Welcome to the Battery Knowledge Base

An open and free collection of battery knowledge, currently with 7257 entries that anyone can edit!

The Battery Knowledge Base is a platform for the battery community to share knowledge about battery research, innovation, and other activities. Like a "Wikipedia for the battery world", this knowledge base structures all information as part of a vast battery knowledge graph that helps humans and machines discover links between content!

Do you want to find collaborators with some expertise? Do you want to better understand the lithium-ion battery manufacturing process? Are you interested in the types of equipment for mixing slurries? Are you looking for an upcoming event to join? The battery knowledge base contains information to help you do all these things and more.

To try it out for yourself, you can:

Create a user page describing yourself, your organizations, your projects, and your expertise!
Explore an aspect of battery knowledge like manufacturing or modelling
Query the knowledge graph using the SPARQL endpoint!
