Батареї покращуються не так швидко як хотілося б, але все ж таки в півтора-два ради кожні 10 років
If you look, the data bears out a number of trends. Energy density has a prominent trend. The original commercial lithium-ion battery, produced by Sony in the early 1990s, had an energy density of under 100 watt-hours per kilogram. That number has climbed over time, with the familiar cylindrical 18650 cells on the market hitting 200 watt-hours per kilogram by 2010. According to BloombergNEF, batteries used in electric vehicles have gotten as high as 300 watt-hours per kilogram in the last couple of years.
That has been easy to see if you’ve followed EVs at all, as the early options had nowhere near the range of what we see today. The first Tesla Model S offered about 210 miles of range, while it can now be purchased with up to 390 miles. The first Nissan Leaf could go about 75 miles, while a 2020 model can go 225 miles.
