Abstract

Flexible, yet powerful batteries are needed to power numerous devices, and a simple battery with liquid electrodes would be highly flexible. Because of the chemical advantages of lithium-ion batteries, materials common in lithium batteries but as solutions could be used to create a highly productive and flexible battery. The purpose of this experiment was to create and test a simple battery using liquid electrodes, but with the relative strength of a lithium-ion batteries. It was hypothesized that if aqueous lithium carbonate were used as the cathode material in a simple battery, the battery would produce more power than if hydroquinone were used as the cathode. A suspension of graphite and water in a mass ratio 1:2.4 was placed in a 50 mL beaker. Also, 0.1 molar Li2CO3 (aq) was placed in another 50 mL beaker. A wire was placed with one end in each beaker to allow electrons to flow. The same was done again with Hydroquinone instead of Li2CO3. The power produced in volts by Lithium Carbonate (M=0.23, SD=0.17) was significant, t(9)=3.72, p=0.002 when compared to 0. The power produced in volts by Lithium Carbonate (M=0.23, SD=0.33) and by Hydroquinone (M=0.23, SD=0.17) do not differ significantly, t(13)=1.32, p=0.10. Therefore, aqueous lithium carbonate can be used as a liquid battery material though will need more testing to show greater production than other liquid batteries.
