A Cathode Active Material (CAM) is a industrial material that is used in the battery cathode to facilitate electrochemical reactions.
- Context:
- It can (typically) participate actively in the redox (reduction-oxidation) processes during the Battery Discharge and Charge Cycles.
- It can (typically) determine the Voltage, Capacity, Energy Density, and Safety of the Battery.
- It can range from being a Lithium-Based Cathode Material (like LiCoO2, LiMn2O4, LiFePO4) in Lithium-Ion Batteries to being a Lead Dioxide in Lead-Acid Batteries.
- It can (often) be characterized by its Crystal Structure, Electronic Conductivity, Ionic Conductivity, and Thermal Stability.
- It can be synthesized by various Chemical Processes, including solid-state, sol-gel, co-precipitation, and hydrothermal methods.
- It can be a focus of Material Science Research aimed at improving Battery Performance and Eco-Friendliness.

- Example(s):
- Lithium Cobalt Oxide (LiCoO2), commonly used in consumer electronics.
- Lithium Iron Phosphate (LiFePO4), known for its thermal stability and safety.
- Lithium Manganese Oxide (LiMn2O4), with a high discharge voltage and thermal stability.
- Nickel Cobalt Aluminum Oxide (NCA), used in electric vehicles for its high energy density.
- Nickel Cobalt Manganese Oxide (NCM or NMC), offering a balance of energy density, power, and safety.
- …
- Counter-Example(s):
- Anode Active Material, such as Graphite in Lithium-Ion Batteries, which is used in the anode instead of the cathode.
- Electrolyte Material, like Lithium Hexafluorophosphate (LiPF6), which is not active in the electrodes but serves as a medium for ion transport.
- Inactive Battery Material, such as binders or separators, which do not participate in electrochemical reactions.
