Batteries are better because of all those improvements. >In fact, gains in the amount of energy [lithium-ion batteries] can store have been on the order of five percent per year. That means that the capacity of your current batteries is over 1.5 times what they would have held a decade ago… A study may identify a way to significantly improve one characteristic, generating an exciting top-line conclusion. But the design may be impractically poor in some other way. While battery researchers learn from what does and doesn’t work, this means that a lot of laboratory batteries you may read about will never hit the market…A recent study noted that “the real price of lithium-ion cells, scaled by their energy capacity, has declined by about 97 percent since their commercial introduction in 1991.” The early lithium-ion cells in the 1990s were around $3,000 per kilowatt-hour. By the early 2000s, that was nearer to $500 per kilowatt-hour.[1] [1] https://arstechnica.com/science/2021/05/eternally-five-years-away-no-batteries-are-improving-under-your-nose/ https://arstechnica.com/science/2021/05/eternally-five-years...
