Can Lithium Batteries Compete with Lead?

I was talking with a friend of mine who specifies battery technologies for a living. Our conversation drifted to the topic of electric vehicles and, more specifically, the batteries for them.

I suggested the idea that many times the good old lead acid battery is hard to beat for many applications, even ones with severe weight requirements because:

  • Joule for joule they are heavier than newer battery types include Lithium chemistry variants, but they are not an order of magnitude heavier
  • Most everyone knows how to deal with a lead acid battery
