NAT1830: Batteries Lecture Notes

Flashcards covering key concepts and vocabulary related to batteries, as discussed in the lecture.

Oxidizing Agent

A substance that causes another to lose electrons (be oxidized).

Reducing Agent

A substance that causes another to gain electrons (be reduced).

Galvanic Cell

A type of battery that converts chemical energy into electrical energy through spontaneous reactions.

Oxidation

The loss of electrons from a species.

Reduction

The gain of electrons by a species.

Standard Reduction Potential

The tendency of a species to be reduced, measured in volts.

Half-Reaction

A reaction that shows either the loss or gain of electrons for a particular species.

Electrolyte

A substance that produces ions in solution and allows for the conduction of electricity.

Anode

The negative terminal of a battery where oxidation occurs.

Cathode

The positive terminal of a battery where reduction occurs.

Spontaneous Reaction

A reaction that occurs without needing external energy, often indicated by a positive redox sum.

Lithium-Ion Battery

A rechargeable battery with high energy density and efficiency.

Lead-Acid Battery

A type of battery commonly used in cars, consisting of lead and lead dioxide plates.

Environmental Impact

Effects caused by battery production and disposal, including pollution and habitat destruction.

Battery Recycling

The process of collecting and reprocessing used batteries to prevent environmental harm.
