Batteries: Electricity though chemical reactions
Primary batteries can lose around 8% to 20% of their charge over the course of a year without any use. This is caused by side chemical reactions that do not produce current. The rate of side reactions can be slowed by lowering temperature. Warmer temperatures can also lower the performance of the battery, by speeding up the side chemical reactions.
The Anatomy of a Battery
Look closely at the cylinder-shaped battery in the picture. It has two ends: one has a part that sticks out on its top. Next to it, you can see a little plus (+) sign. This is the positive end of the battery, or cathode. The completely flat end of the battery has a minus (−) sign next to it. This is the negative end of a battery, or anode.
