Hey guys,
Currently I am trying to build a low tech super capacitor based on the working the principle. Right now I am using a single beaker with two aluminium foil positive and negative electrodes with an electrolyte of 6M NaCl solution. The power source is a new-ish triple-A battery running at 1.4 volts. What happens is gas evolves on the electrodes. How do I keep this from happening? I understand that I must change the electrolyte but for what reason? Also will charge be able to be stored on the electrodes with a voltage below 1.23v using the current electrolyte? Thanks and appreciate any input.
