SEED

Currently considered the best option for electric vehicles and grid storage, lithium-ion batteries (LIBs) are based on solid electrodes separated by a liquid electrolyte between which lithium (Li) ions are reversibly exchanged during charge and discharge. Efficient Li+ transport is vital for ensuring good performance. Scientists have been trying to apply the LIB concept to other more abundant ions to reduce costs. However, the unfavourable mismatch between solid electrode host structures and ion radii or too large charge/radius ratios has resulted in limited progress. The EU-funded SEED project aims to tackle this issue by intercalating solvated ions into solid electrodes. In this way, the project will enable the reversible storage of a variety of ions in advanced host structures.
