这个早就有新闻了,特斯拉现在用4680电池不是看重能量密度,是看重制造成本。“A Model Y's 4680 pack, for instance, is US$3,600 cheaper to manufacture than one with 2170 cells, but even then Tesla is only halfway through with the cost reduction potential of the new technology. It has yet to master and scale the dry-coating cathode method which would bring the pack's cost down US$5,500 compared to the 2170 battery.” 实际上4680电池的能量密度是可以提上去,但是成本就不同了。
