People haven't understood how lithium batteries worked at a molecular level... until now

It turns out that radical chemistry works in such a way that ethylene carbonate (the "magic" electrolyte, see the post), which is reduced on graphite electrode, can polymerize yielding a 3D cross-linked polymer network, like a net, whereas propylene carbonate makes a disconnected network, like a bowl of spaghetti, so electrolyte molecules keep diffusing through it and intercalating between graphene sheets, eventually destroying the electrode.

That's science for "MAGIC".
