Tesla’s Maxwell Dry Battery and a Five Year Lead on the World:
"Tesla bought Maxwell Technologies for their dry battery technology. Maxwell proved 300
Wh/kg energy density is which 20-40% better than current Tesla batteries. Maxwell has
a path with 15-25% improvement every 2-3 years. This should lead to 500 Wh/kg by
2027. This would give Tesla a 5 year battery lead on the rest of the world."
