The method comprises: mixing the raw materials, pressing for shaping, reacting at high temperatures, and cooling the product to obtain magnesium aluminate spinel material.

其制备方法为：以铝型材厂污泥和碱式碳酸镁为主原料，将原料混合压制成型，经高温反应，反应产物经冷却，得到制备的镁铝尖晶石材料。

The current model of the Volt uses lithium-ion batteries made with lithium-manganese spinel cathodes ("spinel" refers to the three-dimensional arrangement of atoms in the material).

通用汽车的风险投资部门总裁乔恩Lauckner说：提高能源密度的整个概念涉及到车辆的种类奖项时他表示，目前还不清楚多少钱，新技术将保存，但“我只想说，这是非常重要，它不 是一该电压电流模型使用的锂锰尖晶石阴极制成的锂离子电池(“尖晶石"指的是三维的原子排列)。
