摘要

尽管电荷在电化学储能和工业安全中发挥着重要作用，但人们对液体中电荷的存在还相对缺乏研究。因此，量化液体和固/液界面的电荷分布对设备的效率和寿命至关重要。随着时间的推移，利用刺激来测量固体空间电荷的计量学已被移植到液体中。刺激会扰乱静电平衡，从而引起电反应。本研究利用压力波传播（PWP）方法测量双电层（EDL）中的电荷。它介绍了压力波振幅、液体电导率和液体性质如何影响电响应。

Space charge measurement at solid/liquid interface by PWP method

The presence of electric charges within liquid is relatively unexplored despite its role in electrochemical energy storage and industrial safety. Quantifying charge distribution in liquids and at solid/liquid interfaces is therefore crucial to the efficiency and longevity of devices. Over time, metrologies using stimulus to measure space charges in solids have been transposed to liquids. The stimulus disturbs electrostatic equilibrium to induces electrical response. This study builds upon measuring electric charges in the Electrical Double Layer (EDL) using the Pressure-Wave-Propagation (PWP) method. It presents how the pressure wave amplitude, the liquid conductivity and the liquid nature impact the electrical response.
