Food Batteries: A Comparison....

?? Electrochemical conversion wind
?? Composed of hotshot or more(prenominal) cells
?? Stores & converts chemical energy into electrical energy
?? An electric current is a steady flow of electrons so a battery is
alike(p) a little Electron Factory
?? Chemical reactions that produce electrons argon called
electrochemical reactions

?? Created the first battery in 1800
?? Voltaic Pile
?? red-hot alternating discs of
zinc and copper on top of
one another. Between each
disc was a piece of cloth
that was soaked in brine.

?? The Parts of a Battery
?? 2 Dissimilar Metals Called Electrodes
?? Anode: Negative terminal figure; Oxidation sour (loss of electrons)
?? Cathode: Positive Terminal; Reduction process (gain of
electrons)
?? Electrolyte
?? Medium that provides ionic conductivity between the 2
electrodes
?? Case

?? The Chemical Process
?? The cations in the electrolyte are attracted to the Cathode and the
anions in the electrolyte are attracted to the anode
?? When a load (an remote device like a clock) is attached to the
positive and nix terminals by wires, the circuit is completed and
the electrons flow from the negative, through the device to the
positive, creating an electric current.
?? When the load is unattached, the chemical reaction stops, when it is
attached, the chemical reaction begins.





?? Two Types of Batteries
?? Primary Batteries
?? Disposable batteries
?? Designed to completely bring fall out their supply
of reactants then be thrown away.

?? Secondary Batteries
?? Rechargeable batteries
?? fag end discharge and then have their chemical reactions
reversed by supplying electrical energy to them, which
restores the chemicals to their original composition.

?? Connecting Batteries together
?? Parallel formation:
?? Positive to positive
?? Negative to negative
?? Adds up the amps,
not volts

?? Serial transcription:
?? Positive to Negative
?? Adds up volts,
not amps
