To meet the growing demand for high energy density and power density in Li-ion batteries (LIBs) for electric vehicle (EV) applications (particularly in EVs offering a long driving range of 400–700 miles), production of lower cost, higher energy density cells is critically needed.
Battery density refers to the measure of energy stored in a battery relative to its weight or size. We refer to this as specific energy density, while in terms of size, it is known as volumetric energy density. So what exactly does this all mean? It’s important to understand the fundamental differences between lithium and lead-acid batteries.
In principle, however, science and industry agree that an increase in energy density can be achieved with solid-state batteries. It only remains to be seen whether this will be as high as the industry promises. The power density of a battery indicates the charging current with which a battery can be charged.
