Who: Yi Cui Ph.D (Stanford University) What: Lithium-Anode Battery Why you should care: 3x lithium power density 3x charging and discharging speed (Means same time to charge your phone now, but will last 3 times longer) Why you dont have it yet: Currently achieving Coulombic efficiency of 99.0%; charges 100 times before failure. Coulombic efficiency of 99.9% required for economic viability. (First team to get higher than 96% efficiency) Which leads to the biggest question on everyone’s lips: when will these batteries be available? Cui is typically matter of fact: Three years intense research and a commercial prototype in five years. In the last 13 years Cui has picked up 16 scholastic honours. If he and his team manage to commercialise the ‘holy grail’ battery, he can expect many more and they won’t only be academic. forbes/sites/gordonkelly/2014/08/30/holy-grail-battery-facts/
