General information
- Short Summary
- A Bulgarian research institute with more than 50 years of experience in electrochemistry and energy systems has developed an innovative technology for a gas-diffusion electrode with zeolite, pre-hydrophobized carbon black and polytetrafluoroethylene applicable for metal-air batteries operating in a highly alkaline electrolyte, intended for energy storage from RES.
- Full Description
-
The Bulgarian research institute has more than 50 years of experience in the research and development in the field of electrochemistry. In the recent years it has developed novel approaches and technologies in the field of hydrogen generation and storage, fuel cells, battery systems, low cost intercalation compounds and nanostructured composite materials for batteries and others. The institute has experience in international joint projects and implementation of technologies in the industry.
The invention relates to rechargeable gas-diffusion electrodes based on zeolite, pre-hydrophobized carbon black and a catalytic layer and is characterized by the use of natural zeolite with a monoclinic crystal structure (clinoptilolite), which is further mixed with the pre-hydrophobized carbon black and hexane to provide better gas permeability, adhesion and increased stability. The electrode allows operation at low to medium high current densities. The technology concept refers to a composite gas-diffusion layer in which a synergistic effect was obtained when mixing zeolite and pre-hydrophobized carbon black. This effect is expressed in the partial preservation of electrical conductivity (compared to carbon-based GDL), as well as increased oxygen permeability (due to the structure of zeolites).
The institute seeks commercial agreements with technical assistance with companies interested in implementing the technology to a marketable product and testing of new application. It will provide the necessary know-how, training and expertise for operation, and adapt the technology to the needs of the company. Research organizations and companies with RD&I activities are sought. - Advantages and Innovations
- The invention is characterized by increased chemical, mechanical and electrochemical stability compared to all-carbon-based gas-diffusion electrodes. The gas-diffusion electrode is with high durability during operation, which allows its implementation in rechargeable batteries. The technology is characterized by an easier way of production and lower price in comparison to existing technologies. It has applications in energy storage and battery systems. The innovation provides high energy density, low cost and high stability.
