Next Big Future: Nickel Zinc batteries 35% more energy than NiMH but half the cost of lithium ion

Next Big Future: Nickel Zinc batteries 35% more energy than NiMH but half the cost of lithium ion: "PowerGenix makes a variation on nickel metal hydride (NiMH) batteries, which are often used in hybrid vehicles (which have a conventional engine to back up the batteries). The company has created a nickel zinc (NiZn) battery that has 35 percent higher power and energy density than NiMH, but is half the cost of a lithium-ion battery (which still has a third more energy than a NiZn battery), according to its CEO, Dan Squiller."
