Sodium and magnesium batteries with intercalation electrodes are currently alternatives of great interest to lithium in stationary applications, such as distribution networks or renewable energies. Hydrated laminar oxides such as birnessites are an attractive cathode material for these batteries. Sodium and potassium birnessite samples have been synthesized by thermal and hydrothermal oxidation methods. Hybrid electrochemical cells have been built using potassium birnessite in aqueous sodium electrolyte, when starting in discharge and with a capacity slightly higher than 70 mA h g−1. Hydrothermal synthesis generally shows slightly poorer electrochemical behavior than their thermal counterparts in both sodium and potassium batteries. The study on hybrid electrolytes has resulted in the successful galvanostatic cycling of both sodium birnessite and potassium birnessite in aqueous magnesium electrolyte, with maximum capacities of 85 and 50 mA h g−1, respectively.

Dihydrogen Orthophosphate

The osmotic coefficients of aqueous NaH2PO4 and aqueous KH2PO4 over the ranges 1.0-6.5 mol kg-1 for the sodium salt and 0.85-2.2 mol kg-1 for the potassium salt were determined at 25�C by the isopiestic method. Our data were combined with the data of Scatchard and Breckenridge for low concentrations in order to calculate smooth values of osmotic and activity coefficients for concentrations down to 0.1 mol kg-1.
