Significance and problems to be addressed
The growing concern on global warming, greenhouse gas emissions, air pollution, and the excessive exploitation of fossil fuels has triggered the establishment of an alternative sustainable society by developing clean and renewable energy sources. Batteries will play a pivotal role in sustainable society development because of the following reasons:
(1) Batteries for energy storage in electricity networks is becoming increasingly important due to the intrinsically intermittent nature of such renewable energy source and the achievement of a temporal decoupling between energy production and consumption.
(2) To reduce the dependency on fossil fuels and mitigate CO2 emissions in transport sector as well as inner city air pollution, electric vehicles (EVs) and hybrid electric vehicles (HEVs) have been set as another governmental strategy also as the research focus for most of the automotive companies, where batteries will be an essential factor again.
Meanwhile, the sustainable development also calls for the sustainability of batteries themselves, and using materials from wastes as raw materials for preparing both electrodes and electrolytes has become an important strategy to reach the target of sustainability. Therefore, developing sustainable batteries is essential
To create ecosystem in the EU Interreg Nord program area for future lithium-ion battery concepts, this project aims to develop sustainable solid-state lithium-ion batteries from each component to assembling and scale-up, where the complementary competences from one Swedish and one Finnish partner (with three research units) will be combined.
The Swedish partner will use their competence in ionic liquids to (1) synthesize ionic liquids from waste-biomass and (2) use them to prepare ionic liquid-based composite solid electrolytes and as electrolyte-additives.
The Finnish partner will use their competences in electrodes, inorganic electrolytes, and coating to (1) develop and optimize sustainable active electrode materials based on the bio-carbon prepared from waste-biomass, (2) develop inorganic solid electrolytes from waste and abundantly available raw materials (e.g., ashes and clays), and (3) assemble the solid-state battery cells with new coating approach and characterize the battery performance.
