Lithium battery manufacturers' depiction of shell characteristics.CR2032 battery

　　First, lithium, atomic order 3, atomic weight 6.941, is a very light alkaline metal raw material. In order to improve security and voltage, scientists invented the use of graphite and lithium cobaltate to store lithium atoms. The molecular structure of these data forms a fine storage grid of nano -level, which can be used to store lithium atoms. In this way, even if the battery shell breaks and oxygen enters, it will be too large because the oxygen molecules cannot enter these subtle storage compartments, so that the lithium atom will not touch the oxygen to avoid blasting.

　　2. Protection measures taken by the battery

　　After the lithium battery core is charged to the voltage of 4.2V, it will start to produce side effects. The higher the voltage, the higher the risk. After the voltage of the lithium battery is higher than 4.2V, the number of lithium atoms in the positive data is less than half. At this moment, the storage lattice will often fall, causing the battery capacity to cause a permanent decline. If you continue to charge, because the negative storage lattice is already full of lithium atoms, subsequent lithium metal will accumulate on the appearance of negative material materials. These lithium atoms grow from the direction of negative surfaces to lithium ions. These lithium metal crystals will pass through the diaphragm paper to make the positive and negative short circuit.

　　Therefore, when the lithium battery is charged, the voltage limit must be set to take into account the life, capacity, and security of the battery together. The ideal charging voltage limit is 4.2V. There must be a lower limit when the lithium battery is discharged. When the battery voltage is lower than 2.4V, some data began to be destroyed.
