Advantages and Disadvantages Of Ternary Lithium Battery

Many people say that the lithium iron phosphate battery should be fully charged, and the ternary lithium battery should be charged to more than 90%. The reason is that the voltage of the lithium battery will increase after it is fully charged, which will affect the activity of the electrolyte and positive and negative materials, resulting in battery capacity attenuation. . At the same time, the ternary lithium battery is not suitable for over-discharging, and it is best to charge it when the power is left at 30%.

The advantages of ternary lithium battery:

1. The energy density per unit volume is higher than that of lithium iron phosphate batteries, and the energy density is the same as that of lithium iron phosphate batteries. The volume of ternary lithium batteries is smaller, and the same size of ternary lithium batteries can provide higher battery life.

2. The cyclic charge and discharge performance of the ternary lithium battery is better. Under normal circumstances, it can be charged and discharged more than 2000 times.

Coupled with the high energy density of the ternary lithium battery, the charging frequency will be relatively lower, in other words, the service life will be longer.

3.The ternary lithium battery is not afraid of cold, and the battery life in winter is not as bad as the lithium iron phosphate battery.The reaction between the active lithium of the ternary lithium battery and the lithium ion battery electrolyte will release heat, so the disadvantage of this battery is that it is easy to generate heat. However, as long as you don't apply too much charging current, and there is a cooling system on the battery, the heat released by the reaction will not pose too much threat.

The increasing charging power of fast charging will cause the battery to generate heat much faster than it dissipates heat.High temperature will cause lithium ions to precipitate out too quickly to form dendrite-like crystals, which will pierce the lithium battery separator between the positive and negative electrodes to form a short circuit.
