Lithium-based polyanion oxide cathodes

Polyanion oxide cathodes offer better thermal stability and safety than transition-metal oxide cathodes, and their cell voltages are also higher than those of the oxide analogues with the same redox couple. Lithium iron phosphate is the first commercialized polyanion cathode for lithium-ion batteries.

Automated summary

Polyanion oxide cathodes offer better thermal stability and safety compared to transition-metal oxide cathodes, with higher cell voltages. Lithium iron phosphate is the first commercialized polyanion cathode material for lithium-ion batteries.
