New Battery Could Mean More-Efficient Solar Energy Storage

New Battery Could Mean More-Efficient Solar Energy Storage

Working in tandem, the University of Southampton and lithium battery technology company REAPsystems have discovered that a new type of battery has the potential to increase the efficiency and reduce the cost of solar power . The study looked specifically at the use of lithium batteries as a storage method for solar power in photovoltaic systems and found that they were a more efficient method than the lead acid batteries currently used in most systems. “Lead acid batteries are traditionally the energy storage device used for most photovoltaic systems,” said lead researcher Yue Wu, a MSc Sustainable Energy Technologies student. “However, as an energy storage device, lithium batteries, especially the LiFePO4 batteries we used, have more favourable characteristics.” Data for their research was acquired by connecting a lithium iron phosphate battery to a photovoltaic system at...
