The abundance and low cost of sulfur is appealing for Li-S in renewable energy applications as long as the cell-level affordability can be optimized to suitable levels. Given that affordability and cycle life are primary criterion for renewable energy applications , we make an analysis of a commercial lithium-titanate (LTO) battery. Altairnano TM produces a 70 Ah LTO battery that delivers 82 Wh kg - with discharge and charge powers of 1290 W kg -1 and 2530 W kg -1 , respectively, and lasts for 25,000+ cycles (until 80% of initial capacity) . A rough price estimate shows that an Altairnano 24 V 70 Ah LTO battery pack has an energy affordability and lifetime energy affordability of 0.435 Wh $ -1 ($2300 kWh -1 ) and 16697.25 Wh $ -1 ($0.06 kWh -1 ), respectively 1 . The long cycle life makes a large difference for lifetime energy affordability despite potentially larger upfront costs. In terms of investment, a high lifetime energy affordability results in a higher net present value (i.e. returns minus costs) of an energy storage solution for long-term applications. One of the biggest drawbacks of the LTO chemistry is the low specific energy and therefore greater mass associated with these batteries.
