Brief description of the working principle of lithium battery and future development prospect

The working principle of lithium battery Lithium battery is a kind of rechargeable battery, which depends on the movement of lithium ions between the positive electrode and the negative electrode to work. During the charging and discharging process, Li+ intercalates and deintercalates back and forth between the two electrodes: when recharging the battery, Li+ deintercalates from the positive electrode and inserts into the negative electrode through the electrolyte, and the negative electrode is in a lithium-rich state; the opposite is true during discharge. Batteries that generally use materials containing lithium as electrodes are representative of modern high-performance batteries. The charging and discharging process of lithium batteries is the process of intercalation and deintercalation of lithium ions. In the process of intercalation and deintercalation of lithium ions, it is accompanied by the intercalation and deintercalation of electrons equivalent to that of lithium ions (the positive electrode is usually represented by insertion or deintercalation, and the negative electrode is represented by insertion or deintercalation). In the process of charging and discharging, lithium ions are inserted/de-intercalated and inserted/de-intercalated back and forth between the positive and negative electrodes, which is vividly called the rocking chair battery. When charging a lithium battery, lithium ions are generated on the positive electrode of the battery, and the generated lithium ions move to the negative electrode through the electrolyte. The carbon as the negative electrode has a layered structure. It has many micropores. The lithium ions reaching the negative electrode are inserted into the micropores of the carbon layer. The more lithium ions are inserted, the higher the charging capacity. The future development prospects of lithium batteries Lithium batteries, its use range and proportion are constantly changing. In the future, the focus of use should be concentrated in electric tools, new energy vehicles, light electric vehicles, energy storage systems, and so on. The scale of industries in these areas should maintain a multiplied upward trend in the next few years. Energy storage technology is a strategic support for future energy structure transformation and power processing and consumption changes. Driven by the development and commercialization of energy storage technology, power lithium batteries, as one of the protagonists of the new energy industry, will also usher in new opportunities for development. The large-scale development of energy storage will promote the extension and integration of the lithium battery industry chain, and promote the connection of the upper, middle and lower reaches of the power lithium battery industry with capital, synchronize with the market, and achieve win-win cooperation. Lithium batteries are widely used in energy storage power systems such as water power, thermal power, wind power and solar power stations, uninterrupted power supplies for post and telecommunications, as well as power tools, electric bicycles, electric motorcycles, electric vehicles, military equipment, aerospace and many other fields.
