What is the role of lithium-ion batteries? Use English translation?

Usually, the cathode (cathode) is made of lithium cobalt oxide and the anode (anode) is made of graphite.

Positive and negative electrodes are concepts in primary batteries. Positive and negative here refer to the positive and negative of the potential: the one with a positive potential is the positive electrode, where the original reaction occurs and where the electrons are found. obtained; the one with a negative potential is the negative electrode, where oxidation, the loss of electrons, occurs.

Anode and cathode are concepts in an electrolytic cell. Yin and yang here refer to the oxidation or reduction reaction : the anode is the oxidation reaction and the cathode is the reduction reaction.

Detailed information:

< p>Lithium cobalt oxide is the first generation of commercial cathode material. It has been gradually modified and improved over decades of development and can be considered the most mature cathode material for lithium-ion batteries. Lithium cobalt oxide has the advantages of high discharge platform, high specific capacity, good cycle performance and simple synthesis process. However, this material contains more cobalt and costs more.

Lithium cobalt oxide remains the best choice for small lithium batteries. Currently, in 3C electronic batteries, most still use lithium cobalt oxide instead of ternary materials with specific capacity plus high. The reason is that the compacted density of lithium cobalt oxide materials is higher than that of ternary materials, that is, lithium cobalt oxide which. can be accommodated per unit volume. Among small batteries that pay more attention to volume density, lithium cobalt oxide occupies a place.

Lithium cobalt oxide has a high theoretical capacity, but its actual capacity is only half of the theoretical capacity. The reason is that lithium ions are released from the lithium cobalt oxide material during the charging process, but when the released amount is less than 50%, the morphology and crystal shape of the material can remain stable.

As the amount of released lithium ions increases up to 50%, the lithium cobalt oxide material will undergo a phase change. If charging continues at this time, the cobalt will dissolve in the electrolyte and gewill generate oxygen, seriously affecting the operation of the electrolyte. battery cycle. Stability and safety performance, so the general lithium cobalt oxide charging cut-off voltage is 4.2V.

Now the lithium battery is classified by LIB (liquefied lithium ion battery) and PLB. (Polymer-lithium battery). Here, LIB refers to the secondary battery consisting of an inserted lithium-ion compound which forms the positive and negative poles Th. The positive pole consists of LiCoO2 or LiMn2O2. The negative pole is made of the LixC6 lithium battery and is capable of providing high voltage and power. In addition, it does not cause pollution or memory effect. discharge, but long life. Therefore, it would be the ideal power source of the 21st century.

In 1992, Sony successfully exploited the lithium battery. Its practice has greatly reduced the weight and size of cell phones and computers.portable devices. and portable electrical devices extending their lifespan. Since the lithium battery does not contain any heavy metals, this significantly minimizes environmental pollution, compared to the nickel-chromium battery.
