Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a new lithium metal battery that can be charged and discharged at least 6,000 times — more than any other pouch battery cell — and can be recharged in a matter of minutes.
I would love to see more dramatic research into battery tech, but steps like this are also welcome, as these are necessary stepping stones before even better steps.
A breakthrough often enables more than just a marginal improvement in theory. However building real world, mass produceable products based on the science is not an instant process, and very commonly manifest as a trickle rather than all at once.
LED lighting has changed the world, when they first came out in 1962 as faint ir emitting devices, they were quite useless for most of the purposes we know them for today.
