Given this, the lifetime energy affordability is 1447 Wh $ -1 ($0.69 kWh -1 ). This is about an order of magnitude higher than batteries from applications such as UAV, for comparison. If higher estimates of cycle life are chosen assuming partial DoD, a much higher lifetime energy affordability can be obtained . For the LTO chemistry, applications are generally limited to low driving range regions or larger vehicles such as electric buses; however, charge times can be reduced dramatically with the high specific power for charging (2530 W kg -1 ).
