Abstract

The present invention provides an electrochemical flow battery for electric energy storage, the said battery uses anode reactive materials (the material being oxidized during battery discharge) selected from complexed ionic form of late 3d transition metals, i.e., Mn, Fe, and Cu. The battery has significantly low cost due to use of these relative inexpensive metals.

Description

Technical field

[0001] The invention relates to a flow battery for storing electric energy by an electrochemical method. Background technique

[0002] Due to the volatility and uncertainty of most renewable energy sources, such as wind and solar power generation, large-scale electrical energy storage is a necessary part of the effective use of renewable energy. An economic and reliable energy storage technology is also urgently needed in microgrid applications. Redox flow battery (RFB) is a potential energy storage technology that can be used in wind or solar power stations.

[0003] Power plants such as ships and submarines also require high-efficiency large-scale battery energy.

[0004] In the prior art, Skyllas-Kazacos et al. describe a redox flow battery using alum, which has very low cross-penetration between catholyte and anolyte (US Patent No. 4786567). Zito et al. describe a flow battery based on iron-sulfur electric pairs (US Patent No. 5,422,197). Skyllas-Kazacos et al...
