Remember Metal-Air batteries? The ones that promise over 11 times the capacity of Lithium Ion? Well they are getting closer to a reality. A new composite material that combines nickel with perovskites while growing the carbon nano-tubes for support, then adds even smaller nano-tubes doped in nitrogen to form what appear to be tiny hairballs. Hairballs that may make this tech work.
The hopes are that eventually this process will yield many more cycles than previous metal air batteries. They are already testing well at up to 75 cycles before there is significant efficiency loss. This may not sound like many cycles, but for being barely 3 years old as a concept, this puts metal air batteries much closer to a functional reality.
What does this all mean? With power density in the neighborhood of 11 times greater, a lot. Take for instance the RAZR MAXX with its 3300MAH battery, if they can increase the number of recharge cycles while keeping even 10x capacity you would now be at 33000mah. So now finally, a Smartphone that can go all weekend!
I for one welcome our Metal-Air lanthanum-nickel-oxide catalyst hairball battery overlords. How about you?
