So techcrunch still runs one sided articles about companies that are basically glorified advertisements. They haven't changed after all these years. They did not dwell on the biggest difference between aluminum air and lithium batteries -- that the aluminum air ones are not actually rechargable. Whenever you run out of batteries you have to send each used battery back to the factory to be re-manufactured and get a new one. If you want to really compare these to lithium batteries, then you should compare the energy needed to re-manufacture a new aluminum air battery compared to the energy needed to merely recharge a lithium battery. I bet that the al-air battery will end up at least ten times more energy intensive. (Manufacturing aluminum is a very energy intensive process). And of course you also have to worry about shipping heavy batteries back and forth between the factory and multiple recharge centers. Whereas with lithium ion you are only "shipping" electrons over wires. Relying on single use battery for ordinary transportation is just crazy extravagance.
