2.65 volt Aluminum Ion (Geopolymer/Silicate) Battery

BigAtticHouse has built a working prototype of an Aluminum-Ion (2.65v) battery based on simple recyclable materials availble in developing low-tech areas. Our goal is to create a manual, translatable for localized use, that small scale entreprenuers and users can follow to create cheap rechargable cells for home use. The battery is our most advanced to date, and uses easily accessible materials. The cell can also be recycled after its end-of-life cycle, into clay and aluminum.

1.2 to 1.7 billion people have no access to reliable lighting once the sun goes down. Lead acid cells are prevalent, but have a high environmental and societal cost. Lithium cells contain hazardous, flammable liquids, and strategic, rare metals. By focusing development on geopolymer-based chemistries, we've been able to create a medium voltage (2.65v) secondary (rechargable) battery using easily recycled materials. The resulting waste, if any, is easily recycled into Aluminosilicate clays and smelted Aluminum. The same chemistry may also work with Titanium, or Magnesium for improving cell performance and voltage. These materials are far more abundant on earth than lithium and flourine and related materials used in more powerful battery systems.

The goal isn't to create a battery that can power a car or other portable devices, it's to create a storage mechanism that can be cheaply manufactured in a low-tech environment for use in lighting and charging of mobile devices. A "good enough" battery for billions of users.
