wherein A represents an alkali cation and P and R each represent a multivalent transition metal cation;
wherein 0.5<z<1; and
wherein x, y, and z are related based on electrical neutrality, x>0, y>0, z>0; and
wherein n=6*(1−z)+mk, with n>0, with k=0 to 4 identifying a set of states for said electrodes, and with 6*(1−z) identifying as a quantity of coordinated water of said compound material, and with each mk>0, each mk identifying as a quantity of interstitial water of said compound material for one of said states of said electrodes, with each said quantity mk of interstitial water being equivalent to a weight percentage Mk=mk*WH2O/Wdry*100%, with WH2O being the molecular weight of water and Wdry being the molecular weight of the composition of conforming to formula I excluding all of its water content, with M0 identifying as an as-synthesized set of properties for said electrodes, with M1 identifying as a pre-assembly set of properties for said anode electrode, with M2 identifying as a pre-assembly set of properties for said cathode electrode, with M3 identifying as a post-communication set of properties for said anode electrode, and with M4 identifying as a post-communication set of properties for said cathode electrode; and
wherein said liquid electrolyte includes a polar organic solvent combined with an alkali metal salt and water having a water concentration, said water concentration including a pre-communication water concentration c1 and including a post-communication water concentration c2 and wherein c1>c2;
wherein said as-synthesized set of properties includes M0 up to 45% for formula I materials;
wherein said M1 includes a value less than 12% for materials including said composition conforming to formula I of said anode electrode with M1M3;
