Preparation method of Ti2Nb10O29 powder
The invention provides a method for preparing titanium niobate (Ti2Nb10O29, called TNO for short) powder, and belongs to the technical field of ceramic powder preparation. The preparation method comprises the following steps: heating (Ti0. 2Nb0. 8) C micron powder serving as a raw material to 800-1300 DEG C in an air atmosphere at a heating rate of 2-10 DEG C/min by adopting a one-step calcination method, oxidizing for 1-5 hours, and cooling to room temperature along with a furnace to obtain the TNO powder. According to the method, the preparation process is simplified, and the production efficiency is improved. A high-performance negative electrode material is provided for a lithium ion battery, and challenges in the aspects of high-rate charging and discharging, high safety and long-period stability are effectively solved.
本发明提供了一种制备钛铌酸盐（Ti2Nb10O29，简称TNO）粉体的方法，属陶瓷粉体制备技术领域。本发明使用(Ti0.2Nb0.8)C微米粉体作为原料，采用一步煅烧法，在空气氛围中以2~10 ℃/min的升温速率加热至800~1300 ℃，氧化1~5小时后，随炉冷却至室温，得到TNO粉体。该方法简化了制备流程，提高了生产效率。为锂离子电池提供了一种高性能的负极材料，有效解决了在高倍率充放电、高安全性和长周期稳定性方面的挑战。
