Energy storage lithium battery type

Energy storage lithium battery type

The types of energy storage lithium batteries mainly include the following:
Lithium iron phosphate battery:
Lithium iron phosphate battery has excellent performance in the field of energy storage due to its high stability, long cycle life and low cost.
It is usually used in various links of the power system, such as generation, transmission and distribution.The energy density is about 120~150 wh/kg, the system energy conversion efficiency is 85%~88%, and the low-rate charge and discharge cycle life can reach 3500~5000 times.

Lithium cobalt oxide battery:
Lithium cobalt oxide battery has attracted attention due to its high energy density, but due to the scarcity of metal cobalt, its cost is high, and its cycle life and safety are poor, so it is rarely used in the energy storage field.

Lithium manganese oxide battery:
The energy density of lithium manganese oxide battery is similar to that of lithium iron phosphate battery, and its price is low, but due to its low service life, its full life cycle cost per kilowatt-hour is higher than that of lithium iron phosphate battery, so it is rarely used.
Ternary lithium battery:
Ternary lithium battery has extremely high energy density and a service life of up to 8-10 years, but its safety is relatively poor and its cost is higher than that of lithium iron phosphate battery. Therefore, its application prospects are weak in the field of energy storage that does not require extremely high energy density.

Sodium-ion batteries:
Sodium-ion batteries have cost advantages in large-scale energy storage applications due to their low cost and similar principles to lithium batteries.
Although they are similar to lithium batteries in technology and equipment, their cost is sufficient to support the continued development of electrochemical energy storage due to the abundant reserves of sodium resources.
These types of energy storage lithium batteries each have their own characteristics and applicable scenarios. Choosing the right type of energy storage lithium battery is crucial to improving the performance and economy of energy storage systems.
