Summary: Conversion cathode materials are of interest for secondary batteries due to their high theoretical energy and power density, but practical application is limited by issues such as poor cyclability. A pseudo-two-dimensional model has been developed for FeS2, a material that undergoes intercalation followed by conversion during discharge, revealing that solid-state diffusion and electrical transport limitations through the converted shell material are the leading loss mechanisms. Additionally, simulations comparing polydisperse and monodisperse systems show that polydispersity has minimal effect on intercalation behavior but leads to capacity loss during the conversion reaction.

Summary: Understanding the ion intercalation and degradation mechanisms is crucial for developing high-rate battery electrodes. Operando optical scattering microscopy is used to study single-particle kinetic state-of-charge heterogeneities and cracking in high-rate Li-ion anode materials. This study demonstrates the power of optical scattering microscopy in tracking rapid non-equilibrium processes that would be inaccessible with established characterization techniques.

Summary: This study investigates the rechargeable Li-FeS2 system using various characterization techniques and an ionic liquid electrolyte. The results reveal new reaction pathways and products during the initial lithiation and subsequent cycling of FeS2. It is found that Li2S and hexagonal FeS are formed as intermediate phases during the initial lithiation, and greigite (Fe3S4) is produced as a charge product during the rechargeable reaction, which differs from previous reports. The formation of Fe3S4 is dependent on temperature and the availability of sulfur. Upon further cycling, Fe3S4 transforms to a lower sulfur content iron sulfide phase. The findings highlight the importance of retaining sulfur in the active material for capacity retention.

Summary: Sodium-ion batteries (SIBs), a promising alternative to lithium-ion batteries (LIBs), are essential for future electric vehicles and energy storage systems. While the recycling of spent SIBs and LIBs face similar environmental and economic challenges, the recycling of SIBs is more economically demanding. Proactive strategies must be implemented during the early commercialization stage to ensure easy recycling, low operation costs, and optimal efficiency of SIBs. This Perspective article provides an overview of the components of SIBs, discusses recycling strategies, and highlights the challenges and future prospects of SIB recycling.

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: As the most popular power source for energy storage equipment, lithium-ion batteries (LIBs) offer advantages such as high-energy density, high power, and long cycle life. However, the performance of LIBs is hindered by increased impedance and reduced lithium-ion diffusion at low temperatures, leading to poor electrochemical activity and decreased capacity. This review comprehensively examines the factors affecting the performance of LIBs at low temperatures and highlights methods and mechanisms for improving the capacity of various electrode materials.

Summary: Sodium-ion batteries are being extensively studied and commercialized as an alternative to lithium-ion batteries. Na-deficient P2-type layered oxides are promising cathode materials due to their fast sodium diffusion and high charge/discharge rates. However, a structural transition and capacity degradation occur when sodium is extracted at high potentials. This study investigates the acoustic emission (AE) of P2-type layered oxide cathodes with varying entropy, revealing a relationship between entropy, phase transition, and detected AE signals.
