They could be the next generation of battery: so-called ’solid-state’ batteries. They’re made entirely of solid materials and have no liquid medium between their poles, as today’s batteries do. These types of batteries could extend the range of electric cars and make them safer, as they can store more electricity and are less flammable. So far, however, they have suffered from limited lifetimes. A team from the Max Planck Institute for Polymer Research has studied the processes that reduce the lifespans. Its findings could help build longer-lasting solid-state batteries. ...
