摘要

确定Butler-Volmer (BV)方程动力学参数(交换或腐蚀电流和Tafel斜率)的传统方法存在严重缺陷。本文在观察到BV方程是二阶线性齐次微分方程解的基础上，提出了BV方程的线性变换。该方法提供了一种非常简单的多元线性计算方法，可适用于平衡电位或腐蚀电位附近较窄或较宽的极化范围。在模拟和实测数据序列上测试了线性化形式的性能。

Linear transformations of the Butler–Volmer equation

The conventional ways of determining the kinetic parameters (exchange or corrosion current and Tafel slopes) of the Butler–Volmer (BV) equation have serious drawbacks. In this paper linear transformations of the BV equation are proposed, based on the observation that the BV equation is a solution of a second-order, linear, homogeneous differential equation. The proposed method offers a very simple multilinear calculation method which can be applied in narrower or wider polarization ranges around the equilibrium or corrosion potential. The performance of a linearized form was tested on simulated and measured data series.

期刊介绍： Electrochemistry Communications is an open access journal providing fast dissemination of short communications, full communications and mini reviews covering the whole field of electrochemistry which merit urgent publication. Short communications are limited to a maximum of 20,000 characters (including spaces) while full communications and mini reviews are limited to 25,000 characters (including spaces). Supplementary information is permitted for full communications and mini reviews but not for short communications. We aim to be the fastest journal in electrochemistry for these types of papers.
