This pioneering battery exhibited higher energy density value up to 130 Wh kg −1 (gravimetric) and 280 Wh L −1 (volumetric). The Table 1 illustrates the energy densities of initial rechargeable LIBs introduced commercially, accompanied by the respective company names .
An energy storage device or battery can have high specific energy (Wh/kg) but poor specific power (W/kg), as is the case with hydrogen cells, for example, or low specific energy but high specific power, as with a supercapacitor (ultracapacitor). Power density is the amount of power (time rate of energy transfer) per unit volume.
Power density is the amount of power (time rate of energy transfer) per unit volume. For energy conversions, including batteries, fuel cells, motors, power supply units, etc., power density refers to a volume, where it is often referred to as volume power density and is expressed in W/m³ or W/L.
The specific power, or gravimetric power density, indicates the charging capacity. Power tool batteries are designed for high specific power and are supplied with reduced specific energy (capacity). Figure 1 illustrates the relationship between specific energy (water in the bottle) and specific power (spout).
Specific energy, or gravimetric energy density, defines battery capacity in weight (Wh/kg); energy density, or volumetric energy density, reflects volume in liters (Wh/l). Products requiring long runtimes at moderate load are optimized for high specific energy; the ability to deliver high current loads can be ignored.
The energy density of LIBs is crucial among the issues including safety, capacity, and longevity that need to be addressed more efficiently to satisfy the consumer’s demand in the EV market. Elevated energy density is a prime concern in the case of increasing driving range and reducing battery pack size.

Energy density vs power density
Energy density is the amount of energy in a given mass (or volume) and power density is the amount of power in a given mass. The distinction between the two is similar to the difference between Energy and power. Batteries have a higher energy density than capacitors, but a capacitor has a higher power density than a battery.This difference comes from batteries being …
