PROBLEM: BATTERIES TEND TO FAIL AT EXTREME TEMPERATURES. TESTABLE QUESTION: HOW AND WHY DO DIFFERENT BATTERY TYPES FAIL AT EXTREME TEMPERATURES? ELECTRO~CHEMISTY BATTERY FAILURE HONORS CHEMISTY RESEARCH PROJECT HISTORY OF THE BATTERY The battery’s origins may be followed back to very ancient times. We know that many of the “wise men” could have been exploring and testing electricity. For example, a clay vase, thought to be several thousand years old, was discovered in 1932 …showed first 75 words of 1850 total…

…showed last 75 words of 1850 total…to do: test the battery as if it were in those “everyday” conditions. A more scientific approach is to have a controlled experiment in which, we control our variable(s). HYPOTHESIS From research that I have been conducting I have pieced together this hypothesis: Once the battery’s temperature rises the EMF will increase, the when temperature continues to rise the EMF will fall, when the temperature decreases the battery’s EMF will decrease rapidly.
