Study Notes
Electrochemistry and Battery Chemistry
- Quinhydrone electrode: A type of electrode used to measure pH. It consists of a platinum wire immersed in a solution containing quinhydrone (an equimolar mixture of quinone and hydroquinone). The electrode reaction involves the reduction of quinone to hydroquinone.
- Lithium-ion batteries (LIB): Popular rechargeable batteries consisting of a carbon anode, a lithium metal oxide cathode, and an organic electrolyte. The battery's reaction involves lithium ions moving between the anode and cathode during charging/discharging.
- Electrolytic and electrochemical cells: Electrolytic cells use electricity to drive non-spontaneous chemical reactions, while electrochemical cells convert chemical energy to electrical energy via spontaneous reactions.
-
Batteries: Devices composed of one or more electrochemical cells converting stored chemical energy into electrical energy.
- Primary batteries: Not rechargeable, examples include Zinc-carbon batteries.
- Secondary batteries (rechargeable): Can be recharged, examples include Lead-acid batteries and Lithium-ion batteries.
- Calomel electrode: A reference electrode that uses mercury in contact with mercurous chloride (calomel). Its electrode reaction involves the reduction of mercurous ions to mercury.
