Specific energy is how much energy is in a given amount of something. It's sometimes referred to as energy density, which is a bit more self-explanatory but technically refers to volume, not mass.

Energy density is the main property of rechargeable batteries that has driven the entire technology forward in past decades. Lithium-ion batteries (LIBs) now surpass other, previously competitive ...

When the anode has a high volumetric energy density, it tends to hold more energy, which is influenced by tapped density. An ideal tapped density for spherical graphite in anode manufacturing is ...
