The decline in Li-Ion battery pack prices has been impressive. Using BNEF data, pack-prices were ~$1100 / kWh back around 2010, and are currently sitting at $139 / kWh as of 2023. Despite the dramatic nature of the performance improvements, I have seen very few papers which holistically describe how this transformation occurred, even fewer from the key manufacturers (LG, Samsung, Panasonic, Tesla, BYD, CATL, SK One, etc.) that dominate the market. Of course, I'm sure some of the decline came from changes to the cell design itself, with higher energy density and substitution away from expensive materials, while some came from improvements to the manufacturing process. Both are of interest to me!
With that in mind, would love some insight from people here as to what happened! Bonus points for people with industry experience!
