Energy density of EV batteries triples in 10 years
A report by BNEF highlights that the energy density of NCM811 cells has now reached 300Wh/kg, treble the 100Wh/kg level that LMO cells were able to reach in 2010. At the same time battery pack prices have fallen 87% to reach US$135/kWh (from US$1183/kWh). However the easy gains are likely to have ended. 300Wh/kg is pretty close to the maximum theoretical capacity for lithium-ion batteries which means that further increases in energy density are not overly likely. Raw material costs are pretty much rock bottom, which means that the only possible grounds for further price reduction would likely be from...
