"MIT and Samsung researchers have developed a new approach to achieving long life and a 20 to 30 percent improvement in power density (the amount of power stored in a given space) in rechargeable batteries — using a solid electrolyte, rather than the liquid used in today’s most common rechargeables. The new materials could also greatly improve safety and last through “hundreds of thousands of cycles.”"

Another "almost there" revolutionary battery technology?
