What is the Energy Density of a Lithium-Ion Battery?
An LTO battery is one of the oldest types of lithium-ion batteries and has an energy density on the lower side as lithium-ion batteries go, around 50-80 Wh/kg. In these batteries, lithium titanate is used in the anode in place of carbon, which allows electrons to enter and exit the anode faster than in other types of lithium-ion batteries.
