Summary: This study investigates the application of Prussian blue analogues (PBAs) as electrode materials for aqueous ammonium ion batteries (AAIBs). A PANI/Na0.73Ni[Fe(CN)(6)](0.88) hybrid (PNFF) is synthesized using a covalent bond assisted engineering with in situ polyaniline (PANI) polymerization, combining the high conductivity of PANI and the stability of PBAs. It is found that the PANI content affects the electrochemical performance of PNFF, and an optimized PANI content results in enhanced reversible capacity and cycling stability. The ammonium storage mechanism of PNFF is investigated using in situ Raman and ex situ XPS/FTIR analysis, and a durable aqueous NH4+ full cell is assembled using a polyimide@MXene anode.

Summary: Polysaccharides, such as cellulose sulfate lithium (CSL) with strong adhesion, are synthesized and used as binders for LiFePO4 (LFP) cathode. Compared to conventional polyvinylidene difluoride (PVDF) binder, LFP cathode using CSL (LFP-CSL) exhibits lower polarization and better rate performance due to higher lithium-ion conductivity. CSL binder also maintains the integrity of the LFP cathode structure during cycling, resulting in a discharge capacity of 133.4 mAh g(-1) and remarkable cycle stability after 300 cycles at 1C.

Summary: The increasing demand for electric vehicles and the rapid consumption of rechargeable lithium-ion batteries call for the recycling of spent cathode active materials (CAMs) to reduce hazardous wastes and provide raw materials for battery production. Traditional methods such as direct calcination of polyvinylidene fluoride (PVDF) binder have drawbacks of high energy consumption and toxic gas release. This study explores an environmentally friendly and effective alternative using different lithium salts, and achieves high peel-off efficiency with LiOAc and LiNO3. The mechanism of PVDF decomposition is proposed.

Summary: The exponential growth in production of electric vehicles has led to an increased demand for low-cost, high-performance lithium-ion batteries. However, concerns over the availability of cobalt, a high-cost and rare material used in high-nickel cathodes, may impact the price due to supply constraints. Developing cobalt-free high-nickel cathode materials, such as LiNi1-x-yMnxAlyO2, is necessary to address the reliance on cobalt and its high cost.

Summary: This study reports a strategy to suppress the lattice oxygen loss in a Ni-rich material at high charging voltage by a simple Sr treatment. The Sr treatment forms a Sr-based sub/surface integrated layer and induces atomic rearrangement to form a Sr-based perovskite-like structure. The perovskite-like structure can adsorb oxidized oxygen and reduce it back to inhibit the movement of oxidized oxygen anions during charging. In addition, bulk doping suppresses the migration of Ni at high charging voltage. The modified material exhibits significantly enhanced high-voltage cycle stability.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
