Suppose the main power source is 12 V and the battery 9 V. Then the 12 V source will drop, say, 0.5 V (Schottky diode), so the voltage at the cathode will be 11.5 V, which is higher than the battery''s 9 V, so that diode won''t conduct current. When the main source is off the battery will supply power via its diode.
