The Biggest Problem with Solid State Batteries May Finally Be Solved Dendrite formation has long plagued researchers working on solid state batteries.
These tiny tree like structures grow from the lithium anode during charging, piercing the solid electrolyte and creating internal short circuits that can lead to battery failure.
The answer lies in hydrostatic stress, according to a recent breakthrough published in Nature by the Max Planck Institute for Sustainable Materials (MPI SusMat).
