Cathodedataextractor is a lightweight document-level information extraction pipeline that can automatically extract
comprehensive properties related to synthesis parameters, cycling and rate performance of cathode materials from the
literature of layered cathode materials for sodium-ion batteries.
pip install cathodedataextractor
- It is built on open-source libraries: pymatgen, text2chem, and ChemDataExtractor v2 with some modifications.
- BatterySciBERT-uncased Multi-Label text classification model for filtering documents.
- Automated comprehensive data extraction pipeline for cathode materials.
- Paragraph Multi-Class classification algorithms for documents (HTML/XML) from the RSC and Elsevier.
- A normalised entity handling process is provided.
- An effective chemical abbreviation detection module.
- Heuristic multi-level relation extraction algorithm for electrochemical properties.
In addition, the pipeline is also suitable for string sequence text extraction.

'Apart from the conventional cationic redox of transition metals, '
'both Na-deficit and Na-excess materials have showcased the ability '
'to exploit oxygen redox activity as O2–/O2n– for a charge '
'compensation mechanism. To realize cathodes with enhanced energy '
'density, a technique like the incorporation of alkali metal ions '
'into transition metal layers has been adopted. Recent work by Boisse '
'(13) et al. displayed the impact of honeycomb cation ordering of '
'a highly stabilized intermediate phase for a Na2RuO3 cathode material '
'in instigating the anionic redox activity and providing a capacity '
'of 180 mAh g–1 at 0.2C with a capacity retention of 89% for over '
'50 cycles. More devoted efforts to realize the utmost potential '
'of anionic redox ought to be carried out in the future.')You can either report an issue on GitHub or contact me directly. Try gouyx@mail2.sysu.edu.cn.
