Researchers from the Indian Institute of Technology Bhubaneswar, including Vinod Sarky, P. Laxman Mani Kanta, Shivangi Keshri, Mannanvali Shaik, B. R. K. Nanda, and Satyesh K. Yadav, have developed a comprehensive framework for evaluating and comparing the performance of electrochemical and electrical energy storage devices. This work, published in the journal “Energy Storage Materials,” aims to address the challenge of assessing the cyclic stability and overall performance of various energy storage technologies.
The team has created a multi-dimensional assessment framework that considers a wide range of parameters influencing the performance of energy storage devices. These parameters include the types of materials used, fabrication techniques, current density, operating voltage window, temperature, environment, and other relevant conditions. The framework is designed to rank cell performance based on essential metrics such as specific capacity and energy density, which are crucial for making well-founded comparisons between different devices.
The framework includes over 45 fields that capture detailed information related to materials, processing techniques, cell information, electrochemical testing parameters, and cyclic charge-discharge performance. One of its distinctive features is the ability to accommodate data from both experimental and theoretical sources, such as Density Functional Theory (DFT) and Machine Learning (ML) predictions. This allows for effective comparison between experimental results and computational predictions, providing a more comprehensive understanding of device performance.
For the energy industry, this framework offers a standardized method for evaluating and comparing various energy storage technologies. By providing a detailed and multi-dimensional assessment, it can help researchers and developers identify the most promising materials and techniques for improving the performance of energy storage devices. This, in turn, can accelerate the development of more efficient and reliable energy storage solutions, which are crucial for integrating renewable energy sources into the grid and supporting the transition to a low-carbon economy.
