Battery energy density is the amount of energy a battery contains compared to its weight or size. We call this the specific energy density when comparing to weight and volumetric energy density when comparing size. For example, we measure a battery’s energy in watt-hours (watts per hour, the equivalent of using one wattfor one hour).
If the energy density of a battery is too high, it could present a safety issue. When there’s more active material packed into a cell, it increases the risk of a thermal event. Which Type of Rechargeable Battery Has the Highest Energy Density?
A battery with high energy density has a longer battery run time in relation to the battery size. Alternately, a battery with high energy density can deliver the same amount of energy, but in a smaller footprint compared to a battery with lower energy density. This greatly expands the possibilities for battery applications.
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.
Batteries with high energy density have transformed the mobile world. With more energy, we can fit useful batteries in smaller spaces. This enables long-lasting phones, laptops, earbuds, or medical devices. They’re also very lightweight compared to past alternatives. Could you imagine carrying around a 5 lb iPhone? Or a 10 lb tablet?
We can then divide a battery’s watt hours (wh) by its kilograms (weight) or volume (liters). Therefore, the length of time a battery can power a device compared to its weight or size equals the energy density. Why Does Battery Energy Density Matter?
