摘要： A battery, such as a lithium-ion battery, comprises a first electrode, a second electrode, a molten salt electrolyte, and an electron collector, associated with the first electrode, the electron collector comprising an electrically conducting film. The battery further includes a protection layer separating the electron collector and the first electrode, the protection layer comprising a carbon-containing material. The electron collector may be an electrically conducting material such as aluminum, aluminum alloy, copper, nickel, other metal (such as alloys), conducting polymer, and the like. In one example, the protection layer is a graphite layer. In other examples, the protection layer may be a fullerene film, carbon nanotube film, or other carbon-containing material.

摘要： 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.
