The cumulative cost benefits thus f

The cumulative cost benefits thus far of these new cathode and anode materials can perhaps be summarized in the modeled cost of productions by the US Department of Energy (DOE), Vehicle Technologies Office. Over a 7-year span, the modelled cost has decreased ≈70% to ≈268 US$ kWh−1 (2015).[212] While there are still a large volume of estimates from literature that ranges from 1700 to 1000 US$ (YR:2014) as summarized by Nykvist in Figure 13a, there were a number of corroborating optimistic estimates claiming ≈220–400 US$ (YR:2014) kWh−1 (Figure 13b)[209] and 250 US$ kWh−1 in 2015.[55]
