They die because batteries are essentially a type of electrochemical cell. An electrochemical cells works by reacting 2 different metal solid electrodes with a solution containing the same metals but in an aqueous solution. For example when magnesium electrode is put in a beaker containing magnesium nitrate solution and a silver electrode is put in a silver nitrate solution and the two electrodes are connected together we get electricity flowing through the wire. However when this occurs electrons flow from magnesium electrode to the silver one. When that happens there is a build of a negative charge on the magnesium electrode. At the same time there is a build up of a positive charge on the silver electrode. So we connect a tube called a salt bridge to allow some of the ions in the silver solution to travel to the magnesium solution and vice versa. Now that you know how a battery works you can understand how it stops working. Now as the exchange is happening through the salt bridge to balance the charges on both sides there is a build up on the electrodes. This build prevents the electrode to come in contact with the solutions they are submerged in. When that happens the reaction stops and the battery dies.

∙ 13y agoschool is a place where the electricity requirement is large. in batteries we cant store high amount of current and those will quickly become exhausted . i think we cant power our circuits in school by using batteries better we shall go for power supplies
ANSWER: The real reason is that battery are much safer for students trying to learn then active power supplies. Plus batteries are a hell of a lot cheaper then an active power supply

∙ 13y agoYes, although a battery should really be described as a method of storing electricity.

∙ 13y agoLithium is more dangerous than alkaline, but it saves space and is lighter due to its lithium contents.

∙ 12y agoIf you through away a battery, acid will slowly escape its hold and get into the ground which leads to plants and animals getting harmed, and acid in pipes leading straight to our homes!

∙ 13y agoBatteries have a special electric juice in them that responds to electronics to power them its either them or a cord plugged into a wall hope this helps:)

What is the main use for lead?
The main use of lead (79%) is in batteries.
Way you can use chemical energy?
when you use batteries you use chemical energy. Batteries contain stored chemical energy that can be changed to heat, light, sound or mechamical energy.Chemical energy is energy stored in the arrangement of particals of matter.
What is a button cell?
A button cell is a small battery that is usually used in small electronics that usually has a use for sound. Also, it can be found in larger batteries like AA and AAA batteries.
What are the examples of materials at home that use chemical energy?
batteries baking powder washing powder
Is lithium in batteries?
Yes. All lithium is the same: the element lithium (Li). Lithium carbonate itself is not typically used in batteries however. You can have lithium metal (neutral) or lithium ions (positively charged). Lithium carbonate is composed of lithium ions, and there are actually both lithium ions and lithium metal in batteries.
What type of batteries do Cybershot Cameras use?
These cameras use rechargeable Lithium Ion batteries. The batteries are not a standard size such as AA batteries, but additional batteries are available from Sony and other manufacturers.
Do batteries use nuclear energy?
Batteries use chemical energy to create voltage to drive current flow. They do not use nuclear energy.
Do aeroplane use batteries?
In most cases yes, they use batteries to start the engine.
Which devices use ag13 batteries?
AG13 batteries are alkaline batteries. They are the button type of batteries that can be used in various devices. The most common devices to use ag13 batteries are watches, calculators and medical devices.
How do batteries affect the microwave?
You don't use batteries in microwaves.
What type of batteries do ipods take?
they use rechargable batteries
What batteries do you use for your Guitar Hero Aerosmith controller?
Just use regular AA batteries.
How could you use lightning instead of using batteries?
You could not use lightning instead of batteries.
Does solar panels use batteries?
no solar panals don't use batteries because the sunlight is the batteries. the sun is a resource of batteries. the solar panels take energy from the sun, then at night it use the energy from the sun that is collected in the day.
Do flashlight use batteries?
Of course flashlight use batteries,no batteries means no power. I have a Imalent flashlight with remote control,very fashion,lol
Can I use regular batteries in a digital camera that takes rechargable batteries?
Yes you can. Just don't mix the normal batteries with the rechargable batteries because these are two different kinds of batteries and mixing them might cause harm to your device. Only use one or the other.Also look at your instruction manual for use of the camera and if it clearly says don't use regular batteries then follow their advice.
Where are the batteries on beats headphones?
Headphones do not use batteries, they use a power source such as an iPod or mobile phone.
