The blending volume of negative density difference displacement is much less than that of the positivedensity difference displacement.
负密度差顶替时掺混量比正密度差顶替小。

The positive electrodes are often made from lithium iron phosphate. Corvus, however, USES lithium nickel manganese cobalt (NMC) because it provides a greater energy density.
锂电池的正极一般是用磷酸锂铁制作，而乌鸦公司却使用能量密度更好地镍钴锰酸锂来制作锂电池正极。
