Lithium aluminate (LiAlO₂) has been successfully synthesized by a hydrothermal reaction based on using the anodic alumina (AAO) as the template and explored as the compound materials in LiMnPO₄/C lithium battery. LiAlO₂ nanoplate porous structure is inherited from anodic aluminum oxide (AAO) structure and serves as substrates to grow LiMnPO₄ nanocrystals, which provide a high surface area with a porous structure. The morphology, structure, and electrochemical properties of the samples were analyzed. The instruments used in this process are X-ray diffraction (XRD), scanning electron microscopy (SEM), high-resolution transmission electron microscope (HRTEM), and charge-discharge test system. The crystallization transition process of the precursor after hydrothermal reaction was researched by thermal gravity analysis. The specific surface area and pore volume of LiAlO₂ are 118.6 m²/g and 0.89 cm³/g, which were confirmed by the method of nitrogen adsorption. Moreover, the 10% content LiAlO₂-LiMnPO₄/C has the excellent electrochemical performance, and its first discharge capacity is 144 mAh/g at 0.1 C, compared with the LiMnPO₄/C electrode (121 mAh/g at 0.1 C). The LiAlO₂ can obstruct the direct contact of electrode and electrolyte, thus reducing their direct contact areas of cathode at charged state, owing to the fact that LiAlO₂ around the active surfaces of LiMnPO₄ grains acts as an ionic conductive wiring.

以阳极氧化铝（AAO）为模板，通过水热反应成功合成了铝酸锂（LiAlO ₂），并作为LiMnPO ₄ / C锂电池的复合材料进行了探索。LiAlO ₂纳米板多孔结构继承自阳极氧化铝（AAO）结构，并用作生长LiMnPO _4的基质纳米晶体，可提供具有多孔结构的高表面积。分析了样品的形态，结构和电化学性能。此过程中使用的仪器是X射线衍射（XRD），扫描电子显微镜（SEM），高分辨率透射电子显微镜（HRTEM）和充放电测试系统。通过热重分析研究了水热反应后前驱体的结晶转变过程。比表面积和LiAlO的细孔容积₂是118.6米² / g且0.89厘米³ /克，这是由氮吸附的方法确认。另外，LiAlO ₂ -LiMnPO ₄为10％。/ C具有出色的电化学性能，与LiMnPO ₄ / C电极（0.1 C下为121 mAh / g）相比，其在0.1 C下的首次放电容量为144 mAh / g 。LiAlO ₂可以阻碍电极和电解质的直接接触，从而由于在LiMnPO ₄晶粒的活性表面周围的LiAlO ₂充当离子导电线路这一事实而减小了它们在充电状态下阴极的直接接触面积。
