Hierachical structure of transition metal cyanide coordination compounds

A method manufacturing an electrically conductive structure for an electro chemical 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 LxMyNzTia1Va2Cra3Mna4Fea5Coa6Nia7Cua8Zna9Caa10Mga11[R(CN)6]b(H20)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 alkali metal;
• wherein R represents a metal cation 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;
