In this video I explain how we made the Cement Battery and the chemicals used to dope it. We have done some things different in the way we made the copper electrode. The materials we used are:
Portland Cement 85%
Tin Oxide 2%
Zinc sulphide 2%
The Battery after drying all night in a controlled Magnetic oven
is holding at 1.5 volts at over 100Ma continuous current. When the battery
depletes it self you just let it sit and it comes right back and runs the oscillator again.
