The new lithium battery can increase the efficiency of photovoltaic system energy storage to about 95%

The University of Southampton in the United Kingdom (University of Southampton) and REAPsystems have discovered a new type of lithium battery that can be used as an energy storage device for photovoltaic systems. The energy storage efficiency can be increased to about 95%, which greatly reduces the cost of solar power generation.　　 Most of the current photovoltaic systems also use lead-acid batteries as energy storage devices, but in comparison, the replacement of lithium iron phosphate batteries can give full play to its advantages, including improving energy storage efficiency, extending service life, reducing unit costs, and so on. This type of lithium battery is used as an energy storage device, which can increase the energy efficiency to 95%, far exceeding 80% of the traditional lead-acid battery, and has a service life of more than 1600 times of charge and discharge.　　 The project is sponsored by REAPsystems and led by MSc student Yue Wu and his supervisor Dr. Carlos Poncede Leon, Professor Tom Markvart, and Dr. John Low. The project specifically studied the use of lithium batteries as energy storage devices for photovoltaic systems.　　 student Yue Wu said,'Lead-acid batteries are traditionally used in most photovoltaic systems as energy storage devices. However, as an energy storage device, lithium batteries, especially the LiFePO4 batteries we use, have more favorable characteristics. '　　 The collection of these data requires the connection of a lithium iron phosphate battery and a photovoltaic system. The photovoltaic system is installed on the university building and uses a specially designed battery management system provided by REAPsystems.　　 Yue added,'Research shows that this kind of lithium battery has 95% energy efficiency, while the current commonly used lead-acid battery is only about 80%. Lithium batteries are lighter in weight and have a longer service life than lead-acid batteries. The number of charge and discharge can reach 1600 cycles, which means that they do not need to be replaced frequently. '　　Although the battery needs further testing before it is put into commercial photovoltaic power generation system. But research has shown that LiFePO4 batteries are expected to increase the efficiency of solar power generation systems and help reduce their installation and maintenance costs. Dr. CarlosPoncedeLeon and Dr. JohnLow are planning to do further project research with a group of new students. Dr. Dennis Doerffel, the founder of REAPsystems and a former researcher at the University of Southampton, said: “For various energy sources (renewable or non-renewable), energy storage devices, such as batteries, play an important role in energy utilization, unlike traditional lead-acid batteries In comparison, LiFePO4 batteries have higher efficiency, longer service life, lighter weight and lower cost. We are expected to see this battery widely used in photovoltaic systems, as well as other renewable energy systems.
