摘要:

为提高电化学储能设备(电池、电容器和超级电容器)的能量和功率密度等性能,人们使用了一系列实验和计算工具。常见策略包括探索新材料化学、开发先进合成路线及将材料集成到设备架构的先进方法。但并非所有研究都在相同电池格式下测试,常用的按活性材料质量归一化的特定性能不可靠。我们提出新的质量归一化方法,即电化学参与者的质量,来计算特定性能,开发了全面报告材料、合成、电池组装及性能数据的框架,还创建了计算器来估算不同格式下的性能,有助于优化涂层厚度和活性材料负载,该框架可被期刊采用,我们还据此编制了数据库。

英文摘要:

Efforts to improve performance, like energy and power density of electrochemical energy storage devices (batteries, capacitors, and super-capacitors), are being made using a range of experimental and computational tools. The most common strategy involves exploring new material chemistries, developing advanced synthesis routes, and advanced ways to integrate these materials into device architectures. Although it is desirable to evaluate the performance of such efforts at a fixed cell format, not all studies conduct testing across the same cell formats. Specific performance normalized per mass of active material has been adopted as a universal indicator of performance, but it is not a reliable way to compare across cell formats. We propose a new mass normalization, i.e., the mass of electrochemical participants, to calculate specific performance. This new specific performance makes it possible to efficiently compare the efficacy of materials, synthesis, and cell assembly across different cell formats. We developed a framework to comprehensively report materials, synthesis, and cell assembly, and performance data, which facilitates succinctly reporting all performance indicators, including charge discharge curves over all cyclic stability assessments. The new specific performance and mass of the electrochemical participants per unit area of the electrode allows us to create a calculator to estimate performance at any commercial device-level cell format from measured data at the laboratory-level cell. The new specific performance also helps in optimizing the coating thickness and the loading of the active material. The framework can be adapted by journals to facilitate the reporting of data in a comprehensive way. Leveraging this framework, we have also compiled a database (hosted at https://power.tattvasar.com/) by extracting pertinent data from existing literature.
