By using block copolymer based electrolytes , physical and electro(chemical) properties can be individually tuned to fulfill the requirements posed by lithium metal batteries. The present study demonstrates that an ultra‐short poly(ethylene oxide) in combination with high amounts of lithium salt, stabilized by non‐removable solvent molecules, can lead to superior lithium ion conductivity in a broad temperature range, while keeping mechanical stability.
