# An analysis of our class experiment testing the durabilities and lasting power of batteries

Make sure to run multiple trials with each brand. If short circuit resistance is same, a cell of which the internal resistance equals 0. If you choose to use the CD player, find a CD, set it to repeat and run the player until the batteries die. A thermal-runaway model is developed with electrochemical and reaction model.

Depending on how involved you would like to make the project, you can either use the CD player or create a small resistive load to drain the batteries.

Review of Literature Different batteries perform better under different conditions. Results You can plot the results of your findings in a graph or chart, using the variables battery name and time that the battery lasts.

If you want to make a graph in Excel, look at our Graphing in Excel page. Abstract A thermal-runaway model of lithium-ion battery is developed by devising a resistive heating that includes short circuit current and integrating it with existing electrochemical and exothermic reaction model of lithium-ion battery.

Many companies create datasheets of their products. Record the time it takes for the light to go out. Light goes dimmer as the battery runs down After all the data has been recorded, average the times over each brand of battery. With the developed model, a guideline for designing lithium-ion battery is suggested to delay onset of thermal-runaway.

There are many extensions to this project. Similarly, you can use a flashlight to run the batteries down. Do lithium batteries last longer than alkalines? Previous article in issue.

Try to come up with your own additions. Do not limit yourself to just this guide. Remember, even if you cannot find any trends, that result is still significant. First and foremost, the simulation result obtained from developed mathematical model confirms that thermal-runaway is retarded when the area of heat transfer is augmented in the cells of same volume and capacity.

Next, it is also demonstrated that, under the simulation condition in which the loading level of active materials is set as a design variable, if short circuit resistance is same, thermal-runaway occurs in a lithium-ion battery with high loading level whereas thermal-runaway do not occur when the loading level is low.

Record the time it takes and repeat with each brand of battery. Flashlight Procedure The first step will be constructing an apparatus that can test the batteries. If you are more familiar with electronics, you may want to try creating your own circuit to test the batteries. For example, what are the differences in performance between the various types of batteries i.

Your discussion should focus on explaining any trends you found in your data. Graph the results and compare. By simply wiring an LED in series with a resistive load, you will be able to see the light grow dimmer as the battery runs down.

Conclusions This section is for you to fill in.Cheating to Pass the Test Experiment - During this experiment, we will be testing if children, grades 6th and 8th will be more tempted to cheat on a test if there is some type of reward involved for doing well.

During this experiment we will be using candy as a reward if the participate gets a 80% or higher average. Suppose an experiment is designed to test the durability of batteries in different conditions. All of the batteries tested are double-A (AA) Brand X.

All sets of batteries are preconditioned in different environmental conditions for exactly hours (1 week). Battery Testing Objective.

To test various types of batteries to determine which last the longest. Difficulty. Procedure: Easy. Concept: Easy. Concept. Have you ever noticed how the price of Duracell or Energizer batteries is significantly more than generic brands?

Does this price difference actually make a difference? Obviously, the goal here is to. degradation processes that lead to capacity and power fade in batteries, as well as improve our understanding on how such materials can improve the energy density, safety, and reduce costs of Lithium-ion batteries.

electrode materials for Lithium-ion batteries using coin cell testing. Specifically, the. Hydride and Lithium batteries under continuous and intermittent operations.

The rest of the paper is organized as follows: Section 2 provides a brief background of the battery types and characteristics. Sections 3 and 4 present our experimental setup and simulation results for both continuous and intermittent operations. Testing, Design, and Analysis Activity.
