"All of a sudden, we can put a metal platform under a perovskite, utterly changing the interaction of the electrons within the perovskite. Thus, we use a physical method to engineer that interaction." This illustration from the Guo Lab shows the interaction between a perovskite material (cyan) and a substrate of metal-dielectric material.
it''s not really charge limiting that is absent. if the battery was really overcharged, it would most likely explode; the internal battery management system (which is probably the same as in a phone) avoids this. its the fact that the battery is not cycled at all in desktop-like scenarios that is the problem. some manufacturers have a setting in the bios that protects against this, e.g. https …
One of the most transformative changes in technology over the last few decades has been the massive drop in the cost of clean energy.

There are exactly two reasons why LiFePO4 batteries are getting cheaper. (A) The first reason is that they do not contain rare elements like cobalt so there is no supply chain bottleneck to restrain supply. (B) The second reason is the actual mechanism of the price reduction: expiring patents. Now, for the details about (B). . .
