固液界面的电化学势控制着各种化学和能量转换过程，但其电化学影响延伸到固体中的程度尚不清楚。本研究表明，最大可获取的电化学信息由单个无量纲因子\(u\)控制，\(u\)定义为液体与探针位置之间的有效静电间距与固体中静电传播长度之比。由此产生的通用平方反比标度与探针的微观细节无关。该衰减定律将静电屏蔽确定为跨固液界面信息传递的基本约束，为地下电化学传感提供了定量设计原则。
英文摘要
Electrochemical potentials at solid-liquid interfaces govern diverse chemical and energy conversion processes; however, the extent to which their electrochemical influence extends into the solid remains unclear. Here, we show that the maximum accessible electrochemical information is governed by a single dimensionless screening parameter $u$, defined as the ratio of the effective electrostatic separation between the interface and probe to the electrostatic propagation length in the solid. The maximum Fisher information follows a universal inverse-square scaling with this parameter. This relation identifies electrostatic screening as a fundamental constraint on information transfer across solid-liquid interfaces and provides quantitative design principles for interfacial electrochemical sensing.
