How can the electrodes of batteries be made more efficient? In the journal Angewandte Chemie, American scientists describe a powerful approach that uses solvated graphene frameworks as the anode material. Assembled in a lithium coin cell, the as-made electrode excelled with capacities surpassing the values of typically used graphite.
