摘要：

The insertion of sodium in manganese dioxide electrodes from 1M NaClO4-PC solution was observed. It starts at 2.8 V and is completed at 2.2 V (against Na reference electrode). The diffusion coefficient D = 5 x 10(-14) cm2s-1 was estimated. Limiting concentration is lower than that for lithium, which is explained as accommodation of sodium in broader tunnels in gamma-MnO2 lattice, while lithium enters both kinds of tunnels.
