If you’re in the market for a new battery or simply curious about the types of batteries available, you may have come across the term “energy density” before. Energy density is a measure of how much energy a battery can store per unit of weight or volume. The higher the energy density, the more power the battery can provide for its size.

The devices boast a gravimetric energy density of 711.3 Wh/kg and a volumetric energy density of 1653.65 Wh/L, both of which are the highest in rechargeable lithium batteries based on an intercalation-type cathode, Li tells Physics World.
As a result, the intercalation battery is more realistic to achieve high energy densities in the near term. Though enormous challenges remain, the conversion battery is the long-term pursuing target for high energy densities because it has a higher theoretical limit. 7.2. Reactions in primary batteries
The energy density of AA batteries varies depending on the type of battery. Alkaline AA batteries, which are the most common type of AA battery, have an energy density of around 100-150 Wh/kg. Lithium AA batteries, on the other hand, have a much higher energy density, with some models reaching up to 300 Wh/kg.
Safety is a primary requirement, but elevated energy density will increase the risks during battery operation, they say. “Energy density must be gradually improved while ensuring safety,” says Li. “Our goal is to enhance battery safety performance through solid-state battery technology, making high-energy density batteries more practical.”

Therefore, engineers aim to design batteries with the maximum amount of energy per unit mass (energy density) and the highest possible power output per unit area (power density). Various factors come into play in striking this balance, including the choice of battery chemistry, design of the battery''s internal structure, and the specific needs of the application.
The battery achieved a mass-energy density of 711.30 Wh/kg and a volumetric energy density of 1653.65 Wh/L during the initial discharge, making it the lithium secondary battery with the highest publicly reported energy density values so far.
High current density (6C) and high power density (>8000 W kg −1) are now achievable using fluorinated carbon nanofiber (CF 0.76) n as the cathode in batteries, with energy density of 1749 Wh kg −1 [65].
