Boffins Create Printed Battery

Where would you use such a battery if you got your hands on one?

the first place i would think of is to power small displays in phones etc

Fantastic technology that, the applications for small and light devices like watches and stuff could be endless

1.5V of power, power is measured in watts though?

 

[FarFarAway]

Wattage is the voltage multiplied by current (amps). Seeing as voltage is the standard theoretical output of a battery (at idle), they are measured in volts. Think this is right, but I'm sure someone better at physics can correct me if not

 

[Jeddy]

A batteries nominal voltage or potential difference is the voltage given out when there is no load on the battery. The voltage given out by the battery when loaded is lower than the potential difference because the resistance of the battery itself creates a minor voltage divider with any other resistance in the circuit.

Thus the "power" of 1.5v is not really correct. The higher the current draw the lower the voltage given out by the battery. So basically the "power" of 1.5v isnt really a correct peice of information.
