1. A method manufacturing an electrically conductive structure for an electrochemical cell, comprising the steps of:
a) providing an electrochemically active material including an agglomerated TMCCC;
b) providing a conductive material; and
c) binding said electrochemically active material to said conductive material producing a hierarchical structure, and wherein said hierarchical structure includes a plurality of primary crystallites having a size D1, and in which said plurality of primary crystallites are agglomerated into a set of agglomerates each agglomerate having a size D2>D1;
wherein said agglomerated TMCCC includes:
a composition of
LxMyNz Tia1Va2Cra3Mna4Fea5COa6Nia7Cua8Zna9Caa10Mga11[R(CN)6]b(H2O)c; and
a plurality of particles of said composition; and
wherein said plurality of particles include a hierarchical structure, and
wherein said hierarchical structure includes a plurality of primary crystallites having a size D1, and in which said plurality of primary crystallites are agglomerated into a set of agglomerates each agglomerate having a size D2>D1;
wherein each of L, M and N represents an alkaline metal;
wherein each of P, Q, and R represents a metal cation optionally including one or more of Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ca, Mg, and the like;
wherein 0≤x≤2;
wherein 0≤y≤x;
wherein 0≤z≤x;
wherein 0<b≤1;
wherein 0<c;
wherein for each element of the set {a1, a2, a3, a4, a5, a6, a7, a8, a9, a10, a11}, 0≤{a1, a2, a3, a4, a5, a6, a7, a8, a9, a10, a11}≤1; and
wherein at least one of {a1, a2, a3, a4, a5, a6, a7, a8, a9, a10, a11} is >0.
