Development Focuses In Separators The separator is a thin membrane that electronically isolates the positive and negative electrodes while providing a porous medium for ion transport via the electrolyte. It can also serve safety functions like slowing dendrite penetration to the opposing electrode and, in the event of a short, slowing thermal runaway. Areas of technology development in 2024 included wettability, ion selectivity, and safety. Celgard demonstrates a separator with improved wettability vs typical controls, potentially decreasing required cell soak time.
