Summary: The thermal decomposition mechanism of a Li-rich rock salt cathode material Li1.3Mn0.4Nb0.3O2 was studied, revealing its poor thermal stability and higher susceptibility to thermal runaway compared to state-of-the-art cathode materials. The reaction between the transition metal and electrolyte was identified as the limiting factor for its thermal stability. These findings address important knowledge gaps and provide insights for improving the safety and performance of Li-ion batteries.

Summary: Layered lithium nickel manganese cobalt oxide or NMC type cathode materials are widely used in lithium-ion batteries. However, the traditional production method requires large amounts of water and can generate waste. An alternative all-dry synthesis method using thermal interdiffusion is presented, which allows for atomic scale mixing and greatly reduces preparation time and cost. The complications and applicability of using a thermally synthesized precursor for layered cathode material are discussed.

Summary: In this study, three samples were prepared by strategically formulating the Li+ sites of Li-CoOx composite, and their structures and componential interactions were characterized by various techniques. After Ag decoration, the Li+-Co3+-O2- connections uniquely caused a strong binding of Ag species with catalyst host, resulting in an increased amount of reactive oxygen and improved formaldehyde degradation efficiency and mineralization capacity. Additionally, Ag@L-CO exhibited better resistance to moisture and aromatic compounds omnipresent in indoor air compared to other samples.

Summary: High-entropy oxides with rock salt structure are materials with intriguing functional properties, but elements like Ni in their composition pose a threat to human health. In this study, we successfully develop a Ni-free high entropy rock salt by replacing nickel with manganese. Through suitable thermal treatment, we obtain samples with high density and good phase purity, and demonstrate the electrical properties of the materials.

Summary: This review article summarizes recent research development on a new class of electrode materials with a cation-disordered rock salt structure for energy storage applications. Historically, oxide-based electrode materials with the disordered rock salt structure are regarded as electrochemically inactive. However, recent experimental and theoretical research reveals that many oxides with the disordered rock salt structure can be utilized as high-capacity electrode materials, which deliver a much larger reversible capacity compared with traditional and cation ordered layered materials used for practical battery applications. For these emerging electrode materials, higher energy density is achieved relying on anionic and/or cationic redox as multi-electron reactions. Moreover, this anionic/cationic redox for Li-excess materials with the rock salt structure is effectively activated for nano-sized materials. These new trends for the material design on high-capacity electrode materials are highlighted and the future direction to design Li/Na insertion materials for energy storage applications is outlooked.

Summary: Li-rich cation-disordered rock-salt oxides (DRXs) have high capacity but suffer from serious performance degradation due to the growth of a LiF-rich cathode electrolyte interface (CEI) layer, which is caused by oxygen loss, over-reduction of redox-active TMs, TMs dissolution, and irreversible phase transition. This research provides a fundamental understanding of interfacial stability in DRX cathode materials.

Summary: Cation-disordered rock-salt (DRX) materials have gained significant attention as potential cathode candidates for high-capacity lithium-ion batteries (LIBs). In this study, a large supercell model of DRX material Li1.16Ti0.37Ni0.37Nb0.10O2 (LTNNO) was developed using the reverse Monte Carlo (RMC) method in combination with neutron total scattering. Through experimental analysis and density functional theory (DFT) calculations, the existence of short-range ordering (SRO) and element-dependent behavior of transition metal (TM) site distortion were confirmed. It was found that site distortions affect the diffusion barrier for Li+ ions, expanding the theoretical percolating network of Li in DRX materials. The newly developed characterization method provides valuable insights for the design of improved DRX materials.

Summary: An in-depth study of Li4Mn2O5 reveals that the anomalously high charge and discharge capacity in lithium cells is caused by the electrochemical decomposition of Li2O and the reduction of Mn. There is no evidence of reversible oxygen redox contributing to the capacities. The over-reduction is worsened by high charging limits, resulting in rapid capacity fading. Adding spinel LiMn2O4 improves the cycling behavior but decreases the discharge capacity.

Summary: This paper provides an overview of research on lithium and sodium layered materials as positive electrodes in lithium (sodium)-ion batteries, focusing on the solid-state chemistry's role in discovering new materials and optimizing properties for different applications. Layered structures, especially lithium-based ones, are considered as the best candidates for high energy density batteries for mobile applications. Through high-temperature solid-state chemistry, many substituted phases have been obtained to stabilize the layered structure and increase the specific capacity.

Summary: A better control of the metal-electrolyte interface is essential for the development of rechargeable magnesium batteries. Coating the magnesium surface with an amalgam layer formed in contact with a mercury droplet shows an improvement in the plating/stripping process. However, detailed investigation reveals that the amalgam layer undergoes substantial chemical and morphological changes during cycling, indicating that it doesn't act as a protective coating but rather as an independent electrode material.

Summary: Layered oxides with the composition NaxMO2 have attracted attention for their composition diversity and promising electrochemical performances in sodium-ion batteries. This study attempts to synthesize sodium-rich P-type NaxMn2/3Ni1/3O2 and NaxMn1/2Ni1/2O2 and investigates their electrochemical behavior. The optimization of the synthesis protocol led to stabilize only P3-type single-phases. The investigation shows that the actual Na content is limited but still higher than conventionally reported for most of P3-type layered oxides.

Summary: All solid-state lithium batteries (ASSLBs) are considered to have substantial advantages over conventional liquid electrolyte based lithium ion batteries (LIBs), but the failure mechanisms of ASSLBs are not well understood, requiring particular attention. Recent progress in in situ transmission electron microscopy (TEM) studies of ASSLBs has revealed novel electro-chemo-mechanical coupling phenomena and provided mechanistic insights, demonstrating the general applicability of in situ TEM for elucidating fundamental mechanisms and providing design guidance for the development of high-performance ASSLBs. Challenges and opportunities for in situ TEM studies of ASSLBs are discussed.
