Abstract

Achieving a Zn anode with simultaneous excellent cycling stability and high Zn utilization rate still remains a huge challenge for practical rechargeable zinc-ion batteries. Here, thermal transfer-enhanced layers are coated on both sides of Zn foil, where the top layer enables uniform Zn²⁺ flux and temperature distribution, and the bottom coating improves local heat diffusion and mechanical stability. With such dual thermal protection, thermodynamically driven dendrite growth and side reactions are effectively suppressed. The Zn anode can be stably cycled for 440 h at 5 mA cm⁻²/5 mAh cm⁻² (corresponding to a high Zn utilization rate of 85.5%), which is superior to previously reported results for protective layer-coated zinc anodes. A V₂O₃/N-doped carbon (NC)-based full cell exhibits stable performance for 200 cycles with a high specific energy density (174 Wh kg⁻¹, based on the whole mass of electrodes) and high volumetric energy density (218 Wh L⁻¹, based on the whole cell), which is promising for practical applications.

一种用于稳定和高能量密度锌离子电池的热传递增强锌阳极

实现同时具有良好循环稳定性和高锌利用率的锌阳极仍然是实际可充电锌离子电池面临的巨大挑战。在锌箔的两侧涂覆热传递增强层，其中顶层涂层使Zn2+通量和温度分布均匀，底层涂层改善了局部热扩散和机械稳定性。有了这样的双重热保护，热力学驱动的枝晶生长和副反应被有效地抑制。锌阳极在5ma cm - 2/ 5mah cm - 2下可稳定循环440 h（相当于85.5%的高锌利用率），优于先前报道的保护层镀锌阳极的结果。V2O3/ n掺杂碳（NC）基全电池在200次循环中表现出稳定的性能，具有高比能密度（基于电极整体质量的174 Wh kg−1）和高体积能量密度（基于整个电池的218 Wh L−1），具有实际应用前景。
