Active Dendrite Suppression by Ferroelectric Membrane Separators in Rechargeable Batteries [PDF]
Nano LettersAnodic dendrite formation is a critical issue in rechargeable batteries and often leads to poor cycling stability and quick capacity loss. Prevailing strategies for dendrite suppression aim at slowing down the growth rate kinetically but still leaving possibilities for dendrite evolution over time.
