Analyze the development of lithium batteries

Lithium batteries are a kind of work that relies on the transfer between the anode and cathode of lithium ion rechargeable batteries to charge and discharge. When the battery, the movement of lithium ions is generated actively through the electrolyte anode, and the more the carbon layer of the lithium ion cathode is embedded, the more the battery capacity At the same time, when the battery is discharged, the positive movement of lithium ions on the cathode carbon layer, and the movement of lithium ions to the anode, the greater the flow, the greater the flow. Lithium batteries, commonly referred to as lithium batteries, are used in mobile phones and notebook computers. Lithium batteries are easily confused with lithium batteries. The important difference lies in the materials they use. Lithium battery is a kind of metal lithium as the negative electrode. Due to the huge danger of actual lithium battery, it is rarely used in daily electronic life products. The positive electrode of the lithium battery is manganese dioxide or thionyl chloride, and the negative electrode is lithium. During the charging and discharging cycle, lithium is easy to form crystals, leading to internal short circuits in the battery. After the battery is packaged, the battery will have voltage and does not need to be charged. The battery can also be recharged, but the cycle performance is poor. Early lithium batteries are generally not rechargeable. On the basis of lithium batteries, Sony invented a lithium battery with carbon material as the negative electrode and lithium-containing compound as the positive electrode. During charging and discharging, there is no metallic lithium, only lithium ions. This is a rechargeable lithium battery. Lithium batteries have the advantages of light weight, large capacity, and no memory effect, and can charge mobile phones at any time. Therefore, many digital devices today are powered by lithium batteries. Lithium batteries have a high energy density, their capacity is 1.5 to 2 times that of nickel-hydrogen batteries of the same weight, and the self-discharge rate is very low. In addition, lithium batteries have almost no memory effect and no toxic substances, which is an important reason why lithium batteries are widely used.
