Dalhousie researchers find low-voltage NMC532 cells have higher energy density than LFP, very long lifetime

Green Car Congress

Researchers led by Professor Jeff Dahn at Dalhousie University in Canada report that low-voltage NMC cells—particularly those balanced and charged to 3.8V —show better coulombic efficiency, less capacity fade and higher energy density compared to LFP cells and are projected to yield lifetimes approaching a century at 25 °C.
