Holy crap - and I thought 40% efficiency from the zinc air battery was lousy.
Can a battery be made outta stuff that's highly reactive? Like aluminum and bromine? I guess that's the limiting factor with chemical batteries - heat. I wonder if there's any way to reduce the heat output while pushing more electrons? -----Original Message----- From: thomas malloy [mailto:[EMAIL PROTECTED] Sent: Thursday, August 25, 2005 2:46 PM To: [email protected] Subject: The Aluminium Battery I contacted Electropositronium. I received an executive summary and a .pdf encrypted file which shows an anode and a cathode with various sized balls in between. I assume that the balls are the nanostructures that make the system work. They also included a discussion of the amount of energy that the system could hold. It assumed an efficiency of 20%. I assume that this is because only 20% of the available aluminium reacts. Batteries get warm when they charge and discharge, but not that warm.
