All figures are typical ranges, not a substitute for a specific cell datasheet — they vary by manufacturer, cell format and C-rate.
What the data means: LTO’s position in the chemistry family is set by two numbers working against each other — energy density (Wh/kg) and cycle life. LTO sits at roughly 50–80 Wh/kg and 10,000–20,000 cycles, which places it at a specific point on the energy-versus-longevity trade-off.
Why it matters: A datasheet number only means something with its basis — cell-level energy density is not pack-level, and cycle life is only meaningful at a stated depth of discharge and temperature. Read LTO against those conditions, never as a bare figure.
