Mystery of Lithium Ion Batteries Solved – Scientific American

Researchers discover how charge transfer works

••

In the push for batteries that store more energy and cost less, many researchers are chasing diminishing performance returns with exotic materials and chemistries, including lithium air, liquid metal and molten salt.

One of the problems is that scientists are still grappling with the fundamental physics behind batteries and are finding out that in some instances, they’ve been going about it all wrong.

Last week, in the journal Nature Communications, researchers outlined a new understanding of how energy moves within certain types of electrodes in cells, overturning the conventional wisdom that has reigned for more than 80 years.
