes. This study highlights the potential for aged cells in products like electric vehicles to trigger thermal runaway.

Summary: Experimentally, hard carbons (HCs) synthesized under different conditions always show various alkali-ion storage capabilities. Here, fullerene (C-60), a heteroatom-free and structure-confirmed precursor, is chosen to build pure carbon models (C-60-T-s) for exploring the correlations between inherent characteristics and alkali-ion storage behaviors in HCs. The electrochemical results indicate that the C-60-800 sample exhibits the highest specific capacity and best rate capability for Li+, Na+, and K+ storage. Various spectrometric characterizations and theoretical simulations demonstrate that the extra capacity of C-60-800 mainly originates from the higher ratio of sp(3) and sp(2)-hybridized carbon atoms (sp(3)/sp(2)-C). This work presents a novel orbital hybridization state-related strategy for designing high-capacity electrode materials of alkali-ion batteries.

Summary: This study thoroughly investigates the influence of Mg cations, F anions, and their co-doping on the atomic structures of LiCoO2 and their impact on electrochemical performance. The results show that MgO4 tetrahedra can suppress charge transfer and reduce pseudo-JTE, while F doping increases ligand-field strength but decreases structural stability. In contrast, Mg/F co-doping generates CoO5F-MgO4F2-CoO5F medium-range orders, which reduce structural distortion and charge transfer, leading to improved electrochemical performance.
