Stanford University scientists have created a new ultrahigh surface area three-dimensional porous graphitic carbon material that significantly boosts the performance of energy-storage technologies. Previously reported sulfur electrodes often had areal capacity of below 3 mAh g −1 and cycling lifetime of less than 200 cycles.

Berkeley Lab battery scientist Nitash Balsara, working with collaborator Joseph DeSimone of the University of North Carolina at Chapel Hill led the effort on the hybrid electrolyte. Ceramic electrolytes, on the other hand, do conduct well at room temperature but require a great deal of pressure to maintain contact with the electrodes.

Today’s technologies for making biofuels all rely on photosynthesis—either indirectly by converting plants to fuels or directly by harnessing photosynthetic organisms such as algae. This process is less than 1% efficient at converting sunlight to stored chemical energy. NC State University. Engineering E. of Georgia).
