The embodiment of the invention relates to an active material, an electrode, a secondary battery, a battery pack, and a vehicle. The invention provides an active material and an electrode capable of realizing a high-capacity secondary battery, a high-capacity secondary battery and a battery pack, and a vehicle equipped with the battery pack. According to an embodiment, there is provided an active material including a composite oxide including a plurality of rhenium oxide-type blocks having different sizes, and the rhenium oxide-type blocks are shared by at least octahedral edges without having a periodically connected structure. The rhenium oxide-type block includes an octahedral structure composed of oxygen and a metal element, and is configured by sharing the apexes of the octahedral structure. The composite oxide is represented by a general formula LiaMbNbMocOd. Wherein M is at least one element selected from the group consisting of Ti, V, Ta, Fe, Co, Mn, Ni, Bi, Sb, As, P, Cr, W, B, Na, K, Mg, Al, Ca, Y, and Si, 0 < = a < = b + 2 + 3c, 0 < = b < = 1.5, 0 < = c < = 0.5, and 2.33 < = d/(1 + b + c) < = 2.50.

    本发明的实施方式涉及活性物质、电极、二次电池、电池包及车辆。提供能实现高容量的二次电池的活性物质及电极、高容量的二次电池及电池包、以及搭载有该电池包的车辆。根据实施方式,提供包含复合氧化物的活性物质,所述复合氧化物包含含有大小不同的多个氧化铼型块、并且该氧化铼型块至少通过八面体棱共有而不具有周期性地连接的结构。氧化铼型块包含由氧和金属元素构成的八面体结构、并且通过八面体结构的顶点共有而构成。复合氧化物以通式LiaMbNbMocOd表示。其中,M为选自由Ti、V、Ta、Fe、Co、Mn、Ni、Bi、Sb、As、P、Cr、W、B、Na、K、Mg、Al、Ca、Y及Si构成的组中的任一种以上,0≤a≤b+2+3c、0≤b≤1.5、0≤c≤0.5、及2.33≤d/(1+b+c)≤2.50。
