High-capacity anode material for lithium secondary batteries and process for synthesizing the same
摘要：
The present invention features a high-capacity anode material for rapidly chargeable and dischargeable lithium secondary batteries, which is composed of Li4Ti5O12 nanoparticles. The Li4Ti5O12 nanoparticles of the present invention exhibit excellent crystallinity and high rate capability compared to those synthesized using a conventional polyol process or solid reaction process by converting Li4Ti5O12, which is a zero-strain insert material spotlighted as an anode active material for lithium secondary batteries, into Li4Ti5O12, having a high crystalline nanostructure using a solvothermal synthesis process without performing additional heat treatment. The present invention also features methods of, and a method of preparing the high-capacity anode materials described herein.
摘要（中）：

本发明的特征在于用于快速充电和放电的锂二次电池的高容量负极材料，其由Li 4 Ti 5 O 12纳米颗粒组成。 本发明的Li 4 Ti 5 O 12纳米颗粒与使用常规多元醇工艺或固体反应方法合成的Li4Ti5O12纳米颗粒相比，其表现出优异的结晶度和高的速率能力，该Li4Ti5O12是作为锂二次电池的负极活性材料聚焦的零应变插入材料， 进入具有高结晶纳米结构的Li 4 Ti 5 O 12中，使用溶剂热合成方法，而不进行额外的热处理。 本发明还涉及制备本文所述的大容量阳极材料的方法和方法。
