Instead of CCS technique, a possible approach to mitigate the greenhouse gas (GHG) emission is to decompose it into useful products. This invention shows a high temperature rechargeable battery system for decomposition of oxygen-containing gases (e.g CO/HO, NO, SO, in particular GHG), oxygen generation, and energy storage by using ODF/LaNiO-based materials in Li/Ti/Mg&#x2014;CObattery architecture. Different from ionic Lithium conducting electrolyte, the invention has a higher ionic oxygen conducting electrolyte to work efficiently at higher temperature without sacrificing safety. During battery discharge, GHG can be decomposed into syngas (CO+H) or solid carbon, while renewable energy (e.g. solar/wind power) could be used to charge the battery and generate oxygen. The energy consumption for GHG decomposition is self-sustainable and the byproducts (i.e. carbon/syngas and oxygen) have good market values. The adoption of cost effective materials other than Lithium is significant for scaled-up applications and represents an entirely new approach.

High temperature rechargeable battery for greenhouse gas decomposition and oxygen generation

The disclosure provides a method for the production of composite particles utilizing a mechano chemical bonding process following by high energy ball milling on a powder mixture comprised of coating particles, first host particles, and second host particles. The composite particles formed have a grain size of less than one micron with grains generally characterized by a uniformly dispersed coating material and a mix of first material and second material intermetallics. The method disclosed is particularly useful for the fabrication of oxide dispersion strengthened coatings, for example using a powder mixture comprised of YO, Cr, Ni, and Al. This particular powder mixture may be subjected to the MCB process for a period generally less than one hour following by high energy ball milling for a period as short as 2 hours. After application by cold spraying, the composite particles may be heat treated to generate an oxide-dispersion strengthened coating.
