OverviewRechargeable configurationsHistoryThermal batteries (non-rechargeable)See alsoExternal links
Since the mid-1960s much development work has been undertaken on rechargeable batteries using sodium (Na) for the negative electrodes. Sodium is attractive because of its high reduction potential of −2.71 volts, low weight, relative abundance, and low cost. In order to construct practical batteries, the sodium must be in liquid form. The melting point of sodium is 98 °C (208 °F). T…
