energy density of 175 Wh/kg
CATL explained that sodium-ion batteries have slightly lower energy density than lithium-ion batteries but provide distinct advantages in low-temperature performance, carbon footprint, and safety.
How much energy you get out of a full charge, divided by how much energy you need to fully charge it. It’s around the 90% mark for lithium based tech, no idea what it is for these sodium ones
