What are primary batteries and electrolytic cells? What are the differences between them

A device that generates an electric current through an oxidation-reduction reaction is called a galvanic battery, which can also be said to be a device that converts chemical energy into electrical energy. Some primary batteries can constitute reversible batteries, and some primary batteries are not reversible batteries. When the primary battery is discharged, the negative electrode undergoes an oxidation reaction, and the positive electrode undergoes a reduction reaction. For example, the copper-zinc primary battery is also known as the Danner battery. The positive electrode is a copper electrode and is immersed in a copper sulfate solution; the negative electrode is a zinc plate and is immersed in a zinc sulfate solution. The two electrolyte solutions are connected by a salt bridge, and the two poles are connected by wires to form a galvanic cell. The dry batteries used in daily life are made according to the principle of primary batteries. The important application of the electrolytic cell is used in the industrial production of high-purity metals. It is a device that converts electrical energy into chemical energy (composition: external power supply, electrolyte solution, anode and cathode). The process in which current passes through the electrolyte solution or molten electrolyte to cause reduction and oxidation reactions at the anode and the anode. The process of passing current through an electrolyte solution or molten electrolyte to cause a reduction and oxidation reaction on the anode and cathode is called electrolysis. The device that converts electrical energy into chemical energy is called an electrolytic cell or an electrolytic cell. When ions reach the electrode, they lose or gain electrons, and the process of redox reaction occurs. Electrolysis principle. It consumes electricity. The difference between the primary battery and the electrolytic cell 1. The essential difference between the electrolytic cell and the primary battery: the electrolytic cell converts electrical energy into chemical energy; the primary battery converts chemical energy into electrical energy. 2. The difference between the electrolytic cell and the primary battery device: the electrolytic cell has an external power source; the primary battery does not have an external power source. 3. The difference between the electron flow direction of the electrolytic cell and the galvanic battery: the electron flow of the galvanic cell is just opposite to the direction of the current (the current is positive and the electrons are negatively charged); the electrolytic cell is just the opposite of the electron flow of the galvanic battery (the electrons flow out through the negative electrode to In the electrolytic cell). 4. The application difference between electrolytic cell and primary cell: primary cell is used in storage battery; electrolytic cell is used in electroplating, refining and metallurgy. 5. The difference between the electrolytic cell and the primary battery level: the electrolytic cell is called the anode and cathode; the primary battery is called the anode and cathode. 6. The difference between the electricity of the electrolytic cell and the primary battery: the primary battery is for external power supply, which is spontaneous; the electrolytic cell is to be energized, which is passive.
