Introduction to batteries
What do electric cars have that a normal fuel-powered engine does not
Motor
This element is considered "white gold"
Lithium
What are the 3 types of hydrogen fuel productions?
Grey (fossil fuels CO2 in the air)
Blue (Fossil fuels CO2 in the ground)
Green (Renewable energy source to make H)
a type of rechargeable battery that uses lithium ions to store chemical energy
Lithium Ion Battery
Where does combustion occur in a vehicle?
In the engine block
The battery in an electric car acts as ______ of that electrical energy while being driven and not plugged in.
storage
What 2 sources is lithium primarily found in?
hard-rock mineral deposits and subsurface brine pools
What process does Green Hydrogen undergo when splitting water?
Electrolysis
a clean fuel that when used in a fuel cell produces only water as a byproduct
Hydrogen Fuel
Biogas (methane) is produced when _____ is not present in the chemical process
Oxygen
Hybrid
What type of metal is lithium
Alkali metal
Draw the balanced equation of electrolysis of water.
2H2O -> 2H2 + O2
a method for “splitting water” into hydrogen and oxygen that uses electricity
electrolysis
Formed when one atom transfers electrons to another, creating oppositely charged ions that attract each other electrostatically.
Ionic bonds
When a battery discharges, atoms in the anode material _________ and become positive ions
Anode
Provide 3 cons of using lithium - ion batteries
- Source of mining
- Initial carbon footprint when created
- Difficult to recycle
- Highly flammable
- Loses battery storage over time
What 2 components do hydrogen fuel cells share with batteries
Both have a cathode and an anode
the positively charged end of a battery by which the electrons leave a device
anode
What is the name of the process that makes bioethanol a usable fuel?
Fermentation
True or false: Electrons CAN pass through the electrolyte
False: They cannot pass through the electrolyte and escape through a wire in order to power a termincal.
Provide 3 benefits of using lithium - ion batteries.
Lightweight
Can be made in a variety of sizes. Small for your cell phone, large for a Tesla.
Can store large amounts of energy
Holds a charge longer than traditional batteries such as AA, AAA, or 9V
Heat resistant
List 2 difficulties with using hydrogen as a fuel source
- Hydrogen pumps are not prevalent in many states
- Difficult to store and transport
- Need a lot of it to fuel a car
- Difficult to produce without CO2 emissions
the negatively charged end of a battery by which the electrons enter a device
Cathode
What is the chemical reaction of Combustion? (Written in chemical equation form)?
Fuel + O2 -> CO2 + H2O(g) + Energy
