High voltage, room temperature single-ion polymer electrolyte for safer all solid state lithium metal batteries

All-solid-state batteries promise greater energy storage density and are cheaper and safer than traditional batteries for electric vehicles. A solid-state battery uses solid electrolytes and a lithium metal anode. The EU-funded PSIONIC project aims to advance the development of all-solid-state battery technology by using amorphous cross-linked polyethylene oxide laminated on the thin lithium foil at the anode and a high voltage cathode coated with a single-ion conductive polymer. This technological advancement will help to replace liquid electrolytes that are both flammable and unstable. The project will contribute to making all-solid-state batteries safer, cheaper, and more reliable and sustainable. This will lead to a higher uptake of battery-powered electric vehicles. The technology could be used for aeronautical activities.
