自制模板（通常是气泡和碳颗粒）的方法已被用来获得微米和纳米尺度的空心球。以LiOH·H2O、V2 O 5、H3 PO 4和N2 H4·H2O为原料，在250 °C水热反应48 h，制备了α-LiVOPO 4空心球。在该过程中，反应物V2 O 5颗粒充当模板，并且在水热反应完成时被消耗而没有任何残留物。因此，这种自我牺牲模板法使得大规模生产α-LiVOPO 4空心球成为可能。将α-LiVOPO 4空心球作为锂离子电池的正极和负极材料。
Self-produced template (usually bubbles and carbon particles) methods have been adopted to obtain micrometer- and nanometer-scaled hollow spheres. In this paper, we report the preparation of α-LiVOPO4 hollow spheres through a hydrothermal reaction of LiOH·H2O, V2O5, H3PO4, and N2H4·H2O at 250 °C for 48 h. During this procedure the reactant, V2O5 particles, served as the template and was consumed without any residues when the hydrothermal reaction was completed. Therefore, such a self-sacrifice template method makes large-scale production of α-LiVOPO4 hollow spheres feasible. α-LiVOPO4 hollow spheres were exploited as both cathode and anode materials for lithium ion batteries.
