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.

锂基聚阴离子氧化物正极

聚阴离子氧化物阴极比过渡金属氧化物阴极具有更好的热稳定性和安全性，并且它们的电池电压也高于具有相同氧化还原对的氧化物类似物的电池电压。磷酸铁锂是第一个商业化的锂离子电池聚阴离子阴极。
