According to the Bloomberg New Energy Finance, who surveyed more than 50 companies, lithium-ion battery prices are today cheaper than ever.

The indicatedcurrent price stands at $209 per kWh, on the pack level.

The price provided by BNEF is 24% lower than one given a year ago, and just about a fifth of what it was in 2010.

But the good news doesn't end there. It's expected that by 2025 battery prices will decrease below $100 per kWh on the pack level.

That should enable the selling of plug-in electric vehicles without a premium, but still with all the benefits of cheap energy to drive.

"That’s a magic number for the electric car business. According to BNEF analyst James Frith, $100 is widely seen as “a tipping point in the adoption of EVs.”

"The price estimates are based on a BNEF survey of more than 50 companies, and their decline reflects a rise in battery manufacturing and “the economies of scale that come with it,” the report shows. Developers of stationary storage systems -- like the kind that back up rooftop solar panels -- can expect to pay 51 percent more than automakers because of much lower order volumes."
