Two-dimensional (2D) layered materials are widely applied in energy devices including lithium-ion battery and supercapacitor due to their unique properties, such as tunable interlayer structure, numerous active sites, large aspect ratio versatile interlayer chemistry. In this work, 2D layered tungstate acid-linked polyaniline (TALP) presented a fluid-in-solid structure, which allowed facile exchange of the interlayer fluid from moisture to conventional Li⁺ containing electrolyte. With fast and stable dual ion storage (Li⁺ and PF₆⁻), TALP demonstrates high-rate volumetric capacity (39 mAh cm⁻³ at 2000 mA g⁻¹) and good stability (2000 cycles at 200 mA g⁻¹) within the working potential window of 1.5–4.5 V versus Li⁺/Li.

二维（2D）层状材料因其独特的特性（如可调的层间结构，众多的活性位点，宽高比的通用层间化学性质）而被广泛应用于包括锂离子电池和超级电容器在内的能源设备。在这项工作中，二维层状钨酸酸连接的聚苯胺（TALP）呈现出一种固体在流体中的结构，使层间流体从水分容易地交换为传统的含Li ⁺的电解质。通过快速且稳定的双离子存储（Li ⁺和PF ₆ ^-），TALP显示出高速率的容量容量（在2000 mA g ^-1时为39 mAh cm ^-3）和良好的稳定性（在200 mA g ^-1时为2000次循环））相对于Li ⁺ / Li在1.5–4.5 V的工作电位范围内。
