Special Issue Information

Dear Colleagues,

Research on new materials has constantly been driving the rapid development of energy storage and conversion technologies, such as Li-ion batteries, metal–air batteries, and next-generation batteries. In recent years, advanced materials have provided enormous opportunities to create batteries with higher energy density, better cycling performance, improved safety, lower cost, and longer cycling life. Research on novel materials will continue to grow and gain importance in more applications, including all-solid-state batteries.

In this Special Issue, we focus on advanced materials directed towards applications in the battery field, especially in the advancement of electrode materials and new electrolytes, including, but not limited to, new anode materials, cathode materials, electrolyte additives, solid-state electrolytes, electrode additives, and interphases. This Special Issue aims to demonstrate the latest updates and future perspectives regarding advanced materials for batteries.

In this work, electrospun nanofiber membranes are investigated as separators for lithium batteries. Membrane consisting of polyacrylonitrile-polycaprolactone mixtures were produced following a combinatorial approach inspired by design of experiments to identify the relationships between process parameters and microstructural properties. The microstructure of the non-woven fibrous mats was characterized by scanning electron microscopy to measure thickness and fiber distribution. Temperature and relative humidity during membrane deposition were also tracked to include them in the statistical analysis and highlight their influence on the properties of the resulting membranes. The functional evaluation of the membranes was conducted by electrochemical impedance spectroscopy, after soaking the membrane in the electrolyte, to measure ion transport properties. All the separators showed specific conductivities higher than 1.5 × 10−3 S. The electrochemical performance was also evaluated when the membranes were used as actual separators in coin-cells assembled in-house, stacking the electrolyte-soaked membranes between a lithium anode and a LiFePO4-based cathode. Among all, the PAN/PCL 50:50 showed excellent cycling stability, with a high initial capacity of 150 mAhg−1 and a coulombic efficiency of 99.6%. Full article

Due to poor electrical conductivity and significant volume change during the lithiation/delithiation process, the application of silica anode materials for lithium-ion batteries is severely limited. Here, SiO2 nanotubes with a uniform and complete carbon layer were prepared employing ZnO nanorods as templates. The controllable wall thickness of SiO2 nanotubes is about 11 nm, and the thinner wall reduces the lithium-ion diffusion distance and boosts performance. The uniform and complete carbon layer leads to a perfect dispersity of SiO2 nanotubes, enhances the overall electrical conductivity, and also buffers the mechanical stresses caused by volume change, which helps to exhibit high specific capacity and a long cycle life. The nanotubular SiO2@C composite reveals a high discharge specific capacity of about 526.3 mAh g−1 at a current density of 1 A g−1 after 500 cycles without significant capacity fade. In addition, it demonstrates excellent rate performance, which can maintain above 420 mAh g−1 even at a current density of 5 A g−1. The strategy may be adopted to prepare other anode materials as well. Full article
