The electric battery was invented in the year 1800. It has been 212 years, yet we can't produce a battery right now that can retain large amounts of electricity so that it can be put onto the grid during peak hours. We don't have a battery, at least it does not appear that we have a battery, that can provide vehicles with the ability to compete with internal combustion fossil fuel-powered cars.
What is the holdup here? Why is it that humankind has made so many incredible advances in transportation technology and personal computers, etc., but we don't appear to have made a corresponding progress in the electric battery?
