Abstract

Aqueous Zn-ion batteries exhibit tremendous potential for large-scale energy storage applications due to the dual advantages of abundant Zn metal reserves and high theoretical capacity. However, practical applications are hindered by issues such as dendrite growth, electrode corrosion and hydrogen evolution. In this study, a composite anode composed of pre-deposited Zn on phosphorus-doped carbon nanotubes (P-CNT) is reported. On the one hand, the carbon nanotubes (CNTs) serve to reduce local current density during Zn deposition, enhancing corrosion resistance. On the other hand, the formation of a Zn₃P₂ interfacial layer facilitates more uniform Zn deposition, effectively suppresses dendrite growth, and mitigates the hydrogen evolution reaction (HER) to a certain extent. The composite anode exhibits a high coulombic efficiency of 98.9 % after 300 cycles. Furthermore, the full cell assembled with a LiMn₂O₄ (LMO) cathode demonstrates stable cycling performance over 900 cycles. This work presents a novel and robust design for a Zn metal anode in advanced aqueous Zn-ion batteries.

基于掺磷碳纳米管的复合锌金属负极的制备

锌离子水电池具有丰富的金属锌储量和较高的理论容量的双重优势，在大规模储能领域具有巨大的应用潜力。然而，实际应用受到枝晶生长、电极腐蚀和析氢等问题的阻碍。在这项研究中，报道了一种由磷掺杂碳纳米管（P-CNT）上预沉积Zn组成的复合阳极。一方面，碳纳米管（CNTs）降低了锌沉积过程中的局部电流密度，增强了耐腐蚀性。另一方面，Zn3P2界面层的形成使Zn沉积更加均匀，有效抑制枝晶生长，并在一定程度上减轻析氢反应（HER）。经过300次循环后，复合阳极的库仑效率高达98.9%。此外，用LiMn2O4 （LMO）阴极组装的电池在900次循环中表现出稳定的循环性能。本文提出了一种新颖而坚固的锌金属阳极设计，用于先进的水性锌离子电池。
