The Mack Institute asks

What will be the 2017 industry-wide average cost of Li-ion batteries used in battery-powered electric vehicles?

This question will be resolved using the Mack Institute's analysis for 2017, which will replicate an approach published in a 2015 Nature Climate Change study. In 2016, using a similar method, the Mack Institute found that the average price had declined to $282 per kWh (Mack Institute). Lowering the cost of battery packs through R&D investments, manufacturing improvements, and economies of scale is a major consideration for bringing down the price of battery-powered electric vehicles (BEVs) and making them more competitive with gasoline-fueled internal combustion engines (Bloomberg, The Guardian).
