Special Issue Information

Dear Colleagues,

Advanced materials for Li-based next-generation batteries aim to cover up-to-date and innovative development and research on Li next-generation batteries. Innovative strategies and competitive designs for developing high-quality electrodes for the indigenous production of Li-based next-generation batteries are urgently required. Statistics have revealed electric vehicles (EVs) to be the future and have suggested that lithium will play an important role. Hence, it is an active area of scientific investigation. The goal is to develop high-performance batteries that can store more energy, charge faster, and last longer than current lithium-ion batteries, while meeting the growing demand for energy storage in a range of applications, from electric vehicles to renewable energy systems.

The objective of the Special Issue is to encourage the presentation of research that encompasses developing high-capacity cathode materials that may include lithium-rich layered oxides, high-voltage spinel oxides, and sulfur-based cathodes to name a few; improving the performance of anode materials such Si and Li metal that can improve the charging speed and efficiency of batteries; developing new solid electrolytes and electrode materials; engineering nanostructured materials; developing new manufacturing processes; and exploring new battery chemistries, such as lithium-sulfur and lithium-air batteries. The knowledge thus acquired will help to translate innovations and proof-of-concept to realities.

Composite solid-state electrolytes are viewed as promising materials for solid-state lithium-ion batteries due to their combined advantages of inorganic solid-state electrolytes and solid-state polymer electrolytes. In this study, the solid electrolytes Li6.7−xLa3Zr1.7−xSb0.3NbxO12 (LLZSNO) with Sb and Nb co-doping were prepared by a high-temperature solid-phase method. Results indicate that Sb/Nb co-doping causes lattice deformation in LLZO and increases the lithium vacancy concentration and conductivity of LLZO. Then, with the co-doped LLZSNO as an inorganic filler, a composite solid electrolyte of polyvinylidene fluoride-hexafluoropropylene (PVDF-HFP) was prepared with a casting method. The obtained composite solid electrolyte exhibits a high ionic conductivity of 1.76 × 10−4 S/cm at room temperature, a wide electrochemical stable window of 5.2 V, and a lithium-ion transfer number of 0.32. The Li|LiFePO4 coin battery with the composite solid electrolyte shows a high specific capacity of 161.2 mAh/g and a Coulombic efficiency close to 100% at 1 C. In addition, the symmetrical lithium battery Li|Li with the composite electrolyte could cycle stably for about 1500 h without failure at room temperature. Full article

The diaphragm is a key component of the lithium-ion battery and largely determines its performance. Currently, commercial diaphragms suffer from poor thermal stability, low porosity, and low liquid absorption rate. In this study, we prepared a polyurethane/polyacrylonitrile (PU/PAN) lithium-ion battery diaphragm using a centrifugal spinning method with PU as the main substrate and PAN as the additive. The results showed that the PU/PAN nanofiber diaphragm prepared by centrifugal spinning had a 3D porous structure, and when using 18% PU:PAN = 7:3, the porosity of the fiber diaphragm was 83.9%, the liquid absorption rate was 493%, and the ionic conductivity was 1.79 mS/cm. The battery system had good electrochemical performance and thermal stability, with an electrochemical stability window of 5.2 V. The diaphragm did not shrink when heated at 160 °C. In a lithium-ion battery system with lithium iron phosphate (LiFePO4) as the cathode material, the capacity remained at 147.1 mAh/g after 50 cycles at a 0.2 C rate, with a capacity retention rate of 95.8%. This indicated excellent cycle stability and a multiplicative performance with good application potential. Full article
