Dendrites

Researchers have uncovered the mechanical properties of the nanoscale "thorns" that grow inside lithium batteries, which can cause them to short circuit or even combust. This paves the way to stop these growths forming, preserving battery power.

New research out of Rice University describes yet another promising possible solution to the problem of dendrite formation in lithium-based batteries, working a thin film of carbon nanotubes into the design as as way of drowning them out.​

Dendrites – thin conductive filaments that form inside lithium batteries – reduce the life of these cells and are often responsible for them catching fire. Now researchers claim to have produced an electrolyte that completely eliminates them while also boosting carrying capacity and efficiency.
