What is the difference between a primary battery and an electrolytic cell

A primary battery is a very official term. In fact, a device that generates current through an oxidation-reduction reaction is called a primary battery, which can also be said to be a device that converts chemical energy into electrical energy. Here is a popular science, batteries basically convert chemical energy into electrical energy. So the batteries you can see basically belong to the category of primary batteries. Such as nickel-metal hydride batteries, polymer batteries, etc. Electrolytic cell The electrolytic cell is just the opposite of the primary battery, which is a device that converts electrical energy into chemical energy. Very useful for metal protection. The difference between the primary battery and the electrolytic cell 1. The essential difference between the electrolytic cell and the primary battery The essential difference The electrolytic cell converts electrical energy into chemical energy, and the primary battery converts chemical energy into electrical energy. 2. The electrolytic cell itself must have an external power source to be used, and the original battery can be supplied normally without an external power source. 3. The electron flow direction of the electrolyte and the primary battery are different. The flow direction of the primary battery is opposite to the direction of the current (the current is positive and the electrons are negatively charged); and the electrolytic cell is the opposite of the primary battery (the electrons flow out into the electrolytic cell through the negative electrode). 4. The application of primary batteries is generally on batteries, while electrolytic cells are generally used in electroplating, refining, metallurgy and other industries. 5. There is generally no distinction between positive and negative electrodes for electrolytic cells, and they are generally called cathodes and anodes, while primary batteries are the familiar distinction between positive and negative electrodes.
