Abstract

This study focuses on the synthesis and performance optimization of novel electrode materials for lithium-ion batteries. By analyzing the structural stability, interfacial reactions, and electrochemical properties of both cathode and anode materials, various optimization strategies such as gradient doping, nanocomposite design, and interface engineering were proposed. Multiple electrochemical testing methods, including constant current charge–discharge, cyclic voltammetry, and electrochemical impedance spectroscopy, were employed to comprehensively assess the effects of these strategies on material performance. The results indicate that gradient-doped cathode materials exhibit enhanced thermal stability and reduced capacity decay under high-temperature and high-voltage conditions; the nanocomposite anode design effectively alleviates the volume expansion of silicon-based materials, significantly reducing the expansion rate and improving cycling stability; and interface engineering markedly decreases the charge transfer impedance, thereby boosting battery power output. Full-cell evaluations demonstrate that the novel electrode materials achieve an energy density of 235 Wh·kg⁻¹, while maintaining high cycle life even under extreme temperature conditions. Furthermore, the study systematically analyzes key issues related to industrial-scale production, material compatibility, and sustainable development, discussing the feasibility of process optimization and environmentally friendly technologies for large-scale applications. Overall, this research not only provides theoretical and experimental support for the development of high-performance lithium-ion battery electrodes but also outlines a clear pathway for industrialization and the advancement of a green, low-carbon economy.
