Introduction to the working principle of the primary battery

The device that generates current through the oxidation-reduction reaction is called a galvanic battery, which is a battery device that converts chemical energy into electrical energy. Its working principle is very simple. Generally, people who have studied chemistry can quickly understand this principle. The oxidation-reduction reaction of the primary battery is an exothermic reaction. The general redox reaction is completed by effective collision between the oxidant and the reducing agent to complete the electron transfer. The reaction of the primary battery is different. What is the reaction of the primary battery? The working principle of the primary battery is that the reducing agent loses electrons on the negative electrode to cause an oxidation reaction, and the electrons are transported to the positive electrode through an external circuit, and the oxidant obtains electrons on the positive electrode to undergo a reduction reaction, thereby completing the electron transfer between the reducing agent and the oxidizing agent. The directional movement of the ions in the solution between the two electrodes and the directional movement of the electrons in the external wire form a closed loop, so that the two electrodes react continuously, an orderly electron transfer process occurs, and an electric current appears to realize the conversion of chemical energy to electric energy. Through the continuous transfer of electrons, voltage and current are formed, thus forming a galvanic battery.
