Do you know the Application of Lithium Iron Phosphate Batteries in Photovoltaic Power Generation?

Apr. 21, 2020

As a LiFePO4 Battery Wholesale, share with you. High-performance energy storage batteries are essential to the development of the photovoltaic industry. Compared with lead-acid batteries, LiFePO4 Battery has the advantages of high specific energy, high energy storage efficiency, long cycle life and low use cost. Using this type of lithium battery as an energy storage device can increase energy efficiency to about 90%, so it is very suitable for use as a new energy storage device. The lead-acid batteries and lithium iron phosphate batteries are compared in terms of conventional performance and energy storage characteristics. Based on the analysis of the feasibility of using lithium iron phosphate batteries as energy storage devices in photovoltaic systems, the corresponding photovoltaic energy storage systems are designed.

Among the many renewable energy sources, solar energy has become the most potential energy form with its green, environmental protection, inexhaustible and inexhaustible characteristics, and has huge market prospects. China has very rich solar energy resources, and the development of the photovoltaic industry is of great significance to the improvement of electricity consumption in China's underdeveloped and remote areas. However, photovoltaic power generation has discontinuity and instability, and the power generation performance changes with changes in the external environment. Therefore, high-performance power storage links are crucial to the development of the photovoltaic industry.

Lithium iron phosphate battery is a new secondary power source developed in recent years. It has the characteristics of large input and output power, wide operating temperature range, no memory effect, maintenance-free, 2,000 charge and discharge service life, safety and green environmental protection. Is becoming the protagonist of chemical batteries.

The main material of the lithium iron phosphate battery is carbon, and the main material of the positive electrode is lithium iron phosphate LiFePO4. The electrolyte uses LiPF6 organic solvent. The basic principle of charge and discharge is the insertion and extraction of lithium ions between the positive and negative electrodes.

The voltage platform of the lithium iron phosphate battery is 3.2V, and the specific energy is more than twice that of the lead-acid battery, while the volume specific energy is 4 to 5 times that of the lead-acid battery. The system can greatly reduce the space occupied by the battery and reduce the maintenance workload.
