...the University of Southampton (UK) and REAPsystems have found in a research, that a new type of battery could improve the efficiency of solar power...
.. Storage costs shall be reduced as well...
student Yue Wu wrote:"the research showed that the lithium battery has an energy efficiency of 95 per cent whereas the lead-acid batteries commonly used today only have around 80 per cent. The weight of the lithium batteries is lower and they have a longer life span than the lead-acid batteries reaching up to 1,600 charge/discharge cycles, meaning they would need to be replaced less frequently."
