Reversing global warming can be done swiftly by replacing activities which emit CO2 or harmful fumes and particles with activities that utilize electricity from a renewable source.
Many of such activities are carried out by portable devices.
Most of these devices are efficient only when they have a rechargeable battery which has high energy density and capable of fast on-boarding and discharging while maintaining 80 percent of capacity for more than 10000 cycles.
Let us develop and produce at a large scale batteries which exceed 1 kWh per kg , 4 C rate, 5 figure cycles and cost 100 USD per kg or less.
