Fabrication method for metal battery electrode with pyrolyzed coating

摘要

A method is provided for forming a metal battery electrode with a pyrolyzed coating. The method provides a metallorganic compound of metal (Me) and materials such as carbon (C), sulfur (S), nitrogen (N), oxygen (O), and combinations of the above-listed materials, expressed as MeXCYNZSXXOYY, where Me is a metal such as tin (Sn), antimony (Sb), or lead (Pb), or a metal alloy. The method heats the metallorganic compound, and as a result of the heating, decomposes materials in the metallorganic compound. In one aspect, decomposing the materials in the metallorganic compound includes forming a chemical reaction between the Me particles and the materials. An electrode is formed of Me particles coated by the materials. In another aspect, the Me particles coated with a material such as a carbide, a nitride, a sulfide, or combinations of the above-listed materials.

1. A method for forming a metal battery electrode with a pyrolyzed coating, the method comprising:
providing a metallorganic compound of metal (Me) and materials selected from a group consisting of carbon (C), sulfur (S), nitrogen (N), oxygen (O), and combinations of the above-listed materials, expressed as MeXCYNZSXXOYY;
where Me is selected from a group consisting of metals and metal alloys;where X is greater than 0;where Y is greater than 0;where Z is greater than or equal to 0;where XX is greater than or equal to 0;where YY is greater than or equal to 0; heating the metallorganic compound; as a result of the heating, decomposing materials in the metallorganic compound, forming a chemical reaction between the Me particles and the materials; and, forming an electrode comprising Me particles coated by materials selected from a group consisting of a carbide, a nitride, a sulfide, and combinations of the above-listed materials.
