过渡金属／偏磷酸阳极活性材料、制备彼等之方法、及包含阳极活性材料之锂二次电池或混合式电容器;TRANSITION METAL-METAPHOSPHATE ANODE ACTIVE MATERIAL, METHOD OF PREPARING THE SAME, AND LITHIUM SECONDARY BATTERY OR HYBRID CAPACITOR INCLUDING THE ANODE ACTIVE MATERIAL

摘要

本发明提供阳极活性材料，其包含如化学式1之过渡金属/偏磷酸盐：<化学式1>M(PO3)2;其中M是选自由下列所组成的组群中的任一者：钛(Ti)、铬(Cr)、锰(Mn)、铁(Fe)、钴(Co)、镍(Ni)、钌(Ru)、钯(Pd)、与银(Ag)、或彼等之二或多种元素。;由于本发明之阳极活性材料稳定且具有出色的转化反应性并且只包含过渡金属与磷酸盐而不使用价格不断上涨的锂，本发明之阳极活性材料可改良容量特性。;Chemical Formula 1> M(PO3)2 where M is any one selected from the group consisting of titanium (Ti), chromium (Cr), manganese (Mn), iron (Fe), cobalt (Co), nickel (Ni), ruthenium (Ru), palladium (Pd), and silver (Ag), or two or more elements thereof. ;Since the anode active material of the present invention is stable and has excellent conversion reactivity while including only transition metal and phosphate without using lithium in which the price thereof is continuously increased, the anode active material of the present invention may improve capacity characteristics.
