Researchers at McGill University in Canada have increased a battery’s energy density by adding a rare-earth metal to an anode.
The scientists added a small amount of neodymium (Nd) to the anode in a bid to increase its energy density without compromising safety. This resulted in a 19% increase in energy density.

PSR Analysis. While increasing the energy density of a battery is generally very good news, there have to be several caveats. First, it needs to be successfully commercialized and second, the rare earth neodymium, is another rare earth material which China dominates, so there is a potential bottleneck as China uses the minerals in geo-political bargaining.
