WattRank

WattRank tool collects data on all types of energy storage technologies - batteries, supercapacitors, redox flow batteries etc., and creates plots that compare their performance

Motivation  

In order to accurately assess the performance of an energy storage device we need to make a comparison with its counterparts. However, it can be difficult to find complete and up-to-date data for these comparisons, such as energy plots, cycle life, or Ragone plots.

WattRank was created with the goal of creating a user-friendly resource for scientists, battery enthusiasts, reporters, investors, and others to find current data on all types of energy storage technologies. I hope, that this tool will help to standardize and improve the quality of performance comparison plots used in research papers and reports and serve as a valuable database for future studies.

Currently, WattRank focuses on commercial and in-development cells and packs. In the future there will be separate version for research data from papers and shared by scientists.
