What are the important differences between batteries and lithium-ion batteries?

What is the difference between a battery and a lithium-ion battery? Lithium-ion battery is a type of battery. Its purpose is to store a limited amount of electricity and use it in an appropriate place. Its working principle is to convert chemical energy into electrical energy. The lead plate filled with spongy lead is used as the negative electrode, the lead plate filled with lead dioxide is used as the positive electrode, and 22-28% dilute sulfuric acid is used as the electrolyte. Electric energy is converted into chemical energy when charging, and chemical energy is converted into electric energy when discharging. When the battery is discharged, the metallic lead is the negative electrode and is oxidized to lead sulfate. Lead dioxide is a positive electrode, which is reduced to lead sulfate. When the battery is charged with direct current, lead and lead dioxide will appear at the two poles. When the power supply is removed, it will return to the pre-discharged state, forming a chemical battery. Lead batteries are batteries that can be repeatedly charged and discharged, called secondary batteries. Its voltage is 2V, usually when three lead batteries are connected in series, the voltage is 6V. This car uses a 12V battery pack with six lead batteries connected in series. After the battery is used for a period of time, sulfuric acid should be added to keep the electrolyte containing 22-28% dilute sulfuric acid. Lithium-ion batteries are batteries made with lithium metal or lithium alloy as the positive electrode material and using non-aqueous electrolyte solutions. The first lithium-ion battery came from the great inventor Thomas Edison. Due to the very active chemical properties of metal lithium, the processing, storage and use of metal lithium have very high requirements on the environment. Therefore, lithium-ion batteries have not been used for a long time. With the development of microelectronics technology in the 20th century, the degree of miniaturization of equipment is increasing. Lithium-ion batteries then entered the stage of large-scale practical use. It was originally used in pacemakers. Since the self-discharge rate of lithium-ion batteries is very low, the discharge voltage is relatively mild. It makes it possible for a pacemaker to be implanted in the body for long-term use. The nominal voltage of lithium-ion batteries usually exceeds 3.0 volts, so they are more suitable for integrated circuit power supplies. Manganese dioxide batteries are widely used in computers, calculators, cameras and watches. Disclaimer: Some pictures and content of the articles published on this site are from the Internet.
