New battery technology could double capacities for consumer electronics

A startup called SolidEnergy says that it has developed a new design for a safe, rechargeable lithium metal battery, potentially revolutionizing energy storage for small devices like smartphones and wearables.
Breakthroughs in materials science mean that former MIT post-doctoral student Qichao Hu’s company can produce batteries with double the energy density of current-generation lithium ion batteries. This means that they can either be twice as powerful as a lithium ion battery of equiva
