Polybenzimidazole Composite Separators Engineered from MOFs‐HNTs Composites Applicated in Lithium‐Ion Batteries

half-cells assembled with this composite separator show a discharge capacity of 161 mAh·g⁻¹ and a retention rate of 97.96% after 200 charge-discharge cycles. The separator also demonstrates excellent electrode stability in the plating/stripping test of Li symmetric cells, lasting up to 1600 hours and effectively inhibiting dendrite growth on the Li anode. This approach provides a promising solution for high-performance LIBs separators and paves the way for advancements in LIBs technology and energy storage applications.
