Dataset Description

This dataset describes an analysis of research documents about the debate between hydrogen fuel cells and
lithium-ion batteries within the context of electric vehicles.

To create this dataset, we first analyzed news articles on the topic of sustainable development. We searched for related science using keywords in Google Scholar. We then identified subtopics and selected one specific subtopic: electric vehicles. We started to identify positions and players about electric vehicles [1].

Within electric vehicles, we started searching in OpenAlex for a topic of reasonable size (about 300 documents) related to a scientific or technical debate. We narrowed to electric vehicles and batteries, then trained a cluster model [2] on OpenAlex’s keywords to develop some possible search queries, and chose one.

Our final search query (May 7, 2024) returned 301 document in OpenAlex:
Title & abstract includes: Electric Vehicle + Hydrogen + Battery
filter is Lithium-ion Battery Management in Electric Vehicle
We used a Python script and the Scopus API to find missing abstracts and DOIs [3].

To identify relevant documents, we used a combination of Abstractkr [4] and manual screening. As a starting point for Abstractkr [4], one person manually screened 200 documents by checking the abstracts for “hydrogen fuel cells” and “battery comparisons”. Then we used Abstractkr [4] to predict the relevance of the remaining documents based on the title, abstract, and keywords. The settings we used were single screening, ordered by most likely to be relevant, and 0 pilot size. We set a threshold of 0.6 for the predictions. After screening and predictions, 176 documents remained
