While battery innovation appears gradual, the incremental leaps add up over time. Battery innovation is improving around 5 to 8 percent per year, which can deliver a doubling in core performance metrics every ten years, which is ultimately really “revolutionary” said [Tesla’s CTO and co-founder J.B.] Straubel. Because of the large size and heavy physical weight of batteries involved with electric cars, the impact of battery innovation on the design of the car can be even more significant than Moore’s Law has on some computing products, added Straubel.
For car design, “It’s almost as if the properties of steel were improving at a rate of 5 to 8 percent per year,” said Straubel.
… the energy density of batteries goes up 15 percent every 18 months; the cost per kilowatt hour goes down 15 percent every 18 months; the life cycles of the batteries (how many times it can charge and recharge) goes up 15 percent every 18 months; and the cost per lifecycle-mile does down 50 percent every 18 months.
