2. Electrochemical reactions
Like all electrochemical generators, a battery, also known as a primary generator or non-rechargeable generator, has several regions or zones:
a cathodic region, site of a global reduction reaction (positive pole);
an anodic region, site of a global oxidation reaction (negative pole);
a separator region, which physically separates the two electrodes and eliminates any risk of short-circuits. This region must be porous to accommodate the electrolyte solution;
an electrolyte solution which soaks the three above-mentioned regions, and which is necessary for the operation of the battery through the ionic exchanges it enables.
The electrolyte solution corresponds to a volume distributed over the three regions...
