High temperature rechargeable battery for greenhouse gas decomposition and oxygen generation

Номер: US20130122381A1
Автор: Bruce S. Kang, Huang Guo
Принадлежит: Individual

This invention shows a high temperature rechargeable battery system for energy storage, oxygen generation, and decomposition of oxygen-containing gases (e.g. CO 2 /H 2 O, NOR, SO x , in particular greenhouse gas (GHG)) by using ODF/La 2 NiO 4 -based materials in Li/Ti/Mg-CO 2 battery architecture. Different from ionic Lithium conducting electrolyte, the invention has a higher ionic oxygen conducting electrolyte to work efficiently at elevated temperature without sacrificing safety. During battery discharge, GHG can be decomposed into syngas (CO+H 2 ) or solid carbon, while renewable energy (e.g. solar or wind power) can 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. With carbon capture and sequestration becoming a key element in worldwide efforts to control/minimize CO 2 emission, it can be anticipated that large amount of CO 2 will become available for use as feedstock for innovative conversions into synthetic fuels.
