INNOVATIONS WITH BATTERIES Joseph Dowd, jvd18@pitt.edu, Mahboobin 10:00 Nick Gaydos, nag63@pitt.edu, Sanchez 10:00 REVISED PROPOSAL – Innovation is happening at a faster rate than ever, and most of this new technology will require a power source. Thus, new and better power sources must be created. The ideal power source will be able to provide energy for all of these sources, while also being as mobile as the device it is powering. A new battery is needed, ideally one that is long lasting, has a higher power density, and can be recharged. There are different types of batteries that are better for each of those three things. Lithium ion batteries have some of the best power densities, being several volts higher than others. However, they don’t last incredibly long, only capable of going through a couple thousand cycles at most [1]. Lithium is also not incredibly abundant on earth, so eventually we will run out of it. Sodium ion batteries could be an alternative source to lithium, as they share most of the same properties as a lithium ion battery except sodium is more abundant in nature. A downside of the sodium batteries is that they don’t have the same level of power density, but that is made up for with its availability. Nickel hydrogen batteries can last much longer than lithium ion batteries, maintaining power for over twenty thousand cycles. They don’t have the same level of power density though, as they have an average density compared to most batteries [2]. The problem is finding a battery that will do all of the necessary tasks as well as having an abundant source of material to make it. The key is to find the properties that will allow for all of the different properties that will make an ideal battery in one single compound. This will involve testing many different compounds for their ability to achieve this goal. The process of improvement could be long, but will be worth it when there is eventually a battery that can last years and power many different technologies. There are several possible alternative batteries options as opposed to the ones people use today but which new technology should be the one to replace current lithium ion battery. This paper will explore new and upcoming battery types to determine which battery technology makes the most sense to switch to. [1]Oliveira, L., Messagie, M., Rangaraju, S., Sanfelix, J., Rivas, M.

(Accession No. 110348359) This article, from a peer reviewed journal on the topic of power sources, discusses the different possible alloy combinations that can be used in nickel hydrogen/hydride batteries to increase the amount of hydrogen that can can be stored by the battery. It discusses two specific possible alloy arrangements to achieve this end. Here is an article created for the “Journal of Cleaner Production. Several groups of different disciplines came together to produce this article about a common connection between them all, batteries. The article explores several issues with using Lithium-Ion batteries. These issues include a bad environmental impact and major resource depletion. We will utilize this article to help elaborate on the issues with societies current battery sources. Juan, P., Xiaohong, W., Tianyi, Z., Siwei, L., Jinghe, L., & Kyriakos, K. (2016).

Nanotechnology, 27(4), 1. doi:10.1088/09574484/27/4/045701 This peer reviewed journal article discusses a specific type of micro supercapacitor that can be used for energy storage and use. It talks about a solid state micro supercapacitor with graphene and polymer electrolytes. These capacitors have shown promise when used in conjunction with some battery types to create a very effective battery. Jung, Y. S., Oh, D. Y., Nam, Y. J., & Park, K. H. (2015).

One major issue expressed in this article is the flammability of liquid electrolytes within current lithium batteries. This article can be used to explore the possibility of improving the current battery technologies rather than switching to another. This peer reviewed journal article is about the applications of graphene used on solid state supercapacitors to increase their effectiveness in areas such as recharge/discharge rates, power density and total capacitance. This can be used to help create a battery system that is more effective than a regular battery on its own. Smithrick, J. J., & O'Donnell, P. M. (1995, January).

Electrochimica Acta, 178, 392-397. http://dx.doi.org/10.1016/j.electacta.2015.08.019 For this article, two researchers from the NASA Lewis Research Center collaborated on a research project to provide a thorough overview on various options of nickelhydrogen battery designs. This paper also reviews technical accomplishments with batteries. There is more than one battery design with nickel and hydrogen, each design has its own specific applications and usefulness. This research can be applied to our paper to show some current battery designs and the advantages as well as disadvantages to the different battery types. This source is an article from Electrochimica Acta discussing sodium ion batteries. It describes the way that a graphene layer on the battery would allow the sodium charge density and and capacity, making it a viable option to replace lithium ion batteries. Sodium ion batteries are much cheaper to make and more environmentally friendly making them an ideal alternative. Chandler, D. (2015, August 17).

(1994). Alloys for hydrogen 2 Nicholas Gaydos Joseph Dowd http://news.mit.edu/2015/solid-state-rechargeable-batteriessafer-longer-lasting-0817 The news article from MIT News explains how researchers at MIT and Samsung are developing a new type of battery that proves to be a valid alternative battery type to those used today. This new technology does away with the use of highly flammable liquid transferred electrolytes. In addition to the safeness of the battery, the life expectancy is put over one hundred thousand recharges and it is expected to last even longer than that. This batteries are know as solid state batteries. This source fits into our paper as one of the potential emerging technologies that could eventually be the battery to replace lithium-ion type batteries. 3
