The Institute of Electrical and Electronics Engineers (IEEE) Spectrum
Magazine
featured an article three weeks ago that included a chart
based on work by Micah Ziegler Jessika Trancik and at the
Massachusetts Institute of Technology.
It showed the dramatic drop in lithium-ion battery costs over the past three
decades (chart attached below) :-

Batteries today, the researchers say, have mass-production scales and energy densities unthinkable 30 years ago. Economies of scale and technological improvements appear set to drive storage costs further, approaching the USD100 per kilowatt-hour threshold. At about that level, the energy costs for EVs will reach parity with those for gasoline-powered vehicles, according to Bloomberg New Energy Finance.

Like the dramatic drop in the price of computers over decades, early
adopters paid a premium.

Engineers and energy-policy planners benefit from knowing future battery prices, but unlike solar prices, they aren’t always readily available. Lithium-ion batteries tend to be manufactured or bought in bulk by large companies. “Those contracts aren’t necessarily public documents,” says Ziegler. That’s partly why the drivers for the price decline are, for Ziegler and Trancik, an open area of research.

Based on current trends in the chart, by 2030, it may well transpire
that those still with ICE vehicles rather than EV's will be viewed as
those who have money to burn.
