Paper battery – Renewable energy storage for buildings
Researchers from the Digital Cellulose Center have developed a paper supercapacitor that can store renewable energy on a large scale. New research shows that the energy storage capacity of the paper battery is as efficient as conventional commercial supercapacitors. In the future, the energy storage device could be used in the construction of buildings to store energy on-site sustainably as well as insulate it."The energy demand will only increase, and we need new technologies to store...
Conductive organic ink – promising for storing solar energy
A new study from the Digital Cellulose Center demonstrates a method of printing sustainable, large-scale supercapacitors using cellulose, conducting polymers and carbonaceous materials. The new material shows promise for solar energy storage. Compared to previous findings, this method reduces costs by 90 percent while the capacitance was increased by 40 times.The new study from researchers within the Digital Cellulose Center shows that the combination of cellulose, PEDOT:PSS and carbon...

Bio-based membrane for hydrogen fuel cells – the DCC spinoff Cellfion
Bio-based membrane technologies developed by the Digital Cellulose Center have laid the foundation for the startup company Cellfion. In the future, their nanocellulose membranes will enable the fabrication of renewable energy storage devices, like hydrogen fuel cells and redox flow batteries, as well as replace the current non-renewable membranes on the market.The bio-based membranes from Cellfion are made of nanocellulose fibrils, a renewable material extracted from wood. The ion-selective...
New energy-efficient and low-cost method for making nanocellulose films
RISE researchers have developed a new low-cost method for manufacturing nanocellulose films, based on the Digital Cellulose Center’s research. The bio-based material can replace plastics in many products as well as be used in energy storage devices. By using suction and pressing instead of heat to remove water from nanocellulose mixtures, the energy consumption and costs can be reduced by more than 95 percent. A new pilot study conducted by researchers at RISE Research Institutes of Sweden...
Low-cost cellulose-based membrane can be used in energy harvesting devices
Hongli Yang is a doctoral student at the Digital Cellulose Center, and with her latest research, she has created a highly conductive, low-cost nanocellulose-based ionic membrane. The new membrane is promising for electrochemical energy technology, such as redox flow batteries. The abundant natural resource of cellulose, combined with a simple production process makes the new membrane low-cost compared to the current commercial non-biodegradable membrane.The research within the Digital...
