以水滑石为前驱体,采用微波辅助合成法,制备复合水滑石前驱体材料（CoAl-LDHs）,该前驱体是由超薄纳米片组成。经焙烧处理后,得到多孔纳米花球状Co3O4/Al2O3复合材料。研究结果表明,电极在0.2 A/g的电流密度下,经过100次循环之后仍能表现较好的稳定性且倍率性能良好,在为光伏电站配置锂离子电池储能系统的材料选择上提供可能。
Abstract
Using hydrotalcite as the precursor, the composite hydrotalcite precursor material （CoAl-LDHs） was prepared by microwave-assisted synthesis. The precursor was composed of ultra-thin nanosheets. The porous nano-flower spherical Co3O4/Al2O3 composite was obtained by calcining. The results show that the electrode can still perform well in stability and multiplier performance after 100 cycles at the current density of 0.2 A/g, which makes it possible to select materials for the configuration of lithium ion battery energy storage system for photovoltaic power stations.
