As we move toward an increasing electrification of society, there is a tremendous need for better-performing batteries. However, battery systems are complex and there are many processes in the charge and discharge that need to be understood to develop new materials and chemistries for more efficiency energy storage technologies. In particular, the interfaces and interphases in batteries are crucial for the lifetime, safety, and durability of the systems, but are difficult to characterize and monitor due to the nanoscale dimensions and evolving structure and chemistry during the battery operation. The requested Electrochemical Quartz Crystal Microbalance with Dissipation Monitoring (EQCM-D) is a state-of-the-art, non-invasive, and surface-sensitive technology for time-resolved and quantitative analysis of interfacial reactions and interactions at the anode-electrolyte and cathode-electrolyte interfaces in various battery systems, such as lithium-ion, zinc-ion, and solid-state batteries, and zinc-ion capacitors. The EQCM-D will provide invaluable information about the mass and mechanical properties, and the formation and evolution of interphases that otherwise cannot be extracted using other techniques. The EQCM-D will be an integral part of an in-situ characterization platform at the University of British Columbia, which will strong support the research and training programs in the design, development, and implementation of new energy storage technologies for a cleaner world.

随着我们朝着越来越多的社会电气化迈进，对绩效表现更好的电池非常需要。但是，电池系统很复杂，充电和放电中有许多过程需要理解以开发新材料和化学，以获得更大的效率储能技术。特别是，电池的接口和相互重点对于系统的寿命，安全性和耐用性至关重要，但是由于纳米级尺寸以及电池运行过程中不断发展的结构和化学性能，很难表征和监测。 The requested Electrochemical Quartz Crystal Microbalance with Dissipation Monitoring (EQCM-D) is a state-of-the-art, non-invasive, and surface-sensitive technology for time-resolved and quantitative analysis of interfacial reactions and interactions at the anode-electrolyte and cathode-electrolyte interfaces in various battery systems, such as lithium-ion, zinc-ion, and solid-state batteries,和锌离子电容器。 EQCM-D将提供有关质量和机械性能的宝贵信息，以及相互重点的形成和演变，否则无法使用其他技术提取。 EQCM-D将是不列颠哥伦比亚大学的原位表征平台的组成部分，该平台将在设计，开发和实施新的储能技术方面的研究和培训计划中强烈支持更清洁的世界。
