The ranks of batteries aiming to challenge the dominant lithium ion technology have been swelling rapidly in the past few years are researchers and businesses seek a better and cheaper alternative to lithium ion technology. But lithium ion battery makers have not been sitting on their hands, either. According to BloombergNEF, the energy density of lithium ion battery dells has tripled over the last ten years. “Battery energy densities keep getting better. They’ve almost tripled at the cell level since 2010,” BloombergNEF’s Head of Advanced Transport, Colin McKerracher, said as quoted by CleanTechnica. What this means is that the new batteries can pack more energy in the same space than did the batteries from 2010. And they have not gotten more expensive for the increased density. On the contrary, EV battery pack costs have fallen from as much as $1,100 per kWh ten years ago to just $156 per […]
