    Some minor changes here and there, but the underlying makeup of the batteries and their shortcomings have been largely the same. Lithium and issues with dendrites that cause them to go bad/lose capacity after around 2,500 complete charge cycles. Most of the improvements have consisted of pulse charging different cells at a time in large batteries and trying to always keep the batteries in the 30% to 80% capacity range to extend the lifespan. Batteries last longer if you put one big enough in a vehicle to go 400 miles, but only allow for a 200 mile range.
