The power generation principle of fruit battery is: in the experiment, the activity of two metal sheets is different, and the metal sheet with greater activity reacts with acidic substances in fruit to generate hydrogen ions. Because of the charge, the whole system needs to be stable (or an electric field is generated, which leads to the following results. ), so in the case of forming a primary battery, electrons keep the system stable from the loop, so theoretically, the current is directly related to the concentration of fruit acid. (If it is to be expressed as a function, then this function is actually related to the ionic strength, and it is also a quantitative relationship, and it is related to the qualitative ion concentration. ), in this case, if the length of the loop changes, it will inevitably cause the change of the loop, so it will also cause the change of the voltage.
Liquid ions have higher concentration and are easier to conduct electricity.
For example, lithium metal is used as a negative electrode, and a mixed solution of hydrochloric acid and sulfuric acid is used as an electrolyte.
The underground miner's lamp uses sulfuric acid.
This is a patent for liquid power generation equipment. Take a look.
