An Inexpensive Paper-Based Aluminum Air Battery

Ani Avoundjian, California State University, Los Angeles

Abstract

Paper-based batteries are an alternative to traditional batteries due to their low cost, portability, and simplicity to operate. In the present work, we demonstrate an improved and inexpensive paper-based aluminum-air battery employing KOH as the electrolyte. The dimensions of the device, electrode size, and electrolyte concentration were optimized. The maximum amperage of 17.43 mA and maximum power of 3.05 mW was achieved with a 9 cm2 battery with anode and cathode electrode areas of 5.1 cm2 and 3.75 cm2 respectively, using 1.5 M potassium hydroxide (KOH). The longevity of the batteries is greater than two weeks without addition of electrolyte. In a series configuration, the batteries generate sufficient energy to power light-emitting diodes (LEDs), a flashlight, a glucometer, and a pregnancy test.

Paper-based batteries are an alternative to traditional batteries due to their low cost, portability, and simplicity to operate. In the present work, we demonstrate an improved and inexpensive paper-based aluminum-air battery employing KOH as the electrolyte. The dimensions of the device, electrode size, and electrolyte concentration were optimized. The maximum amperage of 17.43 mA and maximum power of 3.05 mW was achieved with a 9 cm2 battery with anode and cathode electrode areas of 5.1 cm2 and 3.75 cm2 respectively, using 1.5 M potassium hydroxide (KOH).
