    摘要： The present invention relates to a process for the preparation of a mixture for producing lithium titanium spinel Li4Ti5O12, having the step of mixing Li2CO3 and TiO2 in a vessel (1) in which at least one oblong element (2) with a first end (2a) and a second end (2b) is arranged such that the first end (2a) points towards an inner wall (1a) of the vessel (1) and is at a distance d from same, wherein the mixing step is carried out by allowing the vessel (1) to rotate and holding the oblong element (2) in its position, with the result that a relative movement takes place between the inner wall (1a) of the vessel (1) and the first end (2a) of the oblong element (2), wherein the distance d is kept constant during mixing. In addition, the invention relates to a process for the preparation of lithium titanium spinel Li4Ti5O12 from a thus-obtained mixture and its use as anode material in rechargeable lithium-ion batteries.

    摘要翻译： 本发明涉及一种制备锂钛尖晶石Li4Ti5O12的混合物的制备方法，该混合物具有在容器（1）中混合Li 2 CO 3和TiO 2的步骤，其中至少一个具有第一端（2a）的长方形元件 ），并且第二端（2b）布置成使得第一端（2a）指向容器（1）的内壁（1a）并且距离其距离d，其中混合步骤通过允许 容器（1）将长方形元件（2）旋转并保持在其位置，结果是在容器（1）的内壁（1a）和第一端（2a）之间发生相对运动 椭圆形元件（2），其中距离d在混合期间保持恒定。 另外，本发明涉及从这样得到的混合物制备锂钛尖晶石Li 4 Ti 5 O 12的方法，其用作可再充电锂离子电池中的负极材料。
