The document provides the basis for the development of homogenized performance metrics and a transparent reporting methodology at cell level, necessary for the reliable benchmarking of battery chemistries.
In this rapidly evolving field, while key performance indicators can be readily accessed, the performance evaluation and comparison of battery technologies remain a challenging task, due to the huge variation in the quality and quantity of data reported and the lack of a common methodology.
Whilst this development will not have an immediate impact on the benchmarking of battery technologies, it will set a best practice for the reporting of results. The impact of implementing such methodologies should become apparent within 3-4 years of its adoption in research projects and journal publications.
3. Development trends of power batteries 3.1. Sodium-ion battery (SIB) exhibiting a balanced and extensive global distribu tion. Correspondin gly, the price of related raw materials is low, and the environmental impact is benign. Importantly, both sodium and lithium ions, and –3.05 V, respectively.
For a successful implementation, the suggested reporting methodology needs to be adopted by most scientists and implemented in all battery research projects for monitoring the progress beyond the state-of-the-art. Editors and Board members of high- level scientific journals could greatly assist in the implementation of such recommendations.
Here’s a quick glossary of the key lithium-ion (li-ion) performance metrics and why they matter. 1. Watt-hours Watt-hours measure how much energy (watts) a battery will deliver in an hour, and it’s the standard of measurement for a battery.
