Today, biofuels may conjure images of ears of corn or Priuses for US readers, but the domestic industry has been as much about politics lately as it has been about scientific innovation. While researchers and scientific organizations have looked into finding green energy sources in everything from human waste to humble algae,state and federal governments continue to tangle over how much of a priority this area should be.

Researchers “heal” destructive dendrite growth in lithium-metal batteries

Dendrites—branching structures that look like tree limbs—are fun to draw and good on neurons, but they’re generally best avoided in lithium-ion batteries. As ions are exchanged between the anode and cathode over several charge and discharge cycles, lithium electrodes will sometimes grow dendrites that can expand through the electrolyte that separates the anode and cathode. These dendrites can reduce the battery’s capacity, shorten the life of the battery, or even start fires as the dendrites heat up.
