The present invention relates to articles of manufacture having a formulation distributed therein, wherein the formulation comprises an active agent which manifests a desirable property when released from the articles of manufacture. The present invention also relates to methods for manufacturing these articles of manufacture, to vehicles for applying the formulation to these articles of manufacture, and to perception indicators indicating the presence and the amount of formulation comprising an active agent applied to an article of manufacture.

Articles of manufacture releasing an active ingredient

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.

Battery with molten salt electrolyte and phosphorus-containing cathode

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.

Corrosion protection using carbon coated electron collector for lithium-ion battery with molten salt electrolyte

An example battery according to an embodiment of the present invention includes a positive electrode, a negative electrode, and an electrolyte. The positive electrode comprises a positive active material, and has a positive electrode area and a positive electrode capacity. The negative electrode comprises a negative active material, and has a negative electrode area and a negative electrode capacity. The battery has an electrode area ratio equal to the positive electrode area divided by the negative electrode area, and an electrode capacity ratio equal to the positive electrode capacity divided by the negative electrode capacity. In an example battery, the electrode area ratio is at least approximately one, and/or the electrode capacity ratio is at least approximately one.
