Will Supercapacitors Come to AI's Rescue?

Cars That Think

electricity provider National Grid faces a problem every time there is a soccer match on (or any other widely viewed televised event for that matter): During half-time, or a commercial break, an inordinate number of viewers go to turn on their tea kettles. These and other such products can help smooth out load fluctuations on the grid.

IHS Markit: average cost of lithium-ion battery cell to fall below $100/kWh in 2023

Green Car Congress

The average cost of a Li-ion battery cell—used to power electric vehicles and to provide flexibility in the power grid as more renewables, such as solar and wind, are added will fall below $100 per kilowatt hour (kWh) in the next three years, according to a new analysis by IHS Markit. Cost is the name of the game.
