   New membrane extracts lithium with minimal environmental impact   
      
   A new membrane marks an important step toward more efficient   
   extraction of lithium which is needed for reusable batteries. The   
   design can also be used to extract other essential elements like   
   cobalt and nickel.   
      
   The membrane developed by the team extracts lithium using considerably   
   less energy, while maintaining higher selectivity.
