The principals of electrochemical power have been known for more than 200 years. Two specific chemicals are stored in a battery, separated by a third chemical called an “electrolyte.” When placed in a closed circuit (the device needing power), one of the chemicals reacts with the electrolyte and produces a higher concentration of electrons at the negative terminal, the “anode,” than at the positive terminal, the “cathode.” The electrons then run from the anode, through the device powering it, to the cathode, until the concentration …
