Reply to comment by RandomlyMethodical in NASA has invented a new type of high-performance battery that researchers claim could be used to power fully electric airplanes. by phife_is_a_dawg

It'd be fun to see a chart tracking the progress of Wh/kg over time, to visually see how much we're improving year to year.

Though come to think of it, that would be measured as Wh/kg per year, and if we simplified that, would it mean that battery progress of this type can be measured in W/kg?

Suppose you had a magical 1kg battery which constantly upgrades its capacity to match the state of the art battery tech. The W/kg figure would be the amount of power you have to continuously pump into that battery to keep it fully charged (ignoring self-discharge). I approve of this unit.

Everything can be simplified if you are willing to ignore the complexities 😭😩
