In this work we present a data-driven approach to the rational design of battery materials based on both resource and performance considerations. A large database of Li-ion battery material has been created by abstracting information from over 200 publications. The database consists of over 16 000 data point

Section snippets Materials and methods. Sample anodes and cathodes were used in the experimental thermography testing. It was desirable to use electrodes that were as similar as possible to electrodes used in commercial batteries, so the primary goal in the selection of electrode materials was to imitate commercial electrodes.
Burrs are defects which can occur at the edges of battery electrodes, for example during the slitting process of manufacturing. They can cause a decrease in battery performance due to troubles, like short circuits, and lead to safety and reliability issues. Burr detection is an important part of battery-production quality control.
High-performance battery electrodes are a critical component of lithium-ion cells. The coated electrode materials for cathodes and anodes must meet high requirements for energy efficiency, storage density, and safety. Good coating quality on …
