  Explain the technical knowledge of lithium-ion batteries

  1. What is a lithium battery A lithium battery is the battery we use in our mobile phones or electric cars. 英文: Li's more professional explanation is a kind of metal lithium or lithium alloy as the positive electrode material, using non-hydrolytic solution, which can be reused

  1. What is a lithium-ion battery

  Lithium-ion batteries are the ones we use in our mobile phones or electric cars. Chinese: Li

  A more professional explanation is a rechargeable battery that uses lithium metal or lithium alloy as the positive electrode material and uses a non-hydrolytic solution.

  Lithium-ion batteries can be roughly divided into two categories: lithium-ion batteries and lithium metal batteries. We use a lot of lithium-ion batteries, and then we start to see lithium metal batteries are safer, more powerful, and more cost-effective. Li-ion batteries do not contain lithium metal and are rechargeable. The lithium-ion battery mentioned in this article mainly refers to the lithium-ion battery.

  Lithium-ion batteries are mainly composed of two parts: the battery and the management system (a simple management system is also called a protection board). The battery is the heart of the lithium-ion battery, and the battery management system is the brain of the lithium-ion battery.

  Battery, BMS (Battery Management System), PCM (Protection Circuit Module)

  Lithium-ion batteries must use a proper battery management system, otherwise they are very dangerous. A Li-ion battery with a Li-ion battery management system is often referred to as a Li-Pack.

  2. What is Li-ion battery

  Power lithium-ion battery battery is a kind of power, which refers to the application of the storage battery on the electric power transmission system. It is related to the consumption of lithium-ion batteries, such as electric vehicles, lithium-ion batteries, lithium-ion batteries for electric bicycles, electric tools, bicycle The lithium-ion battery of the self-balancing car, the lithium-ion battery is more extensive and sometimes the lithium-ion battery power lithium battery for energy storage.

  Compared with ordinary lithium-ion batteries, power lithium-ion batteries generally have more special requirements, such as high energy density, high volume-to-energy ratio, wide temperature range, high-power discharge support, longer cycle life and safer.

  3. Structure of Li-ion battery

  Lithium-ion batteries are mainly composed of four parts: positive electrode material, negative electrode material, electrolyte, and thin film.

  The lithium-ion battery pack is mainly composed of two parts: the battery and the battery management system.

  4. Working principle of lithium-ion battery

  Lithium-ion batteries are lithium ions that are repeatedly intercalated between the positive electrode and the negative electrode to realize the charging and discharging of the battery. It is actually a redox reaction.

  The principle of the charging process is as follows (as opposed to the discharging process):

  Positive electrode: LiCoO2→Li(1-x)CoO2+(x)Li++(x)e-

  Negative: C+(x)Li++(x)e-→CLi(x)

  Battery reaction: LiCoO2+C→Li(1-x)CoO2+CLi(x)

  5. Advantages and disadvantages of lithium-ion batteries

  The advantages and disadvantages of lithium-ion batteries and other batteries such as lead-acid batteries, nickel-cadmium batteries, and nickel-metal hydride batteries are compared.

  Lithium-ion batteries have the advantages of high voltage, high energy density (light weight, small size), long service life, and environmental protection.

  The disadvantage of lithium-ion batteries is that the price is relatively high, the temperature range is relatively narrow, and there are certain safety risks (to add a protection system).
