GreenBattery

Energy storage is an increasingly growing research area and electrical energy storage systems are in great need because of the rapid expansion of digital appliances, portable electronics, electric vehicles, etc. Batteries are one type of energy storage system with increased demand in recent years. 

Due to the increased demand for batteries, several Gigafactories are being built in Europe. Unfortunately, these are not yet following the principles of sustainability set by EU, because harmful or even toxic compounds are used in cell assembling, and active electrode material contains critical raw materials. The project want to develop a prototype of a biobased battery by using residual products from the forest industry such as (hydrolysis) lignin, bio sludge, fiber sludge, bark, ash and filter dust etc. 

The project will use (waste) biomass to replace fossil elements or toxic compounds in batteries. During cell assembly, specific focus is placed on the durability of battery cell lines, to meet the criteria for green transition at EU level.

RISE's role in the project is to develop bio-based battery components with high ionic conductivity and good compatibility with other components. For the project, RISE will produce crystalline nanocellulose (CNC) from various industrial side streams (e.g. fiber rejects) which will be used in the new bio-based components.

RISE will also carry out techno-economic analyzes to evaluate techno-economic parameters and compare bio-based batteries against traditional lithium batteries.
