Scientists Create Safe And Affordable Battery. Technology Wins Award For Large-Scale Energy Storage
A new safe, affordable, and sustainable battery for energy storage has been developed at the Organic Electronics Laboratory of Linköping University. The new technology is based on two major innovations: the manufacturing of wood-based electrodes in a laminated form and a new type of water-based electrolyte.
The result was published in the scientific journal Advanced Energy and Sustainability Research. The technology has been patented and will be commercialized by the spin-off company from Norrköping, Ligna Energy AB, which received the award for best “Startup for Climate” during the recent COP26 in Glasgow.
The increase in the share of renewable energy in the energy mix and the rising electricity consumption in society are causing major challenges for the balance of energy supply networks. In principle, electricity is consumed at the moment of its production, and there are currently limited options for storing large amounts of electricity. The problem is particularly acute during cold periods when electricity demand is highest. The imbalance in the grid can lead to severe power outages.

Potential Output Energy Is Sufficiently High For The Technology To Maintain Energy Balance In Electricity Supply.
Professor Xavier Crispin and his colleagues at the Organic Electronics Laboratory of Linköping University have developed a concept for large-scale energy storage that is safe, affordable, and sustainable. The potential output energy is sufficiently high for the technology to maintain energy balance in electricity supply.
“Our results enable the safe and environmentally sustainable storage of organic energy with high power density, 5 kW/kg, where the electrodes are made from wood-based material in a printing press. However, we need to increase the energy density: our organic batteries are better than regular supercapacitors and have almost the same performance as lead-acid batteries. But lithium-ion batteries are better,” says Xavier Crispin.
Previous attempts to develop a sustainable energy storage system based on cheap, water-based organic electrolytes with carbon-based electrodes faced issues with rapid self-discharge: it has been challenging to achieve more than a day.
Battery Uses A New Type Of Water-Based Electrolyte And Electrodes Made Of Lignin, A Cheap Byproduct Of Paper Manufacturing, Readily Available.
The excellent results presented in the article are based on two discoveries: a new type of water-based electrolyte and electrodes made of lignin, which is a cheap byproduct of paper manufacturing, readily available. The researchers developed a polyelectrolyte consisting of a highly concentrated water-based polymer, potassium polyacrylate, together with lignin biopolymer (as the positive electrode) and polyimide mixed with conductive carbon (as the negative electrode).
“The voltage drop, which measures self-discharge, is below 0.5 V in 100 hours, which is a world record for energy storage with organic electrodes in water-based electrolytes,” says Xavier Crispin.
And the new technology uses cheap raw materials: neither lignin, carbon, nor the polyelectrolyte costs more than 1 USD/kg. These are readily available and non-flammable materials, and the technology can be scaled up for large batteries. It is a sustainable solution for safe, large-scale energy storage.
