Summary: A sacrificial cathode additive as a pre-metallation method has been used to ensure adequate metal sources for advanced energy storage devices, but struggles with controlling the decomposition potential of the additive. A molecularly compensated pre-metallation strategy has been achieved through Kolbe electrolysis, manipulating the electrochemical oxidation potential of a metal carboxylate through the bonding energy of the oxygen-metal moiety.

Summary: This study evaluated the effects of cathodic voltage-controlled electrical stimulation (CVCES) on the pH near a titanium electrode using a combination of experimental measurements and computational modeling. The results showed that a greater cathodic potential led to a more significant alkalization effect on the microenvironment, with pH increasing rapidly at a distance of 10 micrometers from the polarized surface. The computational model developed demonstrated good agreement with the experimental data and shows promise as a tool for guiding the development of antimicrobial electrochemical treatment methods.

Summary: Metal-free organic electrode materials have been widely studied due to their designable structures and tunable electrochemical properties. This article introduces a new p-type polymeric cathode material, poly(2-vinyl-5,10-dimethyl-dihydrophenazine) (PVDMP), with a theoretical capacity of 227 mAh g(-1). The study investigates the electrochemical behavior of PVDMP-based cathode, which depends on the doping of two anions to maintain electroneutrality during oxidation. The optimal conditions for PVDMP cathode are identified, resulting in high initial capacity and excellent cycling stability.

Summary: In this study, the insulator-metal transition of LiCoO2 was investigated using operando Raman spectroscopy, DFT calculations, and a sample volume model. It was found that LCO follows a two-phase transition route at low cycling rates, but a solid-solution transition route is favored at higher rates, explaining its competitive rate capabilities. The research provides unique insights into fundamental processes governing the performance of state-of-the-art cathode materials for Li-ion batteries.

Summary: Due to the excellent discharge capacity provided by oxygen redox activity, Li-rich layered oxide positive electrode materials have attracted great attention. However, there is still no consensus regarding the role of ionocovalency of transition metal-oxygen chemical bonding in the reversibility of oxygen redox and the local crystal and electronic structure transformations. In this study, we successfully manipulated the cationic/anionic redox contributions to the overall electrochemical activity and investigated the importance of enhancing the covalency of the TM-O bonding for anchoring the reversibility of the charge compensation mechanism.

Summary: The solid electrolyte interphase (SEI) is a critical component of Li-ion batteries, but its complex nature and lack of appropriate tools hinder the understanding of its governing mechanisms. In this study, operando Raman spectroscopy and online electrochemical mass spectrometry were used to investigate the formation of SEI on Au in a model electrolyte. The electrolyte itself and cell contaminants were found to contribute to the formation of SEI through stepwise electrochemical/chemical processes. Raman spectroscopy provided insights into the mechanisms, but additional techniques were needed for spectral interpretation.

This study investigated the initial plating and stripping cycles of a magnesium model electrolyte using electrochemical quartz crystal microbalance with dissipation monitoring (EQCM-D). The results showed the formation of an irreversible deposited Mg interphase during the initial cycles and revealed the growth of a porous layer during Mg stripping. The study provides valuable information on the interphase formation and its dynamic behavior.

Summary: Transition metal (TM) dissolution is influenced by cathode-electrolyte interaction and affects both the loss of redox-active material from the cathode and the stability of the solid electrolyte interphase (SEI) at the counter electrode. The limited anodic stability of typical carbonate-based electrolytes, specifically ethylene carbonate (EC), poses challenges for high-voltage cathode performance. Tetramethylene sulfone (SL) has been used as a co-solvent to investigate the TM dissolution behavior of LiN0.8C0.17Al0.03 (NCA) and LiMn2O4 (LMO) as a more anodically stable substitute for EC. Electrolytes containing SL show reduced TM dissolution compared to EC, but they have lower cycling stability due to their reduced ability to support Li-ion transport.
