   en.wikipedia.org/wiki/Molten-salt_battery

   2 battery that it called a sodium–metal halide battery, with a 20-year lifetime. Its cathode structure consists of a conductive nickel network, molten salt electrolyte, metal current collector, carbon felt electrolyte reservoir and the active sodium–metal halide salts.

4. Hydrargyrum quartz iodide - Wikipedia

   en.wikipedia.org/wiki/Hydrargyrum_quartz_iodide

   Hydrargyrum quartz iodide (HQI) is a trademark name of Osram's brand of metal halide lamps [1] made for general floodlighting, arena floodlighting, shop and commercial and industrial lighting. Hydrargyrum is the Latin name for the element mercury. When heated, mercury vapour is created inside the lamp, and deposited when it cools.

5. ZEBRA battery - Wikipedia

   en.wikipedia.org/wiki/ZEBRA_battery

   The ZEBRA battery is a type of rechargeable molten salt battery based on commonly available and low-cost materials – primarily nickel metal, the sodium and chloride from conventional table salt, as well beta-alumina solid electrolyte. It is technically known as the sodium–nickel–chloride battery, and sometimes as a sodium–metal–halide ...

6. Metal halides - Wikipedia

   en.wikipedia.org/wiki/Metal_halides

   The halogens can all react with metals to form metal halides according to the following equation: 2M + nX 2 → 2MX n. where M is the metal, X is the halogen, and MX n is the metal halide. Sample of silver chloride. In practice, this type of reaction may be very exothermic, hence impractical as a preparative technique.

7. Metal–halogen exchange - Wikipedia

   en.wikipedia.org/wiki/Metal–halogen_exchange

   In organometallic chemistry, metal–halogen exchange is a fundamental reaction that converts an organic halide into an organometallic product. The reaction commonly involves the use of electropositive metals (Li, Na, Mg) and organochlorides, bromides, and iodides.
