摘要：
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.
