67% energy density increase on the previous Leaf cells seem like a huge claim to substantiate...../In Japan specification, which is all that has been revealed so far, buyers will benefit from a huge leap in driving range, courtesy of an extra-dense new 40kWh lithium-ion battery pack.
That design is packed into the same space allocated to the previous model’s battery pack – initially a 24kWh, later upgraded to 30kWh.
“It’s the individual cell structure of the laminated lithium-ion battery cells that’s been improved, representing an impressive 67% increase in energy density versus the 2010 model,” Nissan says.
“Another key engineering improvement for the lithium-ion battery pack is enhanced electrode materials with revised chemistry, resulting in higher power density while contributing to greater battery durability upon charge and discharge.”
I guess they will have traded off some of the previous cells 10-15C discharge capability in order to improve Ah capacity. ?
