Summary: Graded electrodes in Li-ion batteries can improve battery performance by reducing degradation rates and increasing capacity at high discharge rates. However, the mechanisms and conditions for achieving these performance benefits are not fully understood. This study develops an electrochemical model and validates it using experimental data, revealing that a localized carbon-enriched region at the electrode/current collector interface can decrease overpotential distribution and improve charge transfer resistance and impedance.

Summary: This paper introduces a novel fast charging procedure that reduces the deposition of metallic lithium on the surface of the negative electrode by regulating the current through the correlation between electrode polarization and anode potential. The linear relationship between cell voltage and anode potential is shown independently of current rate, temperature, and initial SOC. By implementing anode potential regulation based on this relationship, the risk of unwanted lithium plating is significantly reduced. The advantage of this implementation is that it does not require a P2D model on a micro-controller, making it suitable for embedded systems.

Summary: This study investigates the effect of oxide modification on the fast lithium intercalation on cathode surfaces using in situ neutron reflectometry. The results show that the modified cathode exhibits superior rate capability due to the formation of a dense cathode-electrolyte interphase (CEI). The fast desolvation of lithium on the CEI contributes to the high rate capability of surface-modified cathodes.

Summary: To address the issue of lithium (Li) plating on graphite anodes during fast charging, Li plating regulation and morphology control are proposed. A Li plating-reversible graphite anode is achieved through a localized high-concentration electrolyte (LHCE), resulting in high reversibility and stability. The stable LiF-rich solid electrolyte interphase (SEI) enables a higher average Coulombic efficiency (99.9%) and reversibility of Li plating (99.95%). A self-made LiNi0.5Mn0.3Co0.2O2 | graphite pouch cell exhibits a competitive capacity retention of 84.4% even at high current (7.2 A) after 150 cycles, demonstrating the potential for high-performance fast-charging batteries.

Summary: Recently, there has been increasing interest in using nanostructured materials with oxygen defects as electrode materials for lithium-ion batteries (LIBs). However, the relationship between surface morphology, nanostructuring, oxygen defects, and Li-storage characteristics remains unclear. In this study, one-dimensional, porous, and oxygen-deficient nanofibers of MgMn2O4 (MMO) were fabricated and analyzed for their Li-storage performance. The MMO-600 sample, which exhibited a high number of oxygen vacancies, showed excellent reversible specific capacity, rate capability, and cyclic stability as a binder-free LIB anode. Furthermore, MMO-600 demonstrated better capacity at high rates compared to MMO-450 and MMO-750. In addition, the feasibility of MMO-600 in a full cell configuration with a binder-free LiNi1/3Mn1/3Co1/3O2 cathode was investigated, showing promising energy density. (c) 2023 Elsevier B.V.
