Mushrooms could boost your phone's battery

Anyone who uses their smartphone a lot notices that over time, the battery begins to lose steam and needs to be recharged more often. And the last thing you want is for your phone to run out of juice when you need it most.

From graphene hydrogels to high-performance anodes

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 ...

Inexpensive material boosts battery capacity

Battery-powered cars offer many environmental benefits, but a car with a full tank of gasoline can travel further. By improving the energy capacity of lithium-ion batteries, a new electrode made from iron oxide nanoparticles ...
