Dual Vertically Aligned Electrode-Inspired High-Capacity Lithium Batteries.

ABSTRACT: Lithium (Li) dendrite formation and poor Li⁺ transport kinetics under high-charging current densities and capacities inhibit the capabilities of Li metal batteries (LMBs). This study proposes a 3D conductive multichannel carbon framework (MCF) with homogeneously distributed vertical graphene nanowalls (VGWs@MCF) as a multifunctional host to efficiently regulate Li deposition and accelerate Li⁺ transport. A novel electrode for both Li|VGWs@MCF anode and LFP|VGWs@MCF (NCM₈₁₁ |VGWs@MCF) cathode is designed and fabricated using a dual vertically aligned architecture. This unique hierarchical structure provides ultrafast, continuous, and smooth electron transport channels; furthermore, it furnishes outstanding mechanical strength to support massive Li deposition
