Colloidal silver may have been tested as an electrolyte for dry cells, and maybe it hasn't. It certainly increases the conductivity of water and is very eco-friendly. The +charged silver ions suspended in the water may be attracted to the -charged side of the plates. They may clump there. This might reduce the production of O. Then again, the -charged silver ions may react completely different from my swag (sloppy wild azzed guess). Perhaps someone could try colloidal silver in a dry cell. Would sure revolutionize the dry cell if it works. Maybe some feedback, please? Thanks.
