The average cost of a Li-ion battery cell—used to power electric vehicles and to provide flexibility in the power grid as more renewables, such as solar and wind, are added will fall below $100 per kilowatt hour (kWh) in the next three years, according to a new analysis by IHS Markit.

decade, have projected 2020 costs for fully installed 100 MW, 10-hour battery systems of: lithium-ion LFP ($356/kWh), lead-acid ($356/kWh), lithium-ion NMC ($366/kWh), and vanadium RFB ($399/kWh). For lithium-ion and lead-acid technologies at this scale, the direct current (DC) storage block accounts for nearly 40% of the total installed costs. ll ',6&/$,0(5 7klv grfxphqw zdv suhsduhg dv dq dffrxqw ri zrun vsrqvruhg e\ wkh 8qlwhg 6wdwhv *ryhuqphqw :kloh wklv grfxphqw lv eholhyhg wr frqwdlq fruuhfw lqirupdwlrq qhlwkhu wkh 8qlwhg 6wdwhv *ryhuqphqw qru dq\ djhqf\ wkhuhri qru 7kh 5hjhqwv ri wkh 8qlyhuvlw\ ri

Let’s assume one full charge/discharge cycle per day at a total capacity of 1.2 kWh per cycle. Using the above information, we can determine that the battery will be able to store/release a total of 5760 kWh over a 10-year period. Therefore, the LCOS for this battery will be 0.05 $/kWh.

Based on quoted transportation costs for 8,000 tonnes cells (still in battery packs, Figure S3 A), shipping from the UK collection point to South Korea and China amounts to 1.24 $·kWh −1, to Belgium and the UK 0.39 $·kWh −1, and to the US 1.55 $·kWh −1. The contribution of transportation to the total recycling cost is 7–13% for China
RedT Energy Storage (2018) and Uhrig et al. (2016) both state that the costs of a vanadium redox flow battery system are approximately $ 490/kWh and $ 400/kWh, respectively [ 89, 90 ]. Aquino et al. (2017a) estimated the price at a higher value of between $ 730/kWh and $ 1200/kWh when including PCS cost and a $ 131/kWh performance guarantee
