Systems, methods and articles of manufacture for surface-modified transition metal cyanide coordination compound (TMCCC) compositions; improved electrodes comprising the compositions; and methods of making the compositions. The composition, compound, device and its use, A x Mn (y-k ) M j k [Mn m (CN) (6-p-q) (NC) p (Che) r q] z. (Che) r w (Vac) (1-z) . Associated with nH 2 O. In the formula, Vac is a vacancy of Mn (CN) (6-pq) (NC) p (Che) r q . Che is an acid chelator. A is Na, K, Li; M is Mg, Al, Ca, Sc, Ti, V, Cr, Fe, Co, Ni, Cu, Zn, Ga, Pd, Ag, Cd, In, Sn, Pb It is. 0 <j ≦ 4; 0 ≦ k ≦ 0.1; 0 ≦ (p + q) <6; 0 <x ≦ 4; 0 ≦ y ≦ 1; 0 <z ≦ 1 Yes; 0 <w ≦ 0.2; 0 <n ≦ 6; −3 ≦ r ≦ 3. x + 2 (y−k) + jk + (m + (r + 1) q−6) z + wr = 0. |
