开发更好的电化学能量存储装置的驱动力不仅需要开发新材料，而且还需要更好地理解这种装置在操作期间的基础化学和动力学过程，为此需要新的分析技术。目前，很少有技术可以探测电池运行期间电解质中的局部组成和传输。在本文中，我们报告了一种新的应用磁共振成像（MRI）探测电化学过程中的一个模型电化学电池。使用MRI，运输和锌和氧在碱性电解质中的电化学，典型的锌-空气电池，进行了研究。电解质的磁共振弛豫图用于可视化在该模型金属空气电池放电过程中发生的化学成分和电化学过程。这些实验将有助于开发新的能量存储/转换设备以及其他电化学技术。
The drive to develop better electrochemical energy storage devices requires the development of not only new materials, but also better understanding of the underpinning chemical and dynamical processes within such devices during operation, for which new analytical techniques are required. Currently, there are few techniques that can probe local composition and transport in the electrolyte during battery operation. In this paper, we report a novel application of magnetic resonance imaging (MRI) for probing electrochemical processes in a model electrochemical cell. Using MRI, the transport and zinc and oxygen electrochemistry in an alkaline electrolyte, typical of that found in zinc-air batteries, are investigated. Magnetic resonance relaxation maps of the electrolyte are used to visualize the chemical composition and electrochemical processes occurring during discharge in this model metal-air battery. Such experiments will be useful in the development of new energy storage/conversion devices, as well as other electrochemical technologies.
