So, that appears to be an evolution from the high power, but lower voltage Lithium Titanate batteries.
This should make a lightweight high-power hybrid brake power regaining system possible.
My Insights 27 kg NiMH battery can only absorb about 10 kW under braking. That feels like coasting, especially at higher speeds. Too often I need to brake harder, like 'normal', wasting the momentum into heat and brake dust.
Yet, as a battery it falls short a bit as 14 Wh per kilo is way less than the 100-265 Wh/kg
Wikipedia attributes to regular Li-Ion batteries.
A mixed pack though could be a winner.
