✦ Synopsis

Ahstrac-The msemon of sodmm m manganese dloxlde electrodes from 1M NaClO,-PC solution was observed It starts at 2 8 V and IS completed at 2 2 V (agamst Na reference electrode) The dlffuslon coefficient D = 5 x lo-l4 cm* s-l was estimated Lmutmg concentration is lower than that for lithmm, which 1s explained as accommodation of sodmm m broader tunnels m y-MnO, lattice, whde hthnnn enters both kmds of tunnels
