Cell Info Repository

Information about battery cells as structured, semantic, and linked data. This repository allows usage in knowledge graphs, websites, or Retrieval Augmented Generation.

Installation

To install the required dependencies, use the requirements.txt file:

pip install -r requirements.txt

For using the GraphRAG notebook, either an OpenAI API key needs to be provided (see https://platform.openai.com/docs/quickstart) or a local Ollama server should be set up (see https://github.com/ollama/ollama/).

Usage

Usage examples are provided in the following Jupyter notebooks:

• CreateBatteryTypeJson.ipynb: Instructions and examples on how to create battery type JSON files.
• DemoKnowledgeGraph.ipynb: Demonstrates how to build and query a knowledge graph using the provided battery cell data.
• GraphRAG.ipynb: Example of using Retrieval Augmented Generation with the battery cell data. Requires OpenAI API key or a local Ollama server.
