mah kg a third test was also conducted two cells were assembled each having a pbo 2 cathode a zinc anode and an electrolyte comprising emihso 4 pva these two cells which as shown above each separately provide about 1 80 volts were linked in series and found to create a 3 6 v 10 ma power source sufficient to power a relatively large led while not considered necessary to enablement of the current invention the electrochemical half cell reactions are as follows with m representing manganese or lead m 4 o u2212 2 2 2hso 4 u2212 2 e u2212 u2192 m 2 oh u2212 2 2so 4 u2212 2 zn 0 so 4 u2212 2 u2192 zn 2 so 4 u2212 2 2 e u2212 m 4 o u2212 2 2 2hso 4 u2212 2zn 0 u2192 m 2 oh u2212 2 2zn 2 so 4 u2212 2 2 e u2212 the various cells described above were constructed as follows a liquid cell was created using a zinc strip as the anode the cathode was made by coating a gold metal strip with a thin polymer coating the coating being composed of about 70 wt mno 2 about.
