Abstract
lnsertion of sodium into phosphates Na3M2(P O4% (M = Fe, V) were investigated electrochemically to determine the usefulness as the possible cathodes for sodium batteries. The discharge curves show that sodium ion can be accommodated into these hosts. Specific charges of up to 45 mAhgi and 140 mAhgi were obtained for NatNa3Fg(P O4ts and Na/Na3V2(P O4b oells with liquid organic el ectrolytes at room temperature, respectively. lntercalat ion processes under constant current densities of O.1 mA㎝’2 were reversible within the range of composition 3.0<xく3.4 for Na.Fe,(PO4ts and 1.2 〈 x 〈 3.8 for Na.V2(P O4)3.
