Unlocking the Potential of Na2Ti3O7-C Hollow Microspheres in Sodium-Ion Batteries via Template-Free Synthesis
Published on 2025-03-10 by Yong-Gang Sun, Yu Hu, Li Dong, Ting-Ting Zhou, Xiang-Yu Qian, Fa-Jia Zhang, Jia-Qi Shen, Zhi-Yang Shan, Li-Ping Yang, Xi-Jie Lin @MDPI
Abstract: Layered sodium trititanate (Na2Ti3O7) is a promising anode material for sodium-ion batteries due to its suitable charge/discharge plateaus, cost-effectiveness, and eco-friendliness. However, its slow Na+ diffusion kinetics, poor electron conductivity, and instability during cycling pose significant challenges for practical applications. To address these issues, we developed a template-free method to synthesize Na2Ti3O7-C hollow microspheres. The synthesis began with polymerization-induced colloi[...]
Our summary: Unlocking potential of Na2Ti3O7-C hollow microspheres in sodium-ion batteries through template-free synthesis, enhancing cycling performance and rate capability, new strategy for high-performance anodes.
