Graphite for lithium-ion batteries

Offentlig prosjektsammendrag

There is a fast growing demand for sustainable sourcing of key materials for usage in Li-ion batteries (LIB). Graphite is one of the main components typically representing around 15 weight percent of the total battery. Todays graphite used in LIB is produced with large environmental footprints mainly in China and contributes with a large share of a LIBs final CO2 footprint. Vianode aims to develop and industrialise a process and products that carries with less than 5% of the emissions compared to state-of-art graphite. This is done through optimisation and development of new processes with much higher energy/resource efficiency and with less emissions, capable of producing high quality synthetic graphite for LIB for use in applications which require high performance such as electric vehicles. This project focuses on developing methods to improve fast charge capability through surface modifications, new Si-graphite composites with higher energy density, use of bio-based raw materials and processes that enable reuse and recycling of graphite. The projects will also develop new and improved methods for characterising the material properties and also the performance in cells in addition to advanced data analysis linking final cell perforamance to production parameters.
