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: In this study, Ni0.8C0.1Mn0.1(OH) precursors with hexagonal morphology were synthesized via a hydrothermal method, leading to the successful preparation of highly crystalline micrometer Ni-rich single-crystal LiNi0.8Co0.1Mn0.1O2 cathode materials with excellent dispersion at relatively lower calcination temperature and excess lithium ratio. These single-crystal cathode materials exhibited better initial capacity and excellent capacity retention compared to traditional commercial Ni-rich polycrystalline cathodes, showing promising potential for high-performance Li-storage structures.

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: Large-scale popularization and application of lithium-ion batteries have increased its prominence and the requirements for higher energy density. We have designed and synthesized carbon-coated porous silicon structures using diatomite and polysaccharides as raw materials to improve conductivity and structural stability of the silicon anode. The electrode materials constructed exhibit porous structures that provide fast transport channels for lithium ions and release stress caused by volume expansion.

Summary: In this study, a method of short-time high-temperature sintering combined with low-temperature heat preservation was proposed to prepare LiNi0.6Co0.6Mn0.2O2 (NCM622) single crystal materials. The prepared NCM622 showed excellent cycling stability and ordered layered structure. This method can significantly reduce the preparation cost and can be applied to the synthesis of other single-crystal materials with excellent electrochemical properties.

Summary: Layered cathode materials, such as LiCoO2, have been synthesized for Li-ion batteries using a direct solution-calcination strategy. The addition of polyvinylpyrrolidone (PVP) as a functional agent in the synthesis process helps to eliminate surface Li residues and promote a uniform particle distribution. The solution-calcined cathode material shows improved cycling stability and rate capability compared to commercial LCO, with suppressed phase transition. This research provides a simple and versatile method for the synthesis of cathode materials, avoiding complicated steps and the formation of unwanted residual lithium compounds.

Summary: TiO2-coating of LNMO by ALD was studied to stabilize the cathode/electrolyte interface and mitigate TM ion dissolution. The TiO2 coatings were found to be uniform and resulted in improved capacity retention in LNMO||graphite full-cells. Thinner cathode electrolyte interphases and solid electrolyte interphases were observed on the TiO2-coated samples, indicating retardation of TM dissolution.

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.
