Battery Cell Ragone Plot

Battery cell ragone plot is power density vs energy density. A plot often used to compare chemistry.

This plot needs to consider peak versus continuous power. The following plot is from the Cell Database.

In this plot we can just about see a trend that higher energy density => lower power density. Although with a mix of cell chemistry and cells from 1991 to present this is blurred to some extent.
