Rechargeable aqueous zinc-ion batteries (RAZIB) are emerging as promising candidates for renewable energy storage devices, offering superior electrochemical performance, enhanced safety, and economic viability. However, the uncontrolled parasitic reactions and the growth of zinc dendrites resulting from nonuniform deposition impede the practical application of RAZIBs. Herein, inspired by the biological role of bamboo parenchymal cells (BPC), a biomimetic electrolyte additive was introduced to enhance the performance of RAZIBs. Abundant, readily extractable, and environmentally friendly BPC additives integrate the structural characteristics of inorganic materials and the advantages of organic materials. (1) BPC acts as the rich Zn²⁺ reservoir on the anode by adsorbing Zn²⁺ from the electrolyte, significantly mitigating concentration polarization. (2) The three-dimensional (3D) polyhedral structure of BPC provides numerous active sites to homogenize Zn²⁺ flux and inhibit two-dimensional (2D) diffusion on the anode. (3) BPC can suppress hydrogen evolution corrosion and guide Zn deposition toward smoother and denser crystal planes. Consequently, the symmetrical cells containing BPC can stably cycle over 3000 h with minimal voltage hysteresis, and the half-cells exhibit a high average Coulombic efficiency (99.67%) over 380 cycles at 5 mA cm^–2. Our strategy demonstrates a zincophilic biomass material for constructing a uniformly zinc-rich and fast-transporting interface layer at the anode interface, paving the way for the sustainable utilization of biomass materials applied in the field of energy storage.

Bamboo Inspired 添加剂对锌枝晶的抑制


可充电水性锌离子电池 （RAZIB） 正在成为可再生能源存储设备的有前途的候选者，具有卓越的电化学性能、增强的安全性和经济可行性。然而，不受控制的寄生反应和不均匀沉积导致的锌枝晶生长阻碍了 RAZIBs 的实际应用。在此，受竹实质细胞 （BPC） 的生物学作用的启发，引入了一种仿生电解质添加剂来提高 RAZIBs 的性能。丰富、易萃取、环保的 BPC 添加剂融合了无机材料的结构特性和有机材料的优点。（1） BPC 通过从电解质中吸附 Zn²⁺ 作为阳极上富含 Zn²⁺ 的储层，显着减轻了浓度极化。（2） BPC 的三维 （3D） 多面体结构提供了许多活性位点来均质 Zn²⁺ 通量并抑制阳极上的二维 （2D） 扩散。（3） BPC 可以抑制析氢腐蚀，并引导 Zn 沉积向更光滑、更致密的晶面。因此，含有 BPC 的对称电池可以在 3000 h 内稳定循环，电压滞后最小，并且半电池在 5 mA–² 下在 380 次循环中表现出较高的平均库仑效率 （99.67%）。我们的策略展示了一种亲锌生物质材料，用于在阳极界面处构建均匀富含锌且快速传输的界面层，为生物质材料在储能领域的可持续利用铺平了道路。
