This will be from improving processes going to the Tesla-Maxwell dry cell technology and with improved energy density and increasing the volume and other manufacturing efficiencies.
The global automotive lithium-ion battery market could reach about $95-100 billion per year by 2030.
A Cleantechnica analysis of the Tesla Cybertruck seems to show an implied 45% improvement in battery prices to about $100-110 per kwh by 2021.
$94 per kwh is the pricing expected in 2024 by Bloomberg New Energy Finance analysis.
InsideEVs performed a cost analysis of the new Tesla Maxwell dry cell technology which estimated a 20% improvement in battery pricing. This analysis did not take into account the lighter cars and price improvements from higher energy density from the new Maxwell batteries. Maxwell batteries should have about 30% higher energy density initially at about 385 watts per kilogram and could get another 30% when they increase to 500 watts per kilogram.
