Abstract
A lithium-ion battery comprises a negative electrode, a positive electrode, and an electrolyte including a molten salt. The positive electrode comprises an electroactive compound including phosphorus, oxygen, lithium, and at least one other metal or semi-metal. The combination of such electrode compositions and a molten salt electrolyte provides a battery with very high thermal stability. Other ions, such as alkal metal ions, may be used in place of lithium ions for applications in other battery technologies.
