Super Battery By: LaToya Babbs, Laura Dionisio, Patrick Figaro, Nathan Hursh, Holly Krutka Capstone Design Project- University of Oklahoma - Spring 2003 INTRODUCTION From entertainment purposes such as personal walkmans and Nintendo Gameboys to today’s only version of communication featuring cell phones and laptops, batteries are essential to today’s lifestyle. The most used batteries right now are very compact and split 50/50 between rechargeable and non-rechargeable. Today’s commonplace batteries present the consumer with many problems. Either batteries that cost a fortune and must be replaced every few months, or they are relatively inexpensive, but quickly run out of energy and add harmful. Batteries should add convenience to the life of the consumer, instead of adding inconvenient and expensive problems. A question was posed as to whether higher capacity batteries based on unusual stabilized iron (VI) chemistry could meet the growing need of consumers (Licht). These super-iron batteries boast a 50% energy advantage over conventional alkaline batteries or the rechargeable batteries out on the market today. Also, because of their makeup, these batteries are more environmentally safe than those on the store shelves. This makes this battery enticing to penny pinchers as well as the environmental groups that seem to have a large influence in many important circles. Super Battery has then drawn up a plan to go about the construction and design of the components of this proposed Super-Iron battery. Justification is also presented as to why this makeup of a AAA is better than the original AAA batteries made by companies such as Duracell and Energizer. BASIC COMPONENTS The cathode is the section of the battery between the outside shell casing and the separator paper. During cell discharge, which is the reaction that occurs when the battery is in use, the cathode goes through a reduction reaction where it gains electrons. In the super-battery, a unique iron (VI) compound acts as the cathode. This substance is reduced from iron (VI) to iron (III) when it gains three electrons. The anode consists of the positively charged material, making up the interior part of the battery. It is made up of a zinc paste made in the production plant based primarily on zinc oxide and the metallic oxide chosen as calcium oxide. The final battery is constructed using a 304 stainless steel casing. In addition, a separator paper is used to keep the anode and cathode materials from coming into direct contact, while allowing the flow of KOH electrolyte solution. Finally, a brass current collector is necessary in order for the battery to use the flowing electrons for the various battery applications.

CATHODE SYNTHESIS The increased storage capacity of the super-battery is due to the iron (VI) compound, which is missing six valence electrons. This material is Na 2 FeO 4 , and its synthesis is one of the main challenges in the process. Figure 1 is a PFD that details the equipment and different steps involved with the production of Na 2
