Types of Lithium-Ion Batteries and their Energy Density. Lithium-ion batteries are often lumped together as a group of batteries that all contain lithium, but their chemical composition can vary widely and with differing performance as a result. Most lithium-ion battery types share a similar design of a cathode with aluminum backing, a carbon or graphite anode with copper backing,
The higher the volumetric energy density is, the smaller the battery pack can be (assuming the same energy content). It's not the only metric, as there is also the gravimetric energy density, which tells how much energy can be stored per weight unit. The higher it is, the lighter the battery pack can be.
