Increasing energy density is about increasing the amount of energy stored in a given volume and is a priority for battery manufacturers. This would increase the range of an electric vehicle without physically increasing the size of the battery pack, or allow automakers to install smaller units without sacrificing range.

Panasonic plans to improve energy density with a new blend of additives that will allow individual battery cells in a battery to operate at higher voltages without detrimental effects.

The company plans to achieve its goal "within a few years", but has not said when it will start producing battery cells with the new additives. If a 20% increase in energy density is achieved, it is likely to be 900 watt-hours per liter (Wh/L) compared to 750 Wh/L for Panasonic's most advanced battery pack.
