Recent research indicates that phosphorus and metal phosphides show great promise as anode candidates for sodium-ion batteries because of their low cost and relatively high theoretical gravimetric and volumetric specific capacities.
A vast number of materials for positive electrodes of sodium-ion batteries were proposed and investigated, including various layered oxides, phosphates, sulfates, fluorides, polyanion compounds, organic polymers, etc. [ 16 – 23 ]. Electrodes of these materials demonstrated the specific capacity values of up to 200 mA h/g.
White phosphorus is very toxic, volatile, and ignites spontaneously in air; thus, its practical application in sodium-ion batteries is impossible. Red phosphorus is sufficiently stable under normal conditions; and, hence, it is usually studied as the negative-electrode material.
By and large, the characteristics of electrodes for reversible intercalation of lithium are higher than the characteristics of their sodium analogues; however, as applied to lithium-ion batteries phosphorus does rank below silicon. For sodium-ion batteries, silicon is of no special interest as the material of negative electrodes.
