Lignin-based Sodium-Ion Batteries from Wood Waste
Researchers at Fraunhofer IKTS and Friedrich-Schiller-University Jena are developing a sodium-ion battery system based on lignin, a by-product of the wood and pulp industry.
Lignin, a biopolymer that gives wood its structural integrity, is typically incinerated for energy. The ThüNaBsE project, funded by the Free State of Thuringia and the European Social Fund, aims to reduce reliance on critical raw materials and promote safer, more sustainable battery technologies.
- The initiative is advancing the concept from raw material to a 1-Ah full cell.
- An industrial advisory board supports the work, featuring companies such as Mercer Rosenthal, Glatt Ingenieurtechnik, and EAS Batteries.
The goal is to develop a more sustainable battery technology.
