> Nickel-hydrogen batteries can run for tens of thousands of cycles, giving them a life of over 30 years. Their use of expensive platinum catalysts kept them relegated to space applications until five years ago, when Stanford materials science and engineering professor and battery entrepreneur Yi Cui’s team found an inexpensive nickel-molybdenum-cobalt alloy catalyst for the battery that costs $20/kg.I’m really curious about this part. The reason why this technology never took off was because of the need for platinum as a catalyst. If this is solved, it makes this chemistry one of the interesting around today. It’s durability is legendary, and it will be a game changer if it could be made cheap.
